Default Cannot overclock laptop graphics card


I'm struggling to overclock my 8600m GT in Linux Mint (Ubuntu derivative)...

I've enabled Coolbits but auto detect is greyed out in the X Server Settings, also when I manually change the settings it immediately defaults back.

Is GPU overclocking of laptops disabled on Linux? As I was previously able to with Windows?

I'm using the 256.35 drivers.

Also Nvclock will not adjust settings.

I can however software overclock in Windows, and I suppose if push comes to shove use NiBiTor but i'd prefer not to do this for fear of bricking it!

Any assistance greatly appreciated.

Thanks, Chris.

What you observe is "normal" for both nvidia-settings and nvclock. I don't remember anyone ever managing to software OC a mobile linux system.

For most people that's probably ok since if you really need that last bit of performance it's usually for a windows game...
