Вход в ubuntu 12.04 возвращается в систему [дубликат]

Это не проблема с разрешением, я использую нетбук, который годами работал нормально, у меня нет графики nvidia, гостевой пользователь отлично работает с существующей графикой, а добавление нового пользователя отлично работает с существующей графикой.

Я пробовал все, кроме одного из ответов в разрешении (создать нового пользователя и скопировать все заново, временное решение).

На моем ноутбуке dell установлена ​​версия 12.04.Давно работает отлично, до 12.04 с середины 2010 года работала предыдущая LTS ubuntu. Все работало нормально.

Вчера не удалось войти в систему с экрана приветствия, lightdm. Имя пользователя / пароль принимаются, но примерно через секунду возвращается к экрану входа в систему.

Я могу войти в гостевой сеанс нормально, и там все работает нормально, единство работает хорошо, проблем с графикой нет, все в порядке. И когда там с помощью ctrl / alt / F1, вы попадете в командную строку и войдете в CLI, также просто отлично, см. все мои файлы в домашнем каталоге encryptfs, так что пароль в порядке.

поскольку все в порядке с новой учетной записью и гостевым сеансом, я не думаю, что есть проблема с Xorg.conf.

Я удалил .Xauthority, без радости.

Моя домашняя папка имеет правильные права доступа drwxr-xr-x и принадлежит мне.

Обои принадлежат мне, но их могут читать все.

Мой жесткий диск, хотя и заполнен, все еще имеет более 5 ГБ свободного места df -h

Я пробовал sudo dpkg --configure -a; и sudo apt-get update; Не хочу обновляться с 12.04.

У меня нет nvidia, поэтому я не собираюсь пробовать их драйверы. Существующий драйвер отлично работает с новой учетной записью.

Я не хочу следовать процедуре сброса пароля, так как пароль не является проблемой, отлично работает на tty, и при попытке входа в систему с помощью графического интерфейса не приходит сообщение о недопустимом пароле.

Я подозреваю, что что-то не так с gdm, возможно, проблема с разрешениями при входе в систему как я. вот: 0-greeter.log

Спасибо, nerof61 Пробовал sudo chown -R chris: chris / home / chris

некоторые ошибки

chown: changing ownership of '/home/chris/.cache/compizconfig-1/staticswitcher.pb ': Input/output error  
chown: changing ownership of '/home/chris/compiz-1/session/10d1c......... ': Input/output error

При входе в систему все та же проблема, без изменений.

Если посмотреть на оба этих файла, они оба принадлежат chris: chris, длиной 0 байт, и оба последний раз изменялись два дня назад, когда машина в последний раз работала правильно. Я подумаю об этом, возможно, мне стоит переустановить compiz.

Я обдумывал проблемы с X. Проверил /hoe/chris/.xsession-errors, мне не очень помогло, надеюсь, кто-нибудь сможет указать мне правильный путь?

openConnection: connect:  No such file or directory 
cannot connect to br1tty at: 0
/home/chris/gnupg/gpg-agent-info-chris-laptop: Syntax error. '(' unexpected

Добавлю больше, когда найду Это.

Я пробовал добавить пользователя john с tty. После этого я перезагрузился и попытался войти в систему, точно такие же проблемы, даже с john, пароль принят, а затем практически сразу же вернулся к экрану входа в систему. Я все еще в порядке с гостевым сеансом и никаких проблем с ctrl / alt / F1

Позже. Я заметил, что домашний каталог нового пользователя john принадлежит пользователю root. используя sudo chown john: john john Я изменил владельца домашнего каталога. Теперь я могу войти в систему так же нормально, как Джон, так что я немного продвинулся.

Я действительно борюсь с этим, и любая помощь приветствуется.
