Невозможно войти в Ubuntu после обновления до 12.04.

Сегодня я не могу войти в GUI, но я могу использовать консоль ( Ctrl + Alt + F1 ), чтобы войти как пользователь или root, и я могу войти через ssh.

Под Natty до обновления я настроил Ubuntu для автоматического входа в систему как пользователь. В пятницу автологин работал с 12.04. Сегодня мне впервые представлен экран входа в систему. У меня нет запроса на ввод идентификатора пользователя, просто пароль.

Я попытался удалить и переустановить lightdm, но это не помогло.

У меня есть 3 виртуализированные системы Ubuntu; у двух из них есть эта проблема. Что мне делать?

Что я сделал, чтобы решить эту проблему, так это удалить и переустановить lightdm и ubuntu-desktop. Исправлена ​​проблема сразу. Возможно, вам придется убедиться, что вы удалили кэшированный пакет и убедитесь, что он загружает свежую версию из хранилища.
