From Windows to MEPIS
A Windows user's guide to MEPIS
Alan D Moore
Welcome to the land of MEPIS and Linux! Like many new Linux users, you probably have a good bit
of experience using Microsoft Windows, and you're not sure what to expect from this new operating
In years past, the learning curve for Linux was steep, with a user culture populated mostly by
hobbyists, programmers, and self-styled “hackers”; as a result, it gained a certain reputation as being
only good for servers, or requiring advanced computer knowledge just to do simple things.
Times have changed, however, and these days desktop-oriented Linux distributions1 such as MEPIS
provide a friendly environment that smooths out the transition and provides a desktop that even the
most average user can work with. In the words of MEPIS creator Warren Woodford, MEPIS was
designed to be “easy to try, easy to install, and easy to use”.
Even so, without some grounding in the fundamentals of Linux, especially in the areas which it differs
from Windows, many newcomers quickly become frustrated and give up on Linux before they really
get a chance to use it. With that in mind, I have written this “orientation” to help Windows users
migrate smoothly to MEPIS by highlighting the major differences you will encounter.
The Right Frame of Mind
A different tool requires a different approach
Suppose you are an experienced carpenter. Despite your experience, though, you've only ever used a
hammer and nails to fasten boards together. You're extremely skilled with a hammer and nails, so that
it only takes you one or two hammer blows to drive a nail perfectly. Now suppose that someone tells
you about wood-screws, and how much better they are for holding boards together. So you decide to
try them out: You get some wood-screws and a power screwdriver. You set the wood-screw against
the board and start whacking its head with the screwdriver in an attempt to nail it into the board. You
end up breaking the screwdriver while failing to drive the screw more than a few millimeters into the
board. Naturally, you conclude that wood-screws aren't as great as you were told.
Screws and nails are used to accomplish the same basic task: attaching two pieces of wood together.
However, they differ greatly in design, and therefore in method of operation. If you try to operate a
screw like a nail, or a screwdriver like a hammer, the results will be unsatisfactory and unfruitful. The
same could be said of Linux and Windows; both are designed to accomplish similar tasks, but because
they are designed differently, they each require a different method of operation.
When you try out Linux, you cannot expect to work with it the same way that you worked with
Windows and get good results. Some of your skills with Windows will transfer to Linux, but many
will not. If you try to operate a Linux system exactly like you operated Windows (especially if you are
1 See appendix B for an explanation of “Linux distributions”
an advanced user), chances are your efforts will end in frustration and possibly a broken system; and if
you judge Linux solely on how much it is or isn't like Windows, you are likely to be disappointed. The
best approach is to put aside your assumptions, follow the recommended practices, and try to get a
handle on how the system is designed to be used.
Some practical advice
Enough with the analogies, here are some practical points:
● Try it on a decent computer: Linux has earned a reputation for working well on older
hardware, and many people have used it to give a “second life” to an older computer running an
unsupported legacy OS. Even so, it isn't going to work miracles; if your hardware is defective,
broken, or extremely old, MEPIS will likely perform poorly and leave you unimpressed2. The
MEPIS website ( recommends an absolute minimum of 128 MB of RAM
and 2.5 GB of hard drive space to use MEPIS with at least a Pentium II processor, though it
cautions that these figures will give very poor results. It also states that MEPIS will give you
about the same level of performance you'd get from Windows XP on the same hardware.
● Don't judge performance by the live CD: The live CD3, which allows you to run a live
MEPIS session from a CD without actually installing, gives you a great way to get a glimpse of
the “look and feel” of MEPIS and see the kinds of applications you can run on it. But it is not
truly representative of an actual install; there are some things that won't work properly from the
live CD, and more importantly the performance of the live CD desktop is awful compared to an
actual hard drive install, especially on older machines. Bear these things in mind before passing
● It might not work 100% on your machine: Linux hardware compatibility has come a long
way. Most hardware should give at least basic functionality in Linux and be perfectly usable.
But there are still problem areas; some hardware requires extra tweaking or configuration, and
some hardware doesn't work at all. We'll discuss some of the most common difficulties later
● Start with the basics: It's amazing how many new Linux users start out by trying to run
Windows software in Wine5 or compiling software from source code to get the latest versions.
Start out slow, stick to the preinstalled software or software from the repositories6, and try to get
a feel for this new OS without trying to modify the system too much. Take some time to find
out what MEPIS can do well before trying to make it do things it might not do well.

Part I: Fundamental Differences
If you want to buy a stereo system, you have two basic options: an integrated system, or a component
system. An integrated system comes with everything in one chassis: CD player, tuner, speakers,
amplifier, equalizer, etc. It may have additional inputs for things like an mp3 player or turntable, but
essentially it's a closed system: you can't swap out the equalizer for one with more bands, you can't
trade out the CD player for an MP3 CD player, etc. A component system, on the other hand, allows
you to do just that: you can replace components that you don't like, or leave out components that you
don't need. You can even add exotic pieces like a DAT player or reel-to-reel if you require them, as
long as the right inputs and outputs are present.
Windows is, in many ways, like an integrated stereo system. It comes prepackaged with all the basic
parts; while you can add software to it, you can't really mess much with the basic system. You can
install Firefox or Mozilla, but you can't really remove Internet Explorer and replace it with one of
them; you can't rip out Windows Explorer and replace it with the Windows 3.1 desktop.
