I have installed Ubuntu 11.10 successfully and everything works perfectly except the fan, it is working constantly and it has nothing to do with the CPU because if I don't open any programs it will remain at high speed.
I figured it may be because of AMD/ATI, I tried different ways of installing it manually and even automatically via Ubuntu itself but never worked!
Is there a (basic if possible) way of fixing this? Maybe controlling the fan speed would do the trick.
