Bug Description
The automatic configuration for a Sony Multiscan E200 (model #CPD-E200) does not support any resolution modes higher than 1024x768. The monitor is built to support resolutions up to 1600x1200, per the Sony specifications for the monitor seen here:

An expanded range of resolutions can be enabled by updating HorizSync and VertRefresh parameters in /etc/X11/xorg.conf as follows:
Section "Monitor"
Identifier "CPD-E200"
Option "DPMS"
HorizSync 30-85 #add this line
VertRefresh 48-120 # add this line
EndSection
Relatively minor, but one of the many small details that would improve user experience if the appropriate configuration happened automatically instead of with a manual override. I am submitting this bug report on the advice of Bryce Harrington, who said this would be the best way to make sure future versions of Ubuntu incorporate the fix.

Please attach your /var/log/ Xorg.0. log. The driver should get the right mode. Also, try Hardy alpha2 if it's better.
