I've succeeded in reconfiguring xorg, and now I can change the resolution by System >> Preferences >> Screen resolution.
first, and MOST IMPORTENT, backup your /etc/X11/xorg.conf file.
the following command might wreck your graphical system..Do it only if you safe about going to other tty's and trying to recover X
sudo dpkg-reconfigure -phigh xserver-xorg
and then restart X by log-out. (no, ctrl+alt+backspace doesn't seem to do enough)
Good luck
