OK, ATI driver 8.29.6 is buggy for some video cards.
Then I tried to install dirver 8.28.8, but the installation
process fails with my kernel version 2.6.18...
Did anyone install ATI driver 8.28.8 with kernel 2.6.18 ? :|
Did anyone installed successfully the native Mesa driver r300
with kernel 2.6.x ? :|
Thank you all
