Hi Hans, so the radeon driver seems to work but maybe needs some tweaking.
1) Let's have a look at Xorg.0.log. grep -i chipset /var/log/Xorg.0.log grep -i render /var/log/Xorg.0.log (Maybe, append the file to your message) 2) Is there a file /etc/X11/xorg.conf? 3) Take a look at the man-page of "radeon" (man radeon) Regards, jvp.
