Ok, so I've got the 5650 as a discrete gpu and integrated 4200. The problem is that I cant switch to 5650. fglrxinfo shows that 4200 is on, but aticonfig -px-list shows that Discrete GPU is active.
lspci shows this:
01:05.0 VGA compatible controller : ATI Technologies Inc M880G [Mobility Radeon HD 4200] [1002:9712]
02:00.0 VGA compatible controller : ATI Technologies Inc Madison [AMD Radeon HD 5000M Series] [1002:68c1] (rev ff)
as xorg looks like this:
xorg device section:
I thought that if I change busid to PCI:2:0:0 it'll help, but it won't. looks like ubuntu can't see 5650 as with PCI:2:0:0 I cant run X. any suggestions what to do?
Also I can't disable 4200 in BIOS
