Description Sebastien Bacher 2009-04-02 13:47:49 UTC 
The bug has been opened on https://bugs.launchpad.net/bugs/352754

"Essentially when trying to run duel screens from the laptop with an external LCD it is possible to cause the system to go into an infinite loop trying to find a pair of resolutions that will work.

There is a feature on the laptop (a key combination) which allows the user to switch moniors or have both displays mirror or have an extended desktop. It is this feature that there is difficulties with. The only way out of this is to force the machine to shutdown and restart.

I suggest that maybe there needs to be a one known good screen which the loop can terminate to. ie. Have the single laptop screen as the one known good screen. That way gnome can try finding the correct resolution for say 30 sec or so then timeout to the main screen. That way the user can feel back in control. A dialog box could pop up saying unable to find next screen, and ask to continue searching or to terminate. That way the user feels in control of the desktop.

Thanks for taking the time to report this bug.
However, you are using a version that is too old and not supported anymore. GNOME developers are no longer working on that version, so unfortunately there will not be any bug fixes for the version that you use.

By upgrading to a newer version of GNOME you could receive bug fixes and new functionality. You may need to upgrade your Linux distribution to obtain a newer version of GNOME.
Please feel free to reopen this bug if the problem still occurs with a newer version of GNOME.
