Problem description
The compiz grid feature just stopped working a couple of days ago: for instance I used to be able to move a terminal window to the top left corner by pressing <ctrl><alt>KP7 but now the number 7 appears in the terminal and the window doesn't move.
Troubleshooting
-compiz grid is enabled and I have restored its configuration to the default values
-my numpad is working properly (i.e. if it's locked I get the numbers, if not I get home, ins, del... as expected).
-I looked into the Keyboard and Keyboard layout settings but I don't see any option I could tweak to fix the problem.
What do I need to do in order to restore the compiz grid feature?
