11 ubuntu derivatives

On this site I found a list of 10 derivatives.
http://digitizor.com/2009/09/05/10-best-derivatives-of-ubuntu/

I added an eleventh:

1. Kubuntu
Of all the Ubuntu derivatives, Kubuntu is perhaps the most popular. It is maintained by Canonical, the same company behind Ubuntu. Kubuntu uses KDE as the graphical environment instead of GNOME which is used in Ubuntu. It follows the same release cycle as Ubuntu.

Download: How Can You Get Kubuntu? Kubuntu
2. Xubuntu
Xubuntu is also another Canonical Project. In Xubuntu, the graphical environment used is Xfce in place of GNOME. It is a distribution meant for systems with limited (read lesser) system resources. Xubuntu also follows the Ubuntu release cycle.
Website: Xubuntu Home Page Xubuntu
Download: Get Xubuntu Xubuntu
3. Edubuntu
Edubuntu is yet another Canonical maintained derivative of Ubuntu. Unlike the previous two distributions, it does not use another graphical environment. It uses GNOME, same as in Ubuntu. Rather, Edubuntu is Ubuntu for students and teachers and has been enhanced with educational tools and applications. And yes it also follows the Ubuntu release cycle.

Download: Download Edubuntu edubuntu
4. Ubuntu Studio
Ubuntu Studio is an Ubuntu distribution which is meant for multimedia production. It is an officially recognised Ubuntu distribution. It includes a Linux kernel which has been modified for graphical, audio and video works. Unlike other Ubuntu distributions, it does not fit in a CD and comes in a DVD.

Download: Downloads Ubuntu Studio
5. nUbuntu
nUbuntu is a remastered version of Ubuntu for security testing. It combines the ease of use of ubuntu with a host of tools necessary for penetration testing of servers and networks. It is not a Canonical supported project. Its latest version is 8.12 which is in beta stage.
Website: nUbuntu
Download: nUbuntu – Download
6. Linux Mint
Linux Mint is another non-Canonical supported derivative of Ubuntu. Like Ubuntu, Linux Mint also uses GNOME as its default graphical environment but its interface has a distinct look from Ubuntu unlike other distributions mentioned here. It also comes with media codecs which are excluded with the default Ubuntu installation. Linux Mint also comes with variations with KDE and Xfce also.
Website: Linux Mint Main Page
Download: Linux Mint Download
7. Super OS
Super OS, formerly known as Super Ubuntu, is a remastered version of Ubuntu. It contains various enhancements over Ubuntu while still remaining compatible with it. It is prepackaged with mp3 and video-DVDs support.
Website: Super OS
8. Poseidon Linux
Poseidon Linux is a Ubuntu 8.04 LTS based OS which is mainly meant for scientists. It contains many free softwares used for scientific analysis like 2D/3D/4D, statistical tools, mapping tools etc. Originally created in Portugese language, it has now been extended to many languages due to its popularity among the scientific community.

9. Mythbuntu
Mythbuntu is a media center OS based on Ubuntu and has the MythTV Media Center Software as its main function. It uses Xfce graphical environment by default although other environments can also be installed. Although not a Canonical supported product, it follows the Ubuntu release cycle very closely.

10. Ubuntu Netbook Remix
Ubuntu Netbook Remix is a collaborative effort between Canonical and Moblin Project to optimise Ubuntu for netbook usage, i.e. lower hardware requirements, longer battery life and better display on smaller screen. There are also variants of Ubuntu Netbook remix which are made for certain netbook vendors.

11. OpenGEU
OpenGEU, previously known as Geubuntu, is a complete and fully functional Operative System based on the popular Linux Distribution Ubuntu. OpenGEU, a project started and designed by the Italian artist Luca D.M. (aka TheDarkMaster), is perfect for any Desktop, Laptop PC or even for a Virtual Machine. OpenGEU mixes the power and simplicity of Ubuntu and parts of the Gnome Desktop with the wonder and astonishing eye-candy of Enlightenment DR17.

NVIDIA troubles with legacy card

Issues I had to install my graphic card in linux Mint and in Ubuntu -Nvidia Rivia TNT2-

(On the Ubuntusite a very good article about Xrandr)

I can tell you installing the "right" driver for your graphic will boost your Ubuntu speed and also its appearance and it really becomes faster !

First of all I make a back up of my Xorg.conf like a good boy !
So here is how I installed my Nvidia TNT2 graphic card :
I first backed up my Xorg.conf using this command (you should really do that before installing any graphic driver program )
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
then I installed the driver using the menu , system--> adminstrator --> restricted driver manager ,then it automatically installed my graphic card.


How to make sure if the Graphic driver is installed and enabled ?

try this in a Terminal
sudo nvidia-glx-config enable
and also this :
glxgears
this should show a 3D animation and also some numbers in the terminal like

1100 frames in 5.0 seconds = 219.997 FPS
1384 frames in 5.0 seconds = 276.788 FPS
1385 frames in 5.0 seconds = 276.896 FPS
1385 frames in 5.0 seconds = 276.849 FPS
1382 frames in 5.0 seconds = 276.397 FPS

if those numbers which I marked in red, are less than 1000 (like 150 , 300...) then you have not enabled / installed it right !

Ah , Low Screen Reolution Problem !
but after installing I found out my screen resolution is 800*600 and it doesn't let me change it . some others also have the same problem , and a bug is listed in launch pad for this !

the problem is the Ubuntu fails to detect the monitor Horizontal and Vertical Refresh Rate numbers, (on Ubuntu site they have explained this fix in detail) .
to fix this problem I do this (I have made backup of the xorg.conf ! okay?)
sudo gedit /etc/X11/xorg.conf
(if you are in not graphic mode , you should use nano instead of gedit)

now find the Section "Monitor"
and add these lines just before EndSection :
HorizSync 30-96
VertRefresh 50-160

mind that those numbers (30-96 and 50-160) are default numbers which should work with most monitors ,but your monitor may be different , so google for it to find the right numbers.
for your own monitor .

now save the file and then restart your Ubuntu !

If you messed up your graphic in Ubuntu...
You no longer see any graphic but a black page with terminal (command prompt) ?
Don't get scared (terminal is not gonna bite you) , it is easy to recover , fix everything using commands .
cd /etc/X11/
Then
dir
this shows list of files in that folder
mv xorg.conf.backup xorg.conf
If your backup file name is different change xorg.conf.backup , for example
mv xorg.conf.backup20070404 xorg.conf

To find out the name of the back up file just look at the list of files which "dir" command gave you.

uninstall

I use Linux Mint because the system doesn't get corrupted by installing a lot of programms. Sometimes I need MS Windows. I still use XP. Now I found this uninstall programm:

Allmyapps

A new website to be used for installing apps in Ubuntu and mint

Allmyapps
I quote fullcircle magazine page 21:

I get frustrated each time an iPhone owner talks about how cool the Apple AppStore is. Technically, the Apple AppStore is nothing but a package repository like those we've enjoyed for ages in the Linux world! Our goal is to unleash the true power of Linux package repositories, and show it to the world. With allmyapps, we want to give users the best
application installation tool in terms of eyecandy and usability. Indeed, allmyapps
leverages on the power and the depth of our package repositories to provide users
with a tool that is fun, easy, and, of course, secure! We have tried to make allmyapps
visually appealing, so that people will enjoy browsing applications on it. In the same
spirit, we have also focused a lot on usability to help people find the applications they need,
either by browsing categories or by performing a free search. Finally, as allmyapps relies on
the apt package management system (through apt-url), it is completely safe for users to
use. A lot of people asked us why we decided to implement allmyapps as a Web application
and not as a traditional desktop application. The main reason is that we want
allmyapps to be visible to all users (not only Linux users). This is also why, beyond
traditional social features like screenshots, reviews, and ratings, allmyapps gives you
the ability to create lists of applications that you can share with others via email or a Web
widget. The goal here is to help spread the word and make people realize how easy and
fun it is to install applications on Linux!

ten ubuntu related sites

On maketecheasier I found these links:

1) Ubuntuforums

Needless to say, the best place to go for Ubuntu support is none other than the popular Ubuntu Forums. This is the only place where you can find all kind of advices, tips and tricks, hacks and solutions related to Ubuntu. If there is a Ubuntu-related problem that you can’t solve, most likely it has already been discussed in the forums. Simply do a search in the forums or post your question and you will receive plenty of help from the community.

2) Ubuntu Guide

As its name implies, UbuntuGuide is a wiki where you can find plenty of guide, tips and tricks for Ubuntu. It covers information from Ubuntu Dapper to Jaunty and is available in multiple languages. While UbuntuForums is a great means to get solutions for your problems, UbuntuGuide is the place to go to find new tricks and apply them in your system.

3) Ubuntu Hardware Support List

While Ubuntu supports a wide range of devices, there are still times when you can’t get a particular hardware to work. The Hardware Support page shows a hardware compatibility list that you can refer to before you make any hardware purchase. This hardware support page is maintained by the community and anyone can add/modify the entry.

4) Ubuntu Documentation

It is no doubt that Ubuntu is an easy to use and user-friendly distro. However, if you are still having difficulties navigating around and get it to perform simple daily tasks, you can head on to Ubuntu Documentation and read about everything you need to know about Ubuntu. It won’t make you an expert, but at least it can help you to get started (and perhaps show your friends how geeky you are).

5) Launchpad

Launchpad is the place for you to discover new open-source applications or retrieve source code/installation instruction for third party apps that are not found in the Ubuntu repositories.

6) Gnome-look.org

If you love eye-candy, beautiful wallpapers, login screen, splash screen and everything about your Ubuntu system, then gnome-look.org is the place to visit. It contains a great collection of artworks and themes contributed by the community. They are free to download and use.

Kubuntu and Xubuntu users can check out kde-look.org and xfce-look.org respectively.

7) Ubuntu Brainstorm

Ubuntu Brainstorm is a Digg-like site where you can submit your ideas/suggestions/stuffs to be included in future version of Ubuntu and let others vote for it. Popular ideas (those that received a lot of votes) are reviewed by the Ubuntu team and possibly include them in the future release.

8) Full Circle Magazine

Full Circle Magazine is the only website that is dedicated to publish a free Ubuntu magazine (in pdf format) every month. Being a loyal subscriber, I have found their magazines very informative, yet doesn’t get too technical in detail. It is great for new users who wanted to learn more about Ubuntu.

9) Ubuntu Seach Engine

A Google custom search engine dedicated to search only Ubuntu-related stuffs. Currently it indexes 169 Ubuntu-related sites, including UbuntuForums, Ubuntu Wiki and Ubuntu Guide.

Other dedicated Ubuntu search engine that you can go to include Ubuntu-Search and Ubuntu Wire.

10) Planet Ubuntu

Planet Ubuntu is a blog written and updated regularly by Ubuntu developers and contributors. This is where you can get the latest and updated news about your system.
