Comment 63 for bug 539477

And another heads up,

I have a Dell Studio 1558 and use Gnome with Gnome-Do. I couple of days ago I connected an external monitor for the first time and maybe also tried Fn+F1 to activate the VGA port. After doing that (and rebooting various times) Super+P does not launch Gnome-Do anymore as I configured it before but only removes my mouse arrow for parts of a second. If start Gnome-Do through the menu, change the key to start Gnome-Do to e.g. to Super+J, close Gnome-Do, reopen and configure it back to Super+P it works again. When I then use Fn+F1 it also opens Gnome-Do.
Unfortunately this all only lasts until the next reboot and then I can start reconfiguring Gnome-Do once again.
