Here is additional info. From terminal as root I stopped kdm.service and started sddm, which failed to start, reports follow. This is output of 'systemctl status sddm.service'. ● sddm.service - Simple Desktop Display Manager Loaded: loaded (/lib/systemd/system/sddm.service; enabled; vendor preset: enabled) Active: failed (Result: start-limit) since Sat 2015-09-12 21:52:34 EDT; 12min ago Docs: man:sddm(1) man:sddm.conf(5) Process: 1639 ExecStartPre=/bin/sh -c [ "$(cat /etc/X11/default-display-manager 2>/dev/null)" = "/usr/bin/sddm" ] (code=exited, status=1/FAILURE) Output of 'journal -xe' is much larger, Debian paste would not take it so had to use pastebin. pastebin.com/DQ9WBp4Y After setting sddm as default-display-manager in /etc/X11, and rebooting, I got a completely black screen. Had to tty again and set kdm back as default to get normal boot again. I think that severity is grave since sddm is unusable. On 09/16/2015 07:11 AM, Maximiliano

I couldn't reproduce the bug as reported. But since the log showed starting sddm from tty1 after an upgrade I tested sddm with a running display-manager, it fails in similar ways to the reported error. Either having an X on tty7, an non-stopped kdm, lightdm, or any other display manager running in tty7 would fail. I think that sddm is failing to detect the 'seat' already in use. I'll keep on investigating this issue. In the mean time, it would be nice to if you could check if stopping a running display manager before starting sddm allows sddm to work for you, as this would confirm that we are talking about the same issue.
