Hi all!

I'm having some trouble with this Laptop: HP pavilion g6 1364sl

Intel i5 2450M
ATI radeon 6400(6450 maybe)M
Intel HD 3000
Ram 4GB

Running ubuntu 12.04 up to date.

Well, I finally succeded in turning off ati video card (or at least that's what ubuntu says):


Code:
sudo cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Off:0000:01:00.0
and:


Code:
lspci -vnnn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Seymour [Radeon HD 6400M Series] [1002:6760] (rev ff) (prog-if ff)
According to the instructions I found on the net, this should mean that discrete card is turned off.

If i check GPU temperature with sensors

Code:
radeon-pci-0100
Adapter: PCI adapter
