How I can uninstall or reinstall my Radeon 7500 driver? Also, can I try a different Xorg version? My T40 (Thinkpad) is not getting 3D acceleration on Ubuntu 11.10. What is the best Ubuntu version if I want to enable effects in Compiz (like wobbling windows)?
I am not an advanced Linux user, but I have used Fedora, so I have a bit of experience. I no longer use Windows, unless I am using FruityLoops.