Linux, on the other hand, is like a component system. You can add, remove, or replace any piece of
software on the system, from the very lowest-level operating system components to the desktop
environment7 or core applications. This is why Linux has always been considered ideal for customized
solutions or for those who like to tinker. Of course, doing so requires a bit of knowledge, and many
people are content to have a system that “just works”, with or without the options.
MEPIS gives you the best of both worlds; although it still allows you the option of customizing your
system to your heart's content, everything you need to have a complete operating system (and more) is
preinstalled and configured. As you become a more experienced Linux user, you may find yourself
removing parts of the OS you don't use, installing tools that make certain tasks easier, or replacing
components to create an environment more suited to your needs or your computer's hardware. In the
meantime, it's only important that you understand that MEPIS is simply one combination of
components that have been packaged together for convenience; other versions of Linux, or even
another user's customized version of MEPIS, may contain very different components8.
The command line and the GUI To most Windows users, the command line interface (CLI) is a relic of the past that died with DOS; the
mere suggestion of interacting with a computer via typed commands tends to inspire everything from
revulsion to outrage in many new Linux users. Yet the command line interface remains alive and well
with many Linux users. It is a powerful tool with decades of development and user experience behind
it, augmented by a wide selection of command line applications and utilities that allow you to do
everything from system updates to CD burning. Nearly anything you can do through a graphical user
interface (GUI) can be done with greater speed and flexibility through the command line, and
eventually even “average users” find ways to exploit its power.
If you remain unconvinced, however, don't despair; MEPIS is made for you. MEPIS has a complete
graphical user interface with icons, buttons, menus, windows, and everything else you expect from a
modern computer system. You can install, administrate, and use MEPIS without ever touching a
command line. The power of the command line is still there if you wish to use it, but it is completely
Just bear in mind, as you interact with more experienced Linux users (especially if you are asking for

8 A good example of the modularity of Linux can be seen by comparing MEPIS with its derivative, AntiX. technical help), you are likely to see a lot of
command line usage going on. You may
even be expected to run some commands
yourself, if someone is helping you
troubleshoot a problem. This is not a
reflection on MEPIS's capacity to be
administrated graphically, but simply a
deeply entrenched part of Linux user
culture (which, despite criticism, is not
going to change anytime soon).
Configuration files
When you change a setting on Windows,
such as the color of your desktop or the
network address of your computer,
Windows stores that data in the “registry”.
MEPIS sports a complete graphical environment ­­ no The Windows registry is a database that
holds almost every bit of configuration data
command line required!
on your Windows operating system. It is
made up of binary9 files that can only be read from or written to by special software such as your
control panel applets or regedit.exe.
Linux does not have a “registry”. Instead, nearly all the configuration information on your system is
stored in discrete, human-readable text
files10. These files are usually referred to
as “config files” or “conf files”. In the
“old days”, administering a Linux system
was largely a matter of editing text files;
even now, the slick graphical tools we
have for administering MEPIS are doing
little more than making changes to text
files which knowledgeable users could
just as well edit directly11. As a new user
you probably won't be hacking into any
configuration files just yet, but it's
important to keep this difference in mind
as you learn more about Linux.
Part of the config file that controls video display
Case Sensitivity
Like all Linux distributions, MEPIS is case-sensitive. This means that “MEPIS.txt” and “Mepis.TXT”
are not the same file, and “FireFox” is not the same command as “firefox”. For “point-and-click”
users, this generally isn't an issue, but it's important to be aware of, especially if you use the commandline at all.
9 See “binary(file)” in Glossary
10 If you are old enough to have used DOS or Windows 3.1, you may remember “.ini” files which were used to configure those systems. Most Linux configuration files use a similar syntax and structure.
11 It's worth noting that typical Linux configuration files are meant to be hand­edited, and as such they are typically both easily readable, and heavily documented internally (with comments) and externally (in a man page or handbook). Contrast this to the Windows registry, which is largely cryptic nonsense understood only by the system's specialized configuration tools. File system
Basic file system structure
One of the first problems I struggled with as a Linux user was how the file system12 worked. If you
have been looking around your MEPIS system trying to find the “C:\” drive or “A:\” drive, you are
searching in vain. Linux handles storage media very differently.
On your Windows computer, each drive or partition receives a
letter, like “C”. The top-level directory on C is C:\ -- this is
called the “root” of C. Under that root directory, there are
various subdirectories and subdirectories of subdirectories
branching out into a tree structure we call the “file system” of C.
Each device contains its own file system.
Windows File System
On Linux, there is only one
file system, and its root is labeled simply “/”. When a storage device
is added to the system, it is attached to a directory or subdirectory of
the file system; this is called “mounting” a drive or device, just as
you might mount a trophy or picture to your wall. When you mount a
disk to a directory on the system, the contents of the disk appear
under that directory, and files or directories you create under that
directory will be on the new disk. By default, new devices are
usually mounted under the /mnt or /media directories (for instance a
floppy drive might be mounted to /media/floppy), but in reality they
can be mounted anywhere in the file system13.
The advantages of doing things this way may not be immediately
apparent, but think about this situation: you have a relatively small
Linux File System
hard drive in your system, and you find that it is filling up with
pictures and other files. You go out to the store and buy a second hard drive and install it in your
system. In Windows, the disk might show up as D:\ or E:\ (whatever the next free letter is, usually),
and you're going to have to copy your files over to it and remember to put new files on the new drive
from now on. In Linux, you would install the disk, copy your home directory to it, then mount the disk
as your home folder. After that, you would carry on just as before, without having to think about the
fact that a second hard drive is involved. It's just that suddenly your old home directory will have a lot
more room!
