Comment by Stach Jemiola (jemiola) - Thursday, 24 September 2015, 19:28 GMT
"systemctl restart sddm" allows to start sddm.
Comment by Bruno Pagani (ArchangeGabriel) - Monday, 28 September 2015, 14:39 GMT
Got this too: sddm-helper[1282]: segfault at 14 ip 000000000042965e sp 00007ffc87758020 error 4 in sddm-helper[400000+3a000]

However, I though it started when upgrading to systemd 226, but it might not be linked.

Sometime restarting X (configured Ctrl+Alt+Suppr for that) also works to bring sddm back.
Comment by Rene Pasing (DeLord) - Wednesday, 30 September 2015, 23:50 GMT
Hi, I am also experiencing this bug, is this upstream? If yes, any news to that? Couldn't find anything. If not, how to fix?
Comment by Hans Schwimmbeck (hans) - Thursday, 01 October 2015, 06:29 GMT
With sddm-git commit c637727 from the AUR I don't experience the segfault any more.

There are only a few commits since the 0.12 release. Most of them are obviously unrelated, so it should not be too hard to make a patch.

Comment by Antonio Rojas (arojas) - Thursday, 01 October 2015, 06:53 GMT
Please test 0.12.0-3
Comment by Admoni Rotem (rotema8) - Thursday, 01 October 2015, 18:42 GMT
With caution after several reboots during the day : fixed for me.
