Every time I reboot or shutdown my laptop, while the laptop is booting again I get a screen (before loading the OS) that HP discovered overheating and system went into hibernation. But the point is that the laptop is not overheating nor going into hibernation by itself.

Also, because of the hybrid graphics card I cannot install additional drivers. Desktop resolution and all works perfectly but I cannot use Unity 3D. Also, OpenGL doesn't work as it should (with Cairo Dock).

As I've read some posts, people say that vgaswitcheroo doesn't work on 12.04 so I haven't tried it.

Thanks for your replies ! CPU: intel i3, graphic: intel intergrated and radeon HD 6470m. It is HP Pavilion g6 1190sm (1190sm i belive is a model just in Slovenia. As I haven't noticed anywhere else (on google) that this model would be somewhere else in Europe or USA. It also might be good idea if I would update my BIOS as I have installed windows 7 back again. –  Jan May 31 '12 at 18:04