Important folders
MEPIS has several directories right under the root of the file system. These directories are based on
the Unix14 filesystem hierarchy standard, which you can read more about at As a new user, there are only a few of these directories you need to be
concerned with.
By far the most important to you is the /home directory. Under /home, each user on the system has a
12 See “file system” in glossary
13 It's worth noting that network file shares (such as shared folders on a file server or NAS) are mounted in the same way as physical devices.
14 See “Unix” in glossary
folder, called the user's “home folder”. By default this folder is the only folder on the system in which
you can save or edit files. Everything about your user account, from your desktop background to your
email messages, is saved somewhere in your home folder. This may seem restricting at first, as
Windows users are used to being able to put files anywhere on the system they want to. However,
keeping all your files, folders and settings in one directory makes it very easy to back up all your data,
and protects you from accidentally overwriting or deleting system files.
The next folders you want to know, which I've already mentioned, are /mnt or /media. Removable
devices, such as floppy drives, CD's and USB drives, show up under /media when you attach them to
the system. Additional hard drive partitions (such as your Windows partitions, if you are dual-booting)
show up under /mnt by default.
Finally, the /etc folder is where all the global configuration files are stored. You can think of it as the
Linux equivalent of the Windows registry15. If a program has global or default settings that can be
adjusted, you will find the appropriate text configuration file for it under /etc. Also, system settings
such as your network configuration, startup scripts, and file system configuration are stored in this
Users and security
Accounts and permissions
Linux, much like Windows NT, 2000, XP, and Vista, is an account-based operating system. This
means that every program that runs on the system does so under the credentials of a specific user
account. If a user “Bob” logs in and launches a web browser, the web browser is running on Bob's
account. If user “Mary” logs in and launches the same program, it is instead running with Mary's
credentials. No program can run without an account to run under, and no program running under a
given account can do more to the system than what that account has been allowed. If Mary's user
account does not have permission to save data to one of Bob's folders, no program Mary runs will be
able to do so either.
To simplify the management of multiple user accounts, account-based systems also implement
“groups”. A group is simply a collection of permissions and restrictions that can be applied to a user;
for instance, on MEPIS being a member of the “cdrom” group allows you to use local CD ROM drives,
while membership in the “scanner” group allows you to use scanning devices16.
As mentioned before, newer versions of Windows operate on this principle as well (3.1, 95, 98, and
ME did not); in theory Linux and Windows operate mostly the same in this respect. However, in
practice, there is a big difference. Most people set up their Windows user account as a member of the
“administrators” group, meaning that their regular user account has unlimited privileges on the system
(in fact, the user account you create in the setup wizard for Windows XP defaults to an administrator
account – with no password!).
On Linux, there is only one administrative account. It is called “root”, and it should only be used for
doing system administration and special low-level tasks. Do not operate your system as root for
normal tasks! Doing so undermines the whole security model of Linux.
15 See “Configuration files” under section I
16 Naturally, a user account can be a member of multiple groups, allowing you to have multiple system permissions. Users in MEPIS are, by default, added to a variety of groups.
Because we do need to run programs with root privileges, though (for tasks like installing software or
editing global configurations, for example), Linux provides us with ways of running individual
programs with root credentials without having to be fully logged in as root. The most common include:
kdesu: This command is for running graphical
programs as root in KDE17. To run a program with root
credentials, you would type “kdesu someProgram”,
after which you'll be prompted for root password18.
Administrator Mode: In the system configuration
tools, you may notice a button at the bottom of the
page on some configuration screens that says
“Administrator Mode”. Typically, if a setting involves KDE asking for your root password
global changes to the system, such as adding a printer
or setting the network settings, you need to have root privileges to do this. Just press the
“Administrator Mode” button and enter your root password.
su: This command is used on the command line to switch to another user account within a
terminal session. You can specify the user account, or specify no user account to become root.
sudo: This is a highly-customizable command that allows only specific programs to be run by
specific users with root privileges. MEPIS does not use sudo for anything by default, but it can
be configured if you need it.
When running a program as root, keep in mind that any user-specific configurations that you do will be
configured for the root user. If you later run the program as a normal user, you will no longer have
your specific configurations. For example, if you were to run the KDE settings utility as root and
changed the desktop settings, the changes would affect root's desktop, not yours.
It's tempting for many new Linux users who are used to Windows to want to try to disable as many of
these security measures as they can, and make their user as close to “administrator” as Linux will
allow, because this is common practice on Windows. There is really no clean way to do this, and in
any case this sort of thing should be avoided as much as possible. There is rarely any good reason to
have administrative privileges for regular use in a properly-designed system (which we like to think
Linux is).
Anti-virus, firewalls, and other security software
For many people, the switch to Linux is motivated by problems they've had with viruses or malware in
Windows. If this is part of your reason, you are probably interested in getting some anti-virus, antimalware, and anti-intrusion software going on your MEPIS system. Fortunately for you, MEPIS ships
with an excellent anti-virus (clamav) and firewall (guarddog) already installed.
