Hi John,

Annoying, I know, I had the same problem.
Have you checked your Xorg log file (in /var/log)?
It probably discards most of the resolutions.
If the driver you are using is Radeon, then it might help to switch on 
the DDCMode (it's in one of the other mails).

I quote from that mail:

"
Sounds like you have the same problem I have. The xorg drivers stick me 
with a 640x480 on my Radeon X700, regardless of monitor settings. Try 
the option: Option "DDCMode" "On" In the device section in 
/etc/X11/xorg.conf, and it will probably fix it.
"

If you are not using Radeon, check the manpage for your driver.

Hope this helps.

Guus.
