Hi, thanks for the tip.
I do wonder, as the machine started to get hot after an upgrade through apt. I guess there is a lib file out there that makes it hot. I am using ACPI off, which means, in my understanding that linux is not involved in the temperature control, the BIOS manages it by itself. So I do not understand, how an upper layer SW can block the BIOS from managing.
I am not using my laptop for that advanced graphics, just Compiz and cube, and I have not noticed any benefit with fglrx driver.
