Comment 40 for bug 3731

An early preview about a GUI config tool we've been working on to help address this problem, since I know many people are having this problem and wondering what the plan is:

http://people.ubuntu.com/~bryce/BulletProofX/

This is not a true fix for the root cause of this bug, however it is going to be a better workaround than having to manually hand-edit your xorg.conf. The above link shows the tool in use when Ubuntu has completely failed to generate a working xorg.conf, and provides a failsafe environment where the user can select monitor/device settings.

The displayconfig-gtk tool will also be available from within Ubuntu's System menu, to allow re-configuration once Ubuntu has launched.

Neither of these capabilities are implemented in Gutsy yet, but should be within the coming weeks; I'll update here once there is something that can actually be tried out.