There are veritable gigabytes of debate on the web about what the future holds for Linux viruses, and
whether the increasing popularity of the platform will prompt more viruses to be written for it. What is
beyond debate, however, is the current state of affairs on viruses and malware for Linux: there are
virtually none to concern yourself about. There are a handful of known Linux viruses, but the majority
of them are no more than proof-of-concept programs that never left the lab. The remainder largely
17 The GNOME desktop environment has a similar program, gksu, which can also be used under KDE. 18 The menu or desktop shortcuts for programs that typically require root privileges to use are already configured to run with sudo, kdesu, or gksu as appropriate in MEPIS. Thus, as a new user you probably won't have to worry about these commands much. depend on exploits limited to certain programs or distributions, most of which have now been patched.
And as for malware (spyware, adware, etc), it is unheard of to date.
Commercial software companies have made a fortune selling security as a product; but there is an old
adage that every security professional knows, “security is not a product, it's a process”19. In other
words, keeping your computer secure is not a question of what anti-virus or anti-malware products you
buy, or even whether you use Linux or Windows; it's a question of using your computer securely.
Where Linux excels over Windows is in providing us with tools and environments more conducive to
good security practices – tools that can be scaled to the knowledge and experience of the user.
What are these practices? As mentioned above, user security is vital; making limited use of the root
account and password goes a long way toward keeping your computer secure. But here are a few
Use your firewall to block incoming and outgoing programs that you don't use.
Remove or disable network-aware programs that you don't use.
Download software only from legitimate, trusted sources (the repositories are a good start).
Keep your computer behind a router on a private subnet, even if it's the only computer in the
Don't follow links in spam emails.
If someone using your computer doesn't follow good practices, limit their administrative access.
Update regularly. Nearly all updates you will get using the stable version of MEPIS will be
security patches.
If some of these terms don't make sense to you and you need more help with staying secure, see the
“getting help” section below. Good security on any operating system requires a certain amount of
technical knowledge, but fortunately MEPIS is fairly secure by default.

Using software Applications in MEPIS
Depending on what software you used in Windows, you may or may not see any familiar applications
the first time you log in to MEPIS. Although few well-known commercial applications are published
for Linux, a rich selection of free alternatives are available for easy installation (see the next section).
MEPIS even comes with many commonly used applications preinstalled and configured.

Keep in mind that these programs are not “drop-in” replacements for their Windows counterparts; they
are “equivalent alternatives”, so expect to do a little relearning and readjusting of your work flow
(remember that wood-screw analogy?).
Windows Applications in MEPIS
Despite the wide array of available free software for Linux, many new and experienced users find that
there are Windows programs they simply can't replace with Linux-compatible alternatives. There are a
few different approaches to dealing with this situation:
● Dual Boot: You can set up Linux and Windows on the same computer, selecting the OS you
want to use when you start the computer. The downside of this is that you have to reboot every
time you want to go back and forth between your Windows software and your Linux software.
● Wine and its derivatives: “Wine” is a program that provides Windows-compatible software
with a fake Windows environment to run in. Wine is not very easy to set up, and the results are
often disappointing (if you even get results). Still, it typically works great for smaller, older
applications that don't need to deal directly with your hardware, or for well-known applications
that have been out for a while (such as Microsoft Office 2000). Wine is free, but there are
several commercial derivatives that add user-friendly features and extended compatibility with
certain types of Windows Software. Cedega (which is designed for games) and Crossover
Office (designed for productivity applications) are the two leading products.
Virtual Computing: One of the newest solutions to the Windows software dilemma is to
simply run Windows on a “virtual computer” inside your Linux install. It requires a relatively
powerful computer with lots of memory, but when set up properly you can run Windows in a
window on your desktop and have instant access to your old software. The most popular
products for accomplishing this are VMware (free), qemu (free and open-source), VirtualBox20
(free and mostly open-source) and Parallels (commercial).
The biggest drawback to this approach is performance. Not only are you splitting your hardware
resources between two operating systems, but the “guest” system does not have access to your physical
hardware (it runs on emulated hardware). Thus, if you need Windows for resource-intensive
applications such as 3D gaming or multimedia authoring, dual-booting may be a better option.
Windows XP running in vmware. Think of it as "Windows in a window".
Installing software
When you install software from the Internet on Windows, you typically go to some download website,
download the software, unzip it, run some kind of installer program, go through a wizard, click a bunch
of “next” or “yes” buttons, then your software is installed. Not so bad, especially if you only have one
or two programs downloaded from the web.
But on Linux the vast majority of your software is downloaded from the web, even things like your
desktop environment21 and OS kernel22. So in order to keep track of it all, MEPIS uses a system called
20 MEPIS 7 includes the VirtualBox repository by default, but you need to activate it. After that, VirtualBox is installable via Synaptic.
21 See “desktop environment” in glossary
22 See “kernel” in glossary
Advanced Package Tool (APT). With the APT system, you don't have to go to websites or download
packages by hand; you use a single program, Synaptic, to find, select, install, and upgrade all the
software on your system. The interface is very easy and consistent no matter what software package
you install. In addition, Synaptic does a kind of “background check” on every package you install with
it, making sure you have all the required support software to run a given program, checking the
packages to make sure they haven't been tampered with or corrupted, and ensuring that you are getting
the latest versions available for your OS.
