Невозможно запустить интерфейс Unity-2D в Ubuntu 11.10 [закрыто]

Я не могу использовать Unity-2D на моем компьютере под управлением Ubuntu 11.10.

Unity 3D работает без проблем.

когда я набираю единицу-2d-панель в терминале, я получаю следующее в терминале, и ошибка выскакивает и останавливается там.

Вывод терминала:
