How to disable 2nd graphic card?

Weri · 2011-02-02 19:20:37

I have a laptop Sony VGN-Z21XN/B with two graphic cards:

1) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
2) 01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 9300M GS] (rev a1)

Unfortunately both are running at the same time so my laptop is hot, noisy and the battery is discharged very soon. Is there any possibility how to permanently disable nVidia graphic card somewhere in system? I already tried disable nVidia modules in rc.conf, but without result and google doesn't help

Thank for advice.

for switchable gpu laptops, there may or may not be a setting in the bios to disable the nvidia gpu. If you fall under the latter, you are just plain out of luck.

Check your BIOS to see if you can disable the GPU.

Look here: http://linux-hybrid-graphics.blogspot.com/, maybe someone has figured out how to shut down the nvidia card for your particular laptop. Or maybe one of the generic methods described there will work. It's too bad this whole Optimus thing is such a mess. It really tarnishes the reputation nvidia had with Linux.

I've just checked my bios settings and there is no option to set or disable graphic card. Bios is actually very poor.

The problem is that sony provides only windows (vista and 7, not XP) software switch so there is no HW support for switching... I am looking for something like disable hardware in windows device manager. Simply tell arch: don't use that stupid piece of crap...

However I'll have a look to site that you posted
