[Problem]
System with i815 graphics fails to properly detect the monitor and thus provides only 800x600 resolution.
This worked on the -intel driver back with xserver 1.3 and -intel 2.1.1 (Gutsy) providing 1280x1024, but regressed in Hardy and has been tested through Ubuntu Karmic Alpha-2.
[Original Report]
With upgrade to hardy the highest possible resolution reduced to 800x600.
In gutsy and dapper the highest resolution was 1280x1024@60 Hz on the same hardware.
The system was upgraded from dapper to hardy.
