Public bug reported: Just upgraded from 12.04 to 12.10 beta. I have a dual monitor setup and the monitor connected to the VGA port is useing a reduced default resolution (1024x768) instead of it's native resolution 1280x1024 since the upgrade. I also noticed that the EDID information is missing from Xorg.0.log.
I also attach an old Xorg log file (from 12.04) where the EDID information is correct.
