http://ubuntuforums.org – As I remember, all the time, after fresh-installing Ubuntu on my HP ProBook 4530s, the Radeon graphics doesn't work, it uses Intel Sandybridge Mobile instead. The point is, that the required driver packages are already installed, but system uses the Intel driver anyway. Driver packages installed: Code: xserver-xorg-video-ati xserver-xorg-video-radeon xserver-xorg-video-vesa xserver-xorg-video-intel xserver-xorg-video-all I was using the proprietary Catalyst driver until today and it was very buggy! Many GTK apps were crashing, Compiz was crashing, even session was crashing when tryin (Hardware)
