this is really useful information!
Thanks, saved me rebooting and works for ubuntu 12.04b2
I am occasionally loosing the window edges in 12.04 and this is a nice trick to get them back. It gathers all the apps back to one workspace, but... still a lot easier that logging out.
Very very useful, thank you!
This is good but if you're running gnome and your video card does not support compiz, your window manager will be broken.In that case just run "metacity" again to restart it, you will need to do it from a tty prompt or SSH.
Great trick, very thank you !
Wow! That is a very nice fix! Thank you!
