So the problem is...every time I reboot or shutdown laptop and when the laptop is booting again I get screen (before loading OS) that HP discovered overheating and system went into hibernate. But the point is that laptop is not overheating nor going into hibernate by itself. Also becouse of the hybrid graphic cards 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 docks) As i've read some posts, people say that switcheero doesn't work on 12.04 so I haven't tried it.
