how to reset compiz and unity completely?
After the upgrade from 12.04 to 12.10 compiz and unity constantly crash. I tried reinstalling them and using unity-reset programme but it does not totally reset unity and compiz. Compiz and unity do not crash on any other accounts on the laptop so I guess there is something wrong in the config files. So I'd like to completely reset the settings by probably deleting all config files and let the programmes recreate them again but I am not sure where they now are located. Any help is really appreciated.
