So what's this Linux thing all about? What does Linux look like? What software
runs on Linux?

## What is Linux about?
2024-04-03 00:08:31 -07:00
You can find a good introduction to Linux [here](https://www.geeksforgeeks.org/introduction-to-linux-operating-system/).

## What does Linux look like?
2024-04-03 22:37:44 -07:00
Over the last few years, Linux graphic user interfaces (GUI) have greatly
improved. Click to view screenshots of the current desktop environments offered
by the Gnome and KDE Project.

## How about software?
2024-04-03 22:37:44 -07:00
There is a large selection of software for Linux. For quick selection and
comparison, see the fossfor.us site.
2022-10-03 20:27:19 -07:00
2024-04-03 22:37:44 -07:00
According to [freshmeat.net](https://freshmeat.net) (a large index of software
for Linux and other Unices), there are currently over 23,000 projects in
development. Many of these programs are Open Source and/or free.

## Getting Linux
2024-04-03 22:37:44 -07:00
Interested in trying out Linux? Our Getting started page will step you though
the process of finding, installing, and tweaking Linux on your computer.
2022-10-03 20:27:19 -07:00
Installing Linux can sometimes be difficult, but the LUG is here to help!
1. back up all your data (see page on backups)
2. pick a distribution
3. decide if you want to dual boot with Windows/Mac or just overwrite everything
4. install it:
- come to quarterly installfest
- stop by the lounge any time and somebody might help
- do it yourself!
## Distros
2024-04-03 22:37:44 -07:00
Choosing a distribution can be challenging! (Though it actually matters less
than you think.)
2022-10-03 20:27:19 -07:00
2024-04-03 22:37:44 -07:00
Here's a short and incomplete list to help you choose:
2022-10-03 20:27:19 -07:00
2024-04-03 22:37:44 -07:00

## Tips for selecting a distro
2024-04-03 22:37:44 -07:00
If you are a beginner and you don't want to mess with the terminal that much,
choose a Debian based one like Mint. Most of the Debian ones just work straight
out of the box. There's also tons of support.
2022-10-03 20:27:19 -07:00
2024-04-03 22:37:44 -07:00
If you have some experience (or you're a beginner who is fine with using the
terminal), you can try one of the Arch-based distributions. Installing Arch
takes a while, but it's actually not too hard. If you're too lazy to install
Arch, choose a distribution with a graphical installer (like EndeavourOS).
2022-10-03 20:27:19 -07:00
Here's a quiz you can try: https://distrochooser.de/en/
## Comparing Arch and Debian
2024-04-03 22:37:44 -07:00
Choose Arch-based distributions if you want a minimal distribution. Choose
Debian based distributions if you want stability or ease of use.
2022-10-03 20:27:19 -07:00
# Desktop Environment
2024-04-03 22:37:44 -07:00
The **desktop environment** (DE) is what makes up most of the user interface. It
may include system panels, docks, window borders, backgrounds, and desktop
widgets, among other things. GNU/Linux has a wide variety of DEs avaliable—this
page will outline some of the most popular ones.
2022-10-03 20:27:19 -07:00
2024-04-03 22:37:44 -07:00
It is important to note that no DE is tied to a particular GNU/Linux
distribution, or vice versa. Thus, if your distribution of choice is Debian,
you may use GNOME, or KDE, or both GNOME and KDE (if you installed both). You
can install as many different DEs as you want and try them all!
2022-10-03 20:27:19 -07:00
The three main desktop environments are XFCE, KDE, and GNOME.
2024-04-03 22:37:44 -07:00
* **XFCE:** XFCE is designed to be fast and minimalist
* **GNOME:** GNOME is simpler to use, and looks nicer. Of course, this comes at the cost of performance (the difference isn't that much though).
* **KDE:** KDE is in between GNOME and XFCE in terms of performance and features. If you are unsure, KDE is a good choice.
2022-10-03 20:27:19 -07:00
### Tiling windows managers:
2024-04-03 22:37:44 -07:00
Tiling window managers are a lot more difficult to use, and aren't for
beginners. Navigation is usually done using the keyboard as opposed to the
mouse.
2022-10-03 20:27:19 -07:00
## FOSS Software
2024-04-03 22:37:44 -07:00

### Office Suite - LibreOffice
2024-04-03 22:37:44 -07:00
LibreOffice is a free and open source office suite. It includes key office
applications such as a word processor, spreadsheet, presentation manager, and
drawing program, all with a user interface and feature set similar to other
office suites.
2022-10-03 20:27:19 -07:00
2024-04-03 22:37:44 -07:00
Sophisticated and flexible, LibreOffice also works transparently with a variety
of file formats, including those of Microsoft Office. It primarily supports the
Open Document Formats (ODF), such as .odt (documents), .ods (spreadsheets), and
.odp (presentations). Here at the LUG, these are the formats we primarily use.
Also, many European governments are adopting ODF as the official format for
electronic documents. ODF and LibreOffice promotes total interoperability and
information integrity.

### Audio Player - VLC, MPlayer, Clementine
2024-04-03 22:37:44 -07:00
VLC is famously known as the player that "plays everything." It can handle
DVDs, (S)VCDs, Audio CDs, web streams, TV cards and much more. You don't need to
keep track of a dozen codec packs you need to have installed. VLC has nearly
all codecs built-in. It can even play the file or media if it is damaged!
2022-10-03 20:27:19 -07:00

### Movie Player - MPlayer, VLC
2024-04-03 22:37:44 -07:00
MPlayer is a movie player for Linux. It plays most MPEG, VOB, AVI, VIVO,
ASF/WMV, QT/MOV, FLI, NuppelVideo, yuv4mpeg, FILM, RoQ, and OGG files, and some
files for RealMedia. You can watch VideoCD, SVCD, DVD, 3ivx, FLI, and even DivX
movies too.
2022-10-03 20:27:19 -07:00
2024-04-03 22:37:44 -07:00
Another big feature of MPlayer is the wide range of supported output drivers.
MPlayer supports displaying through a number of hardware MPEG decoder boards
such as the DVB and DXR3/Hollywood+ . And what about nice, big anti-aliased
shaded subtitles (9 supported types!!!) with european/ISO 8859-1,2 (hungarian,
english, czech, etc), cyrillic, korean fonts, and OSD.

project. It is suitable for tasks such as photo retouching, image composition,
image authoring, or any other task that requires manipulation of raster images.
2022-10-03 20:27:19 -07:00
Inkscape is a professional *vector* image manipulation/creation program.

GCC provides many levels of source code error checking traditionally provided
by other tools (such as lint), produces debugging information, and can perform
many different optimizations to the resulting object code.
