Which says the autologin did complete, but the session exited for some reason. You may be able to find out why by looking at ~/.xsession- errors. Otherwise the issue is probably in mate-session. -- 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/1511841 Title: autologin fails for administrator user Status in lightdm package in Ubuntu: New Bug description: I had two user accounts on the machine, an administrator and a normal user. I edited a conf file in /etc/lightdm to auto login the unprivileged user, which worked fine. I then deleted the unprivlieged user and changed the config file to autologin the remaining user. This does not work, a password prompt is always presented to this user.
