How to Reset Ubuntu/Gnome Settings to Defaults without Re-installing

Keep in mind that this will only reset your Gnome-specific settings. If you are having problems with your video card, display, x-server, etc., this WILL NOT fix your problems.

If you don’t have access to your graphical (GUI) desktop to delete these folders in Nautilus or you’re stuck at the login screen, drop to a terminal by hitting CTRL + ALT + F1, login to your account, and run this command:

rm -rf .gnome .gnome2 .gconf .gconfd .metacity

Get back to your GUI desktop by hitting CTRL + ALT + F7.