Installing software with Synaptic is a simple
point-and-click procedure. When you launch
Synaptic, you are presented with a massive list
of software packages that you can install. All of
the software packages listed are located on
special Web servers called “repositories”; you
can download the latest list by clicking the
“reload button”. Once you've done this, you can
locate software you want to install using the
search feature, or by browsing through category
sections like “games” or “graphics”. When you
find a package you want, simply select it and hit
“apply”. Synaptic automatically downloads the
package and any necessary support packages and
installs them. For more information about APT
and repositories, see this excellent article on
Installing software with Synaptic
Of course, not every software title you might like to run is in an online APT repository; or you might
want a newer version than the one available through Synaptic. There are several other methods of
installing software on MEPIS which vary in difficulty; I'll highlight them here briefly, but in the
interest of keeping things short, we won't go in to them in any detail.
Deb packages: The software packages installed through APT are in a format called
“deb” (short for “Debian”, the Linux distribution that came up with APT). You can manually
install deb packages using the command line tool “dpkg”, or the graphical tool “Kpackage”.
Keep in mind that installing deb packages this way does not automatically take care of
dependencies like APT does. You may need to manually install the dependencies of the
package, if it has any.
RPM packages: Some distributions of Linux use the RPM packaging system (short for RedHat
Package Manager, developed by RedHat Linux, of course). RPM packages are similar to deb
packages in many ways, and there is a command line program available on MEPIS to convert
RPM packages to debs called “alien”.
Source code: Any open-source program can be compiled from source if there is no other
option. This isn't as hard as it sounds most of the time, but sometimes you can run into errors
that require a little more skill to sort through. Source is usually distributed as a “tarball”23,
which is a compressed file (like a zip file) usually ending in .tar.gz, .tar.bz2, or .tgz.
Miscellaneous: Many software developers package software in their own custom ways, usually
23 See “tarball” in glossary
distributed as tarballs or zip files. They may contain setup scripts24, ready-to-run binaries25, or
binary installer programs similar to Windows “setup.exe” programs (these are often suffixed
with “.bin” or “.run” in Linux).
As I mentioned above, Synaptic can also be used to upgrade your system. This works similarly to the
“Windows Update” system you used in Windows, except that it not only updates your OS but all the
software on your system (at least, all the software you installed through Synaptic).
To upgrade, open Synaptic, click “Reload” to get the latest package information from the server, then
click “Mark all upgrades”. You can also click the “sections” button at the bottom of the window and
check out the software in the “Installed (upgradeable)” section. Sometimes, Synaptic will not
automatically mark an upgrade if the upgrade requires additional operations (which you might not want
it to do), such as installing or removing other packages. You can manually mark these for upgrade to
see what additional changes are required.
Because the repositories which MEPIS uses by default receive only security updates and minor bugfixes, upgrades are pretty safe and shouldn't cause problems on your system. However, as a general
rule, you should be cautious of upgrades that involve the following:
Kernel or driver upgrades (packages like “linux-image-2.6.x.x.”, or “modules-2.6.x.x”)26
Upgrades to the GUI engine (anything that says “xorg” in the name)
Upgrades to KDE (The MEPIS desktop environment -- usually says “kdebase” or “kdelibs”)
Upgrades that involve significant changes in version number. Usually, version numbers might
look a bit like this: 6.2.01-2. Although programmers don't have a 100% consistent approach to
these numbers, a change in one of the first couple of digits (e.g. moving 6.2.01-2 to 6.5.0 or 7.0)
generally indicates some kind of major change in the program. On the other hand, a change to
something like 6.2.01-3 is probably just a minor patch.
Before doing such upgrades, you may want to consult the MEPIS forums to see if anyone has had
problems with them. Generally speaking, though, unless you are running a beta version of MEPIS, or
have changed from the default repositories, you shouldn't see any “dangerous” upgrades.
24 See “script” in glossary
25 Also “binary”: see “binary” in glossary
26 Generally, the MEPIS kernel is NOT upgraded except between major version changes (e.g., 6.x to 7.x). If you are seeing a kernel upgrade available, chances are it is not a kernel from MEPIS. Check with the community forum, or look for an announcement at
Part III: Practical Considerations
Problems to expect
By far the hardest and most problematic part of switching to Linux is getting it installed and set up;
granted, MEPIS has probably the easiest and friendliest installation process in the history of operating
systems, but there are still some pitfalls to watch out for. If you have a computer made up of 100%
Linux-compatible parts and you plan to devote 100% of the hard drive to Linux, you should have no
problems. But most Linux installations are complicated by two factors: 1). installing on hardware that
is not completely Linux-compatible, and 2). wanting to dual-boot with Windows.
Hardware issues
The four big hardware trouble spots are wireless networking, dialup modems, laptop power
management, and 3d acceleration for video.
● Wi-fi: Support for wireless network cards has improved dramatically in recent years, but
because the technology itself is in a rapid state of development, Linux developers have not
always been able to keep up or get the information they need to write drivers. Fortunately, if
your card doesn't have a Linux driver, MEPIS has a utility called “ndiswrapper” which can
translate the Windows drivers for use in Linux. In addition to driver issues, support for some
forms of wireless authentication (such as certain types of WPA or EAP) is experimental and
● Modems: Many cheap, on-board or PCI modems are of a variety known as “winmodems”;
these are not true hardware modems, as they rely on software to do a lot of the work for them.
Unfortunately, the software involved is in some cases proprietary and only works on Windows.
MEPIS actually has pretty good support for a number of these “winmodems”, but they can still
be finicky and not all features are supported. If you have trouble with your on-board modem,
you might get counseled to get a “real” modem, which usually means a stand-alone serial
modem. All standalone serial modems communicate using a standardized command set that
works with any OS platform; if you must use dial-up, they are highly recommended.
