Window Toolbar went MIA
 

Hi everyone. Im a new Ubuntu user. I was messing around in CCSM a while ago and i must have done something because when i maximize my windows i lose the toolbar with the close, minimize, maximize buttons.

N00b question i know but i cant figure out what i did. anyone who can help?

If Alt-F2 fails to bring up a run dialog, then your window manager has crashed. To fix this, bring up a nautilus window (use the menu button in the panel), navigate to /usr/bin, then double-cleck either metacity or compiz to execute.

If Alt-F2 brings up a run dialog, then a simple press of F11 should cure your problem
