Comment 6 for bug 87185

well i had similar errors on console when manually issuing a compiz or compiz.real --replace as Johan says he has. I actually got compiz up using the desktop-effects control panel but i got partial effects (windows wobbled) but the cpu usage was very high, and there were lots of visual artifacts (banding, almost like what an refresh rate overdrive used to look like) but these lasted for fractions of a second intermittently showing what ought be painted from the buffer. After reading your e-mail i tried again to issue compiz via the terminal but it basically made my desktop unresponsive (could'nt change window focus, missing decorators, high cpu utilization, other random weirdness. and i couldnt coax any terminal error output :-(

running nvidia v9631 w/ whatever is built into the xserver (AIGLX i think)

btw to anyone else trying to get some terminal output issuing compiz, ctrl-c and type "metacity" to bring back your desktop w/o having to kill the whole xserver.
