I have a problem with switching between integrated Radeon 4200 and discrete Radeon 6600M (actually Radeon 6650M) on HP Pavilion dv6-6030er. In Win7 it is working properly, but in Debian GNU/Linux (testing) it doesn't work. Installed fglrx 11.6 (from unstable repository). There is an option in ATI Catalyst Control Center (amdccle) to switch between cards. It can be changed (and it asks to reboot), but after reboot or Xorg restart it returns back.
My lspci -nn: http://pastebin.com/VBWa10mt
My xorg.conf (created with aticonfig --initial): http://pastebin.com/ZkezxQ8H
My Xorg.0.log: http://pastebin.com/HCV6H9Um
Also I tried to change
in my xorg.conf to
(see my lspci -nn output). But after that I got segmentation fault: http://pastebin.com/6psjDc8S
Using Debian GNU/Linux testing.
Linux kernel: 2.6.39+35.1
AFAIK 6600m is muxless card
