Desktop effects with Ubuntu 7.10 (Gutsy Gibbon)

I wanted to try out the new desktop effect features of Ubuntu Gutsy but i got the following error message:

Desktop effects could not be enabled

So i started compiz from shell to see a possible error message. I found this message:

Checking for Xgl: not present.

I thought that Ubuntu already installed all packages i needed to run compiz, but it seems like i had no XGL installed.
So i started aptitude, searched for "xgl", found "xserver-xgl" and installed it.

You can do that by using aptitude directly from shell:

sudo aptitude install xserver-xgl

Now restart X (ALT + CTRL + Backspace), login again and enable the desktop effects! It does work without any modifications to your xorg.conf because Ubuntu did that for you after installing xserver-xgl.

Have fun! :)

My keyboard layout was changed after the restart of X. You can easily change it to your preferred keyboard layout in the Ubuntu settings menu.
