Ошибка libgl, Unity и compiz не загружаются при запуске

Недавно, когда я перезапустил свою двойную загрузку Ubuntu (Windows 7 и Ubuntu 12.10), все, что я вижу, это просто мой рабочий стол, без черточки, без панели запуска или каких-либо панелей управления. Вот вывод команды usr / lib / nux / unity_support_test -p:

 libGL error: failed to load driver: swrast
 libGL error: Try again with LIBGL_DEBUG=verbose for more details.

Также, когда я пытаюсь запустить compiz вручную с помощью терминала, я получаю следующий вывод:
