unresponsive desktop

Nice to know: if your X desktop becomes unresponsive, it's probably because some app has locked up while it has 'grabbed' the mouse and keyboard inputs, and killing the guilty process will release it. So drop to a console and start picking off suspicious processes until you regain control.

EDIT: and if that only frees up the keyboard, leaving the mouse stuck... relaunch the guilty app that you killed, and close it again. You get the mouse back!

EDIT: Here's another (new?) way of dealing with it. Keep in mind some apps may crash if you take away their toys :)
Section "ServerFlags"
  Option "AllowDeactivateGrabs" "true"
If this works, X will allow the Ctrl-Alt-(keypad "/") combination to ungrab the mouse and keyboard.
