Run Compiz on Blacklisted Hardware
Are you using unstable video driver ?, Do you have older hardware which is not properly supported ?. If this is the case then the chances are that your hardware is blacklisted by compiz. But compiz provides a nifty way to skip these checks.
Execute following command to start compiz without black list checks.
Another way is adding following option to ~/.config/compiz/compiz-manager file.
