after I log-in into Unity, compiz effects are disabled and it says compiz crashes. Restart of them usually works, but not every time. After restart of compiz, compiz works without problems, every effect is OK. I tried latest NVIDIA drivers from xorg-edgers, but situation is the same. I tried to delete folder with compiz settings, but it hasn't helped. I use two LCDs, but with only one enabled, the situation is the same. Thank you for suggestions.
