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.
