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?
Just got it working here (Ubuntu 12.04 64-bit) for the first time since I bought this damn HP Pavilion 4045ea.
I removed every single iteration of fglrx, installed the ATI binary driver from the Software Centre, rebooted and ta-daa!
Unity looks better, full HD movies are finally playable and the whole system seems to be running better.
