I think, but im not sure, that the ati driver is loaded, if X was started.

Can you clarify, please?dann Well, i see it looks a little bit confused what i wrote. What i mean is= , that the fan at this time starts to rotate, when the "radeon display support" is loaded at boot time. Normally the fan should start to work if a special temperature threshold is reached.=20 >=20 > > Here you see the difference between 2.6.21, when it all works corre= ctly, and > > 2.6.22 and 2.6.23: the screen resolution of the boot screen changed= to > > the native resolution 1024x768 (in 2.6.21 it still the default term= inal > > resolution)=20 >=20 > This only means that the kernel's radeon driver has changed. >=20 > It's difficult to say what's going wrong. >=20 > What's the CPU load when the fan is spinning? >=20 > Greetings, > Rafael The rest of the systems works fine.
