Similar 'problem' in Debian. However, it is not really a problem.
Apparently xorg does a better job of detecting your monitor than
dpkg-reconf of xserver-xorg package. What ended up working for me was to
let xorg make a new xorg.conf file by itself and it detected all the
resolutions of my new monitor. To do this:
1. Go to a tty (CTRL+ALT+F1 for example) and use sudo for the following
steps.
2. Rename your old xorg.conf file (in /etc/X11/) to something else (to
keep a backup). Then xorg.conf should not exist.
3. Restart gdm (sudo /etc/init.d/gdm restart). You should get a new
xorg.conf file and good resolutions now.
4. If the above doesn't work, you have the backup of the earlier
xorg.conf file. Use that and post there.

Regards.
