and Gene responded with a copy of his xorg.conf file from Ubuntu 6.06.

Gene highlighted the essential part of this file thusly

The critical line here is 'Driver "vesa"'. The identifier is a string
used so the Xserver can distinguish among possibly multiple devices; so
long as its value is unique among the identifiers used in your conf file
it can be your choosing. You can hand-edit these two lines. I had no 
need to identify the card's BusID explicitly, but as usual, Your Mileage 
May Vary.

On the upside to the evolution of the Xserver, the Xorg crowd has been
working to simplify configuration. See
https://help.ubuntu.com/community/XORGHardy for one description of the
process for Ubuntu 8.04LTS. Don't put anything into xorg.conf unless you
have to. Enter "man xorg.conf" on your Ubuntu box to learn more than you
ever wanted to know about the options.

If you happen to bork your Xserver (bork is a technical term that
describes many of the mistakes I've made when I acted without thinking
and some when I was thinking), you can reboot and choose a recovery mode
when the boot menu shows up. From the recovery menu, choose "root
drop to root shell prompt" and at the command prompt enter the command 
"dpkg-reconfigure -phigh xserver-org" to reset your configuration to 
something that has a reasonable probability of working. Then reboot 
normally (there is an alternative to rebooting at this point, but why 
overload your inbox with more commands?).

Regards,
Kent


PS - sorry for the delay in responding. The 100+ deg-F dry-bulb 
temperature here in the DC area seems to be affecting my ISP. My 
Internet connection comes and goes without warning.