● Laptop power management: Due to lack of standardization in laptop hardware, MEPIS may
require some additional tweaking to get the “hibernate” (a.k.a. suspend-to-disk) and
“suspend” (a.k.a. suspend-to-RAM) features working correctly on your laptop. You can
usually find help for your particular laptop model at
● Video: If you have an Intel or newer S3 graphics card, MEPIS usually provides 3d acceleration
“out-of-the-box”27. If you have an Nvidia or ATI graphics card, MEPIS includes a special tool
to install the proprietary drivers for these cards. If you have some other type of card, you
should be able to get good video for basic operations, but 3d acceleration is probably not going
to happen.
Keep in mind, Linux hardware support is in a rapid state of improvement. If you are not running the
latest version of MEPIS and having hardware troubles, it is highly recommended that you try a newer
27 Some Intel chipset versions, notably the 845 and 965, have known issues with the version of the GUI engine (xorg) included in MEPIS. Check with the community for workarounds if you have one of these. Dual booting issues
Generally speaking, installing an operating system on a computer is simply not an easy task; setting up
two operating systems on your computer is even less so. It involves knowing a bit about hard drives,
file system types, master boot records, and other technical concepts. Setting up your Windows
computer to dual-boot with Linux typically involves doing some things to Windows that Windows was
not designed to sustain. For instance, you will probably have to resize your Windows disk partition,
since in most cases it fills the entire hard drive; or, you might have to overwrite the master boot record
(MBR), which is the part of your hard drive that tells the computer where to find the operating system.
Fortunately, Linux developers have put a lot of work into simplifying and stabilizing the process;
MEPIS boasts one of the most user-friendly installation wizards around. What's more, you can find
some excellent guides to help you install Linux in a variety of scenarios at the “MEPIS guides” website
( Whatever you do, you're strongly recommended to backup all your
important data and programs before installing MEPIS, as the installation process could potentially
destroy your Windows installation28.
Getting help
Built-in documentation
Nearly every command, program, or configuration file in MEPIS has some form of built-in
documentation. Just as in Windows, most graphical programs have a “help” menu with a link to the
program's user manual; this can also be called up by hitting the “F1” key (just as in Windows).
There are a few other methods of getting help, however:
● KDE handbooks: The help files for KDE
programs are referred to as “handbooks”; they are
usually available from the help menu in the
programs, but can also be accessed directly through
the KDE help center (the “help” option on the K
● man pages: man (short for manual) pages are the
most venerable form of help documentation, dating
back to the early days of Unix30. They are generally
used for documenting command line programs,
configuration files, and the command line options of
graphical programs. Man pages can be read at the
command line using the command “man
KDE help center
programName”, or in Konqueror by entering the
address “man:/programName”.
● info pages: info is very similar to man, but is slightly newer and has more features than man.
Even so, it is not as commonly used, and generally if a command has an info page the same text
will be copied into a man page. You can view info pages at the command line with “info
programName”, or in Konqueror by entering the address “info:/programName”.
28 As this statement might alarm some people, it's worth noting that the only truly “dangerous” parts of the install are in resizing the Windows partition and installing the bootloader (GRUB). This danger can be eliminated by adding a second hard drive and doing some special configuration of the Windows bootloader, if you are truly worried about destroying Windows.
29 Occasionally, due to space reasons, programs in MEPIS get installed without their documentation. If you find that a program does not have a “handbook” or help file, try searching in Synaptic for the program, and look for a package of the same name but with “­doc” appended. This package usually contains the help documentation for the package of the same name.

On the Internet
As with most free Linux distributions, the main source of technical support for MEPIS is communitybased and found on the web. The official MEPIS website can be found at;
MepisLovers ( is the community support forum, and LinuxQuestions
( has a forum specifically for MEPIS. The MEPIS documentation wiki,, is a large “online manual” created by volunteers from the MEPIS
community; it has an excellent “Getting Started” section to help newcomers get things up-and-running.
When searching for help on the Internet, keep in mind that MEPIS 6.x is based on Ubuntu Dapper
Drake (6.06), while MEPIS 7.x is based on Debian 4.0 (“Etch”) and many times what is true for
Dapper or Etch, respectively, is true for MEPIS as well. This can be helpful if you're looking for
information about hardware or software compatibility, for example. In a broader sense, Ubuntu itself is
derived from Debian, so often more general advice about Debian can apply to any version of MEPIS.
Be warned, though: given the rapid pace of development in Linux and MEPIS, and some major
changes that took place in MEPIS between the 3.x, 6.x, and 7.x releases, much of the information on
the Internet is outdated or misleading, especially to newcomers. When in doubt, ask on the forums,
where you can get the latest information.
When it comes to asking for help on the forums, you should remember a few important guidelines
about community help:
● Search first: Mepislovers has a good search engine; chances are if you have a common
problem, someone has already posted an answer. In addition, the search feature at
searches the documentation wiki, so a great deal of MEPIS information is readily available; this
should be your first stop for finding answers. Of course, Google can turn up all kinds of
information; Google even has a special search engine for Linux-related topics at
● Be polite, friendly, and positive: Nobody on the forums is paid or obligated to support you; it's
a community. Demanding service from a community forum is like complaining about the food
at a family potluck. Many people like to help newcomers for the pure joy of being helpful and
making use of their knowledge. Be respectful and appreciative of this fact. Also, be aware that
the MEPIS community, unlike some other Linux communities, has historically been more of a
user community than a developer community.
