--- Comment #3 from Denis Washington denisw@online.de 2011-04-05 13:30:30 --- I am aware of the power management options you pointed to, but they don't help with the fan problem (at best, they delay it slightly). /sys/class/thermal does not contain any thermal zones, there are only two CPU-related cooling devices and an LCD cooling device listed there:
$ ls /sys/class/thermal cooling_device0 cooling_device1 cooling_device2 $ cat /sys/class/thermal/cooling_device0/type Processor $ cat /sys/class/thermal/cooling_device0/device/path _PR_.CPU0 $ cat /sys/class/thermal/cooling_device1/type Processor $ cat /sys/class/thermal/cooling_device1/device/path _PR_.CPU1 $ cat /sys/class/thermal/cooling_device2/type LCD $ cat /sys/class/thermal/cooling_device2/device/path _SB_.PCI0.P0P2.VGA_.LCD_
Does that mean it is an OEM-specific sensor? Why is it that fglrx can control the fan just fine then? (Or does fglrx have code specific to certain hardware vendors?) How I can find out more about how the GPU fan is controlled with this laptop?
