Problem with intel driver on laptop with 945GM chipset

I think I solved the problem.

It was all about gamma correction settings in xfce4 :-)

I came to this idea when I saw that gdm which I recently installed, 
displays fine.

When I checked gamma settings, all sliders were full down to the 0.10 
value, instead of 1.00. Do you think it's xfce's bug or intel's? Why 
with vesa drivers the gamma was ok?

The AIGLX error is also no longer existant, because I use the driver 
from Debian repositories.
