[Bug 1446760] Re: sddm and lightdm can run at the same time

Sat Apr 9 12:38:12 UTC 2016

** Description changed:

  I originally installed Ubuntu MATE 14.10 which I then updated to 15.04.
  At some point I decided to try KDE Plasma 5, so I installed the kubuntu-
  desktop package.

  I got the prompt asking me whether I wish to run lightdm or sddm and I
  chose lightdm. However after reboot I got black screen which loaded
  plasma cursors and I was unable to do anything without going to TTY.

  Running "systemctl status lightdm && systemctl status sddm" told me that
  they both were running and I solved this with "systemctl disable sddm"
  and rebooted and got lightdm normally.

  I think this might have something to do with Ubuntu 15.04 using systemd
  by default and sddm not having systemd unit.

  PS. I am not fully sure if this is sddm issue, but I feel this is. Feel free to move this to correct place if I am wrong.
  PPS. I experienced this week or two ago, but I don't think there have been upgrades to these packages, so I am sorry if this is known issue and already fixed.
