I have tried the following without success: - chown maroual:maroual .Xauthority (as it was owned by root) - rm .Xauthority and then reboot - I have verified that the umask and owner of /tmp and /home/maroual were correct - sudo dpkg-reconfigure lightdm - sudo apt-get install --reinstall ubuntu-desktop - apt-get update then upgrade then autoremove then check - inspected the following files and logs: .xsession-errors /var/log/Xorg.0.log /var/log/Xorg.0.log.old /var/log/lightdm/seat0-greeter.log /var/log/lightdm/x-0.log /var/log/lightdm/lightdm.log journalctl -u lightdm systemctl status lightdm.service dmesg
sudo service lightdm restart just allows me restoring the login screen after a failed attempt Thanks for your help -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1753233 Title: Task bar and launchpad are missing Status in lightdm package in Ubuntu: New Bug description: I am using Ubuntu 16.04.4 LTS and lightdm 1.18.3-0ubuntu1.1 After I enter my password in the login screen, both task bar and launchpad are missing.
