So being sent into low graphics mode would be one problem and the screen overshooting (low tolerance for defective EDID) would be another, the prior being solved and the later to be seen in 13.04.

Symptoms: Constant flickering on and off of screen content, including distortion similar to a bad tv reception. The screen is a LCD Citizen C19604HD that should run 1440x 900 at 60 Hz (as per manual), which apparently does not have proper EDID. I should note this setup had no problems prior, until tty1 started to complain about a bad EDID checksum during 12.10 beta. Fix: Attempting to set my own xorg.conf evoked a message about running in low graphics mode. It asked if I wanted to (re)configure. I confirmed, after which I no longer needed xorg,conf, nor presumably Option "IgnoreEDID" "on" in xorg.conf which made xorg sessions usable. What should happen The system should be self-healing. The user should not have to grapple with xorg.conf (for hours or days on end with unfamiliar concepts [EDID] and work-arounds), and even less after all that time and effort just to have the system say, "Hey, I don't like what you're doing. Here, let me do it.". This (self-repair) hook should be invoked sooner in the trouble shooting process.
