Comment 11 for bug 430981

Same here, following the steps (turn off compiz, set keybindings, reboot, re-enable compiz) has fixed the issue, my keybindings stay set after subsequent reboots, keeping compiz on. I just upgraded my desktop to alpha 6.x yesterday, so I'll check if it is affected as well. The machine I encountered the issue on had been upgraded to alpha 5, so it might be a setting that was messed up from an earlier package.
