I have a HP G62 with an ATI Mobility Radeon HD 5470 graphics card. Back when I was using Ubuntu 10.04 I tried to install the Catalyst drivers and probably other ones too but could not get them working. I would, in the end, end up with blank screens all the time. So I gave up and did not install any drivers (I am also not the only one with the problem: http://ubuntuforums.org/showthread.php?p=8972359, and I have tried everything in the thread).
When I rung sensors in the console I get
sensors acpitz-virtual-0 Adapter: Virtual device temp1: +68.0°C (crit = +90.0°C) radeon-pci-0100 Adapter: PCI adapter temp1: +84.5°C
As you can see the graphics card is getting too hot. What can I do about this?
Everything works fine under windows 7 (64bit). I don't know the temp but I can feel and hear the difference (it is much cooler and the fan does not work that much).
