While experimenting with sending virtual keystrokes, things got seriously hung up!
I powered off, When the system restarted all window decoration was missing, and all fancy compiz graphics was missing...
metacity --replace ... That brought back the window decoration.
...but still no compiz
compiz --replace ..... That brought back compiz functionality.
... but this time, no window decoration
How can I get Compiz and Metacity back together again?
...(so they can "live happily ever after")
