I am inclined to believe that these Linux distributions are more or less compatible, i.e. programs that work well in one may work as well with the other. Perhaps this is because both were derived from Debian, one of the older Linux distributions.

Thus, most of the instructions here about Asus EEE may probably also work for Ubuntu, the same way that Ubuntu forums helped me in doing Asus EEE Xandros stuff.

1. Launch Console.

2. Enter sudo apt-get install msttcorefonts.

Note: Update first the list of packages by adding the Xandros repositories to sources.list and invoking apt-get update. (See previous post: LaTeX 1.1)

Reference:
http://ubuntu.wordpress.com/2005/09/09/installing-microsoft-fonts

1. Launch Console. (Hotkey Ctrl+Alt+T in Easy Mode)

2. Enter “sudo bash“. This gives us Admin privileges.

3. Enter “nano /etc/apt/sources.list” and

4. Add the following Xandros repositories after the default two lines of the list of sources:

deb http://download.tuxfamily.org/eeepcrepos p701 main etch
deb http://xnv4.xandros.com/xs2.0/upkg-srv2 etch main contrib non-free
deb http://dccamirror.xandros.com/dccri/ dccri-3.0 main
deb http://www.geekconnection.org/ xandros4 main

* Note: The spaces are really included.

5. Save by Ctrl+O. Exit/Return to main command line by Ctrl+X.

6. Enter “apt-get update“. This updates the list of packages from the repositories.

* Note: This requires Internet connection. And so will all other apt-get processes.

* Note2: In the event that the update process will not be completed, probably due to poor connection, we may update the repositories one-by-one. We do this by slightly modifying the sources.list file every time, leaving only one line by commenting out the rest with ‘#’, and then applying “apt-get update” for that. An example:

#deb http://update.eeepc.asus.com/p701 p701 main
#deb http://update.eeepc.asus.com/en p701 main
deb http://download.tuxfamily.org/eeepcrepos p701 main etch
#deb http://xnv4.xandros.com/xs2.0/upkg-srv2 etch main contrib non-free
#deb http://dccamirror.xandros.com/dccri/ dccri-3.0 main
#deb http://www.geekconnection.org/ xandros4 main

* Note3: We may get the error “NO_PUBKEY”. To get the key for download.tuxfamily.org, enter “wget http://download.tuxfamily.org/eeepcrepos/key.asc” then enter “apt-key add key.asc”. This is actually optional. Also, for xnv4.xandros.com, this does not work.

7. Enter “apt-get install tetex-base“. Key in ‘y’ when prompted.

8. Enter “apt-get install tetex-bin“. Same.

9. If we need to use the beamer class/package, enter “apt-get install latex-beamer“. Otherwise, we’re done.

10. Another optional package is Texmaker, a free Latex editor. Similarly, we install this by entering “apt-get install texmaker“. Texmaker can be launched from Console by simply entering “texmaker“.
