I need help resolving a screen resolution problem. I have Ubuntu 7.04 loaded
on a Dell Dimension L700cx system. It is a single boot. I am using a
Princeton VL1918 monitor. The only screen resolution available is 640 X 480.
The Dell uses the 810E chip set and according to the documentation, has the
following resolutions available: 640 X480, 800 X 600, 1024 X 768. 1152 X
864, 1280 X 1024 and 1600 X 1200.  The monitor synchronization is 31 to 81
Hz horizontal and 56 to 75 Hz vertical. The ergo. Resolution is 1280 X 1024.
I have attempted to use sudo dpkg-reconfigure xserver-xorg to no avail.

On startup when I type my name the characters are so small they are not
readable. I have only one resolution choice, 640 X480 and 73 Hz.  When I try
to enter a new contact in the Thunderbird contact window the window is so
large I cannot get down to the OK button.
