I ran into a problem with a new install of ubuntu 11.04 on a panasonic toughbook cf-18.
Compiz was not working so I created a xorg.conf file using "X -configure".
Now I do have the 3D effects but the screen flickering and tearing is so bad I can't use it.
Does anyone know how to fix this problem? Let me know if you need any specs from the laptop.
