Я только что обновил Kubuntu до 15.04. Когда я добираюсь до графического экрана входа в систему SDDM, после того, как мой пароль принят, я получаю заставку KDE с индикатором загрузки, затем он отключается примерно на 75% (показывая "Начиная с версии 219", я понимаю, что это отдельный проблема и может быть связано с моими драйверами Nvidia) и снова выводит меня обратно на экран входа в систему. Я могу войти, если я выберу, например, LXDE или Openbox в качестве DE, но не KDE или Gnome.
Я попробовал это:
sudo apt-get install gdm (select sddm in the configuration dialog)
sudo dpkg-reconfigure gdm (and select sddm again)
sudo apt-get remove gdm
Я попытался sudo systemctl enable sddm.service -f
Я пробовал rm .cache/upstart -rf
Я попытался apt-get install upstart-sysv чтобы заменить systemd.
Вот мои ~/.xsession-ошибки от неудачного запуска KDE. Возможно, важная строка такова:
