I copied your report and edited in my on-upstart observations: I got the prompt asking me whether I wish to run lightdm or sddm and I chose lightdm. However after reboot I got a text login on TTY1. (NOTE: Very fast, a fraction of time needed for reaching a login manager on that machine)
Running "service lightdm status && service sddm status" told me that they both were STOPPED. I could run "service lightdm start" or "service sddm start" to start either one manually, but not automatically. So it's not just on systemd. NOTE: Even though I selected "lightdm" during sddm installation, /etc/X11/default-display-manager was still overwritten to says "/usr/bin/sddm" I fixed that by working around #1422247 and deinstalling sddm. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446760 Title: sddm and lightdm can run at the same time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sddm/+bug/1446760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
