Eu acabei de atualizar o Kubuntu para o 15.04. Quando eu chego na tela de login gráfico do SDDM, depois que minha senha é aceita, eu recebo a tela inicial do KDE com uma barra de progresso de carregamento, então ela fica preta em 75% (mostrando "Iniciando versão 219", eu entendo problema e pode ter a ver com meus drivers Nvidia) e me joga de volta na tela de login novamente. Eu posso logar se eu selecionar por exemplo LXDE ou Openbox como o meu DE, mas não o KDE ou o Gnome.
Eu tentei isto:
sudo apt-get install gdm (select sddm in the configuration dialog)
sudo dpkg-reconfigure gdm (and select sddm again)
sudo apt-get remove gdm
Eu tentei sudo systemctl enable sddm.service -f
Eu tentei rm .cache/upstart -rf
Eu tentei apt-get install upstart-sysv para substituir o systemd.
Aqui estão os meus ~ / .xsession-errors de um lançamento fracassado do KDE. Uma linha possivelmente significativa é esta:
