    I did the tests and the results were interesting. On this computer 
with nVidia it allows me to set it for Extra and it will reboot into the 
Extra mode. But what happens is an old problem that is not one now comes 
back. As soon as I turn on firefox to a busy page the screen changes to 
a odd pattern of 45 degree lines. This also kills the mouse and the 
keyboard. The only way back to normal use is to turn off power, and then 
reboot and quickly change back to no effects.

    My laptop has an ATI VGA device and it will not even let me set up 
for Extra. It fools around and then says it cannot set this mode.

    So you must do something else to get compiz working. What is it I 
wonder?
