I get this after installing ati drivers with the installer:
[root@localhost installid]# fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.2.1)
I didn't notice that those drivers doesn't work with FC4's kernel.
I would uninstall installed drivers and do like Seehund suggested, but I don't find anywhere how to uninstall ati drivers that have been installed with the installer. Any suggestions?