● Be teachable and self-sufficient: Everyone on the community site started out just like you;
over time, they asked questions, read responses, broke things, fixed things, and just generally
got their hands dirty digging-in to what Linux is all about. If you post a problem, you will
probably be asked to run some commands, read some documentation, or check out a post at
another forum. If you aren't willing to learn and do some legwork -- if your expectation is that
someone will wave a magic wand and make your problem go away -- community support
probably isn't for you; you might want to check out a commercially supported Linux, or find
someone in your area (through Craigslist or similar sites) who is willing to do paid support for
● Report back on your results: If you end up finding the solution to an issue, or if the
community manages to get you fixed, make sure you post back saying how the issue was
resolved, and mark your post as “solved”. This helps other people who may be having a similar
problem and are searching the forums for ideas.
What Next?
Hopefully you have taken in more than enough information to get you started using MEPIS Linux. If
you haven't done so already, here are a few recommended steps for getting started with MEPIS:
● Install it! Download the latest MEPIS live CD image from, and install it
on your computer.
● Read the manual: For the release of MEPIS 7.0, the MEPIS user community got together and
produced an excellent, practical guide for installing, configuring, and using MEPIS. You can
find a link to it on your MEPIS 7.0 desktop, or point Konqueror to /usr/share/mepismanual/en/index.html.
● Check out the wiki: Check out the “Getting Started” section on the MEPIS documentation
wiki, Instructions on setting up many common (and some
uncommon) devices and services can be found there, as well as general usage information.
● Join the community: Pop on over to and join the MEPIS
community. You'll find lots of helpful people ready to answer your questions and help you get
productive with your new OS.
● Contribute: MEPIS is free! But if you decide MEPIS is the OS for you, why not contribute
by purchasing items from the MEPIS store at Doing so keeps
MEPIS development going and helps this great distribution to improve.
● Have fun! Tinker, experiment, and explore! MEPIS is loaded with great software and features,
just waiting to be used. See what you can discover!
Thanks for reading, and welcome to MEPIS!
Appendix A: Why open source matters to non­geeks
No introduction to Linux would be complete without a discussion of open-source software and why
open-source, free-as-in-speech31 software is so important. Many new users discount the open nature of
Linux and the programs that run on it, maintaining that there is no practical difference between
proprietary freeware and open-source software. In other words, the fact that it costs nothing is all that
matters. There are several differences, however, that affect ordinary users in major ways.
Granted, most of us (even those with some programming skills) aren't likely to crack open the source
code of our office suite or desktop environment and start hacking around. But consider these
advantages that are unique to open-source:
● Longevity: An open source application will live on as long as anyone takes interest in it. Even
if the company or programmer that started it stops developing it for some reason, anyone else
can pick up the project and keep it going.
● Software meets the needs of all users: As applications develop over time, they sometimes go
through major evolutionary changes. Sometimes these changes don't rest well with all users,
who prefer the old versions. When this happens to an open-source program, the source code
can be forked32 – thus, the old version continues to be developed along a more conservative
vector while the new version can press on more progressively.
● Software works on more platforms: The source code of an application can be compiled to run
on a variety of operating system platforms. An open-source application can be ported to any
platform that users desire, and an open-source operating system can be ported to run on
different hardware platforms (the Linux kernel, for instance, can be run not only on “PC” and
Apple hardware, but on everything from handheld devices to giant mainframes). This means
that you never have to worry about your operating system not working with the software you
like to use. You don't have to buy a new office suite because you upgraded your OS, and you
can run your new OS on your old computer.
● The software will always be free: A piece of proprietary freeware can go commercial any time
the copyright holder wants it to. If the rights to the software get bought by a company, or if the
author just decides to start charging, there is nothing to stop it. Now, there's nothing wrong
with someone charging you for their work, but it's nice to know that your free software will
always be free, and nobody can change that.
● Flexibility and modularity: Open source tends to go hand-in-hand with open standards.
Interoperability and cooperation between developers is a goal of open source software, and
open standards provide a way for developers around the world to create compatible software
without having to work in tight collaboration. For you as a user, this means having options;
when systems are based on open standards, your files will open up in your choice of programs,
your network services will work with your choice of client software, and your hardware will
“just work” on any platform without having to install special driver software. This scenario is
contrary to the goals of many proprietary developers, however, who would rather snare you into
using only their software or hardware.
● Trust: While you may not be scouring the source code of your open-source applications
looking for malicious content, rest assured that many others are. It would be very difficult for a
malicious software author to sneak some spyware or adware into a piece of open-source
software, and it would not go undiscovered for long. Of course, the proprietary freeware world
is chock full of malicious software of all types. Games, media players, utilities and
screensavers have all served as vehicles for malware. Which kitchen would you rather eat food
from: one kept behind locked doors and tinted glass, or one that was out in the open with
nothing to hide?

Security: While it may seem counter-intuitive to some, open-source development methods
generally produce more secure applications. Source code obscurity is often a crutch to make up
for inherent weaknesses in the software's design. After all, if you are assuming that no one will
ever look at your source, you may find it tempting to leave a few things less than secure. On
the other hand, if you know that your source code will be visible to the world, a watertight
design is absolutely necessary.
