Sometimes sddm-greeter will refuse to start. The greeter simply presents a blank screen. A syslog entry shows:
Jan 5 16:24:43 jason-verix kernel: [ 1666.636093] sddm-greeter[2074]: segfault at 18 ip 00007f49c6e30e38 sp 00007ffdeda61c70 error 4 in libqxcb.so[7f49c6de7000+b5000]
This happened every time. I tried restarting via systemd:
systemctl restart sddm
This produced the same error. I tried restarting X with no luck, also pkill'ing X - still no luck. So, I brought down SDDM:
sudo service sddm stop
and brought it back up
sudo service sddm start
And it came up. I don't understand why. Frustrating!
Note that it may be worthwhile delaying the start of sddm to give the video driver more time to initialize the displays. Another set of problems I was having was resolved by this technique, which is described here:
