Another option would be to ssh to the machine from another machine. Then 
you could even try to find out what is still working or what process 
might be hanging. Granted, you need a second machine and you need the 
ssh server running, which is not a default setup.

Screwed up? Again? It is a very old change, introduced in 9.04 because 
people complained after they accidentally hit the shortcut. And you can 
easily revert the change if you so desire:
