I installed Unity on my Belinea o.book 13011. Now there are four Tasks named kslowd000 to kslowd003. Each task uses 10-15% CPU, expect there is another Task that needs more.

So the CPU Fan is running continously. How can I fix that?

There seem to be several bug reports about this in the 2.6.35 kernel (the one that's included in Ubuntu 10.10).

Edit:

These are (some of?) the kernel bugs involved:

It seems like there is a workaround, but it doesn't always work (automatically).

You can try to see if the following helps:

sudo -c sh "echo N > /sys/module/drm_kms_helper/parameters/poll"

damn, will this be fixed in 10.10? –  burli Oct 31 '10 at 8:16
    
I have the bug, but I have no '/sys/module/drm_kms_helper/parameters' so I cannot try the fix... –  Huygens Dec 19 '10 at 14:29
