Я выхожу из системы автоматически через несколько секунд после входа в систему (рабочий стол)
Я вышел из системы (не заблокирован) из сеанса рабочего стола после входа в Ubuntu 16.04 LTS
Я вижу следующее на /var/log/lightdm/seat0-greeter.log

/var/lightdm/lightdm.log
сразу после входа показывает следующее:

Похоже, вам не хватает видеопамяти. Я столкнулся с той же ошибкой на VirtualBox, когда настроено только 32 МБ видеопамяти. Когда я настроил VRAM, чтобы иметь больше памяти, проблема была решена (в моем случае я сделал это 128 МБ).
