I use an ATI card. The standard 'ati' opensource drivers don't cooperate- I have to use FGLRX. Using the restricted drivers manager made installing the drivers easier, but I still needed to configure them, specifically:
sudo gedit /etc/X11/xorg.confThese steps were -essential-. When I was having problems getting this stuff to work I initially went straight to Google for answers which led me in circles for a long time. I should I have stuck to the basics!
and addingSection "Extensions"Followed by:
Option "Composite" "Disable"
sudo aticonfig --initial
sudo aticonfig --overlay-type=Xv
Check http://wiki.cchtml.com/index.php/Ubuntu_Feisty_Installation_Guide before doing anything else!
The second culprit was the newest Beryl version, 2.1.0. This was something I didn't know about until I found myself at this thread at the Ubuntu forums.
Ubuntu forum member Eode details how to escape the 2.1.0 trap and use version 2.0.0 of Beryl, which fixed all of my Beryl problems.
