Running dpkg-reconfigure xserver-xorg as root (apparently) solved the problem. What I had to do was replace the autoselected ATI video driver with the VESA driver. I also chose "yes" to frame buffering. Changing the resolution did not seen to solve the problem. Note: In the GNOME desktop, when choosing the Screen Resolution menu option, the resolutions available are 1024x768 800x600 640x480 I have chose 1024x768 as the default resolution. Fine. But the only menu option available for any resolution is 85 Hz which works, but I don't like driving the video hardware that hard. I prefer running at 72 Hz or even 60 Hz. I would like to know how to reset the refresh rate. Anyway, thanks to all who responded to my query. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
