I had the same problem. If you have the book for your monitor it should
have all your supported timing and scanning , Vertical, Horizontal
refresh rates you will see what your monitor is capable of.
When you do dpkg-reconfigure xserver-xorg you should see what
resolutions you can do with it.
What worked for me was to use the medium setup and select the vesa mode
and I selected conservatively at 800x600 60hz. Then when I startx from
the terminal a strange colored screen first came up but then GDM started
and all was well. All the screen resolutions were available in X.
Hope this helps and is understandable.
p.s. follow the other posts about reconfiguring the server and killing
the graphical screen.
