Comment 1 for bug 372024

I have a similar problem on my Acer Aspire 2920 with intel video card. The fan runs permanently. I don't have installed tracker but I have downgraded my intel driver to 2.4: https://wiki.edubuntu.org/ReinhardTartler/X/RevertingIntelDriverTo2.4 because I didn't have the problem with Intrepid Ibex. Nothing worked. The fan still runs permanently.

My harddisk gots a little bit too warm:

$ sudo hddtemp /dev/sda
/dev/sda: WDC WD3200BEVT-22ZCT0: 56°C
$ sudo acpi -t
     Battery 0: Full, 100%
     Thermal 0: ok, 43.0 degrees C
     Thermal 1: ok, 45.0 degrees C

Top shows mainly xorg and firefox on the top:
