As root do: $ chown -R joe /home/joe and login as joe Create another user and try login with it. Does it work? If it doesn't work: Make sure that ``/tmp`` folder has full write permissions of everyone. If not, fix it Disable graphical login i.e. (``systemctl set-default multi-user.target``) and reboot. Try to start x with ``startx`` from the console. Does it work? If not, check /var/log/Xorg.* log
