Resolution changed and can't be returned to original resolution.

[Tony K.]

Help!!! Mystery depends...

I decided to reboot my desktop because it was running a little
sluggish.  Probably just caching in Firefox or that I have been
working a lot with GIMP and images today.  Anyway, I happened to check
the uptime and I had not rebooted it in 11 days.  Hence not rebooted
since before my resolution problem appeared on my other Ubuntu server
machine.

I rebooted and now have the identical problem with loss of resolution.
 I normally run on 1024x768.  I now have two machines stuck on 640x480
60Hz.  Following is my xorg.conf settings.
