I have a laptop with freshly installed Ubuntu 11.10 and ATI 4200/AMD Radeon 5650 hybrid graphics. The problem is that I can't switch between integrated and discrete video while using Catalyst driver (ver 12.2). Catalyst tells me that I can switch on to discrete on next reboot but after that, the laptop still uses integrated video.
Additionally, my whole system is very slow when I'm using the Catalyst driver.
How can I solve this problem?
