Can you quickly check in the logs at the time of the crash if gnome- shell/mutter had crashed or failed to start (I've seen this happening as well at startup, gnome-shell starts, spawns Xwayland, then fails, and Xwayland aborts in xwl_read_events()) Reply at: https://bugs.launchpad.net/ubuntu/+source/xorg- server/+bug/1731911/comments/12 ------------------------------------------------------------------------ On 2017-11-18T06:51:36+00:00 Justin wrote: I am also experiencing this on Fedora 27, 4.14.0-1, Nouveau, t I think you're right Olivier, this is likely from a crash in mutter: I see in the logs: gnome-shell: segfault at ... in libmutter-1.so.0.0.0... gnome-logs: Error reading events from display: Connection reset by peer kernel: (EE) Xwayland: ANOM_ABEND ... gnome-session-b: gnome-session-binary: WARNING: Application 'org.gnome.Shell.desktop' killed by signal 11 (stack trace...) systemd:coredum: Process 2515 (gnome-shell) of user 1000 dumped core.

It seems to happen when I have the screen off (perhaps a notification triggers this crash? or turning the screen on, which activates the Displayport link, triggers the crash?) I have mutter and gnome-shell at 3.26.2-1, and gnome-session(-xsession, -wayland-session) at 3.26.1-1. Please let me know what more would be useful.

The problem is easily and always reproducible. The steps are : 1. login properly 2. power off monitor (or wait until screen saver cause the monitor to auto-sleep) 3. power back on the monitor (or wake-up from monitor sleep mode) It reports "gnome-shell" was crashed and I have to re-login again. I used just an ordinary HDMI full-HD monitor. This always happens, even just after fresh reboot. Should be something when the HDMI connection back on caused something to crash.

Basically, gnome-shell (now) runs Xwayland with “-core” which means that *any* FatalError() in Xwayland will dump a core file. xwl_read_events() triggers a FatalError() because the Wayland socket is unusable, and it's unusable because the Wayland compositor (the other side of the socket) has died, i.e. crashed most likely. The Wayland compositor is gnome-shell/mutter, so if you could please look into journalctl and coredumpctl to find a backtrace and/or generate one with coredumpctl and gdb. >From comment 15, this is most likely a dupe of bug 1500325.
