----- Original Message ----- | I did. But no improvement. Check to see that /etc/X11/xorg.conf contains a fglrx line. If not run aticonfig --initial as root on the command line and restart X. That should configure the driver for you. Once you're back into X run glxinfo |grep -i direct to see if direct rendering is enabled. If not, have a look at your /var/log/Xorg.0.log which should have some clues. -- James A.
