I've upgraded from Jaunty to Karmic and since then my machine is locking every time i try to enable compiz effects through System > Preferences > Appearance, tab Visual Effects. Selecting any option but "No Effects" will cause the system to totally lock up: screen locked, mouse not moving, keyboard not responding (caps lock or num lock leds not responding when pressing the keys), hit the power button cause no effect, I have to turn the machine off by holding the power button and turn it on again.
I'm using ubuntu in this machine since the 8.04 version (compiz almost fully enabled), everything was working fine until I upgraded to Karmic.
Binary package hint: compiz