A second reason why OSS tends to be more secure is that many programmers can look at the
code for flaws and offer fixes. With a closed-source program, only programmers who are
working on the code have the ability to make fixes or find flaws in the programming. Suppose
there are two teams of architects working on plans for a new building. One team only allows
the team members access to the plans. The other team posts its plans on publicly and request
comment from their peers. Who is likely to have a sturdier, safer building in the end?
People who say it better than me...

Appendix B: Distributions
Throughout this article you may have noticed the phrase “distribution of Linux”. This can be a
confusing term and concept for those who are not familiar with open-source software, particularly as
Linux is often compared directly with products like OSX and Microsoft Windows.
Technically speaking, the only part of the Linux operating system that is truly “Linux” is the kernel.
The kernel is the “engine” of the operating system; it's a small layer of software that works directly
with your hardware to perform all the basic operations of your system, such as reading or writing to the
hard drive, moving data to and from RAM, or shutting down all your software when you turn off the
Of course, a kernel isn't much use by itself, any more than a car engine is useful without wheels,
transmission, or chassis. So to create a usable system, the kernel must be bundled together with other
software packages (such as a command-line shell, graphical interface, hardware detection system,
networking subsystem, etc) to create a complete operating system. Any such bundle is referred to as a
“distribution”, or just “distro” for short. MEPIS is one such distribution.
Because the Linux kernel and the software typically bundled with it are free and open-source, any
company, organization, or individual is free to create a distribution and distribute it. They are even free
to take other existing distributions, modify them, and redistribute the result as a new distribution. The
large number of distributions that have resulted from this is often a source of criticism from both
computer novices and industry veterans; indeed, the choices can be overwhelming when trying to settle
on a distribution to use. But keep in mind that this variety is good for Linux and Linux users in many
● It allows Linux to develop in an evolutionary manner, where the best ideas and approaches
garner the most users and interest.
● It allows developers to re-use other good ideas while inventing their own. For instance, by
using the Debian distribution as a base, MEPIS developer Warren Woodford only had to add
the parts that he felt needed improvement in order to create a whole new distribution.
● It allows distributions to specialize. Unlike Windows, which tries to be everything from a
gaming system to a secure server platform in one OS, Linux distributions can be tailored to a
specific niche. For instance, MEPIS and PCLinuxOS are tailored towards home desktop users;
CentOS and RedHat are geared toward secure servers; Knoppix and Morphix are designed to be
useful live CD's; and Musix and Dyne:bolic were designed for multimedia production.
If you want to learn more about the types of Linux distributions available and what sort of features they
offer, a good place to start is
Appendix C: Glossary
binary (file): A file that is computer-readable; usually referring to software that has been compiled, or
to files that cannot be viewed in a text editor. This is often contrasted to “text files” such as ASCII or
Unicode files that are readable in any standard text editor.
command line interface: also known as “console”, “terminal”, “command prompt”, “shell”, or
“BASH”. This is the DOS-style text interface. A root console is one where administrative privileges
have been acquired, either by “su” or by logging in as root.
desktop environment: The software which provides the graphical environment (windows, icons,
desktop, taskbar, etc) for an operating system. MEPIS uses KDE by default.
file system: also “filesystem”. In this case, it refers to the way that files and folders are logically
arranged on a computer's storage devices. It can also refer to the type of formatting on a storage
device, such as NTFS, FAT32, or EXT3. We are using it in the first sense in this article.
fork: This is when two different developers or development teams decide to take a piece of software in
different directions, resulting in two different programs from the same original source code.
free-as-in-speech: The English word “free” has two possible meanings: “without cost” and “without
restrictions”. In the open-source software community, the usual analogy used to explain the difference
is “free as in beer” vs. “free as in speech”. The word “freeware” is used to refer to software that is
simply without cost, whereas the phrase “free software” typically refers to software which is open
source and licensed with some type of open license (such as the GPL).
GPL: The GNU General Public License. This is the license under which Linux and many open source
applications are released. In a nutshell, it specifies that you may view, modify, and redistribute the
source code of applications released under it, within certain limits. The complete GPL can be found at
GUI: Graphical User Interface. This refers to a program or operating system interface that uses
pictures (icons, windows, etc), as opposed to text-mode (command-line) interfaces.
kernel: The layer of software in an operating system that deals directly with the hardware.
live CD: A bootable compact disc from which one can run a full operating system, usually with a
complete desktop environment, applications, and essential hardware functionality.
open-source: Software whose source code has been made available to the public. It also implies some
kind of unrestricted licensing.
script: An executable text file, containing commands in an interpreted language. Usually refers to
BASH scripts, but other languages can be used as well.
source code: The human-readable code in which software is written.
tarball: An archiving format, like zip, popular on the Linux platform. Unlike zip files, though,
tarballs may use one of a number of different compression formats, such as gzip or bzip2. They usually
end in file extensions like .tgz, .tar.gz, or .tar.bz2.
window manager: A component of a desktop environment that provides the basic
maximize/minimize/close/move functions for windows in the GUI environment. Sometimes they can
be used as an alternative to a full desktop environment.
Unix: (also UNIX) The operating system which Linux is modeled after, developed in the late 1960's at
Bell Labs and used primarily for servers and mainframes. Like Linux, Unix has many variations; for
more information, see this article:
X: also X11, X windows, xorg. The basic GUI engine for most Linux and Unix systems.
