Can you try 3.26.0? This looks like bug 730551 which landed in 3.25.92, but this bug report mentiones 3.25.91.

At least one Ubuntu 17.10 tester reports the same crash: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1717170/comments/8
(In reply to Daniel van Vugt from comment #4) > At least one Ubuntu 17.10 tester reports the same crash: > https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1717170/comments/8 As Daniel wrote, I have the same issue. Tested on Ubuntu 17.10 (with the latest updates) with gnome-shell 3.26.0-0ubuntu1 & mutter 3.26.0-1
Another Ubuntu 17.10 user here with this issue. Using the same version of gnome-shell and mutter as Ryzko. Problem occurring when turning off the TV my NUC is connected to (GPU is Intel Iris 580).
Created attachment 360374 [details] [review] surface-actor/x11: Don't try to unredirect when headless We don't have a monitor size to compare a window size with, so don't attempt to determine whether to unredirect when headless.
Created attachment 360375 [details] [review] window: Don't try to auto-maximize when headless Automatic maximization is done when a window is almost the size of the work area of a monitor. This makes no sense to try when there is no monitor available, so skip trying to do this when headless.
Quick note to mention that I managed to reproduce exactly the same issue (same backtrace) just by booting without a monitor after having all the patches from bug 730551 (including https://bugzilla.gnome.org/attachment.cgi?id=360379&action=diff) applied. See https://bugzilla.gnome.org/show_bug.cgi?id=730551#c82 At the same time, I can confirm that applying the patches from this bug locally made the crash go away.
I have noticed another strange behaviour bound to this bug, if the "Dim screen when inactive" option is enabled the connected monitor is going to power save state for a while after session "Lock" therefore session lost the primary monitor and the session crashed. With the "Dim screen when inactive" disabled the session is locking normally.
Review of attachment 360375 [details] [review]: right
Review of attachment 360374 [details] [review]: this would make more sense in meta_window_is_monitor_sized()
(In reply to Rui Matos from comment #12) > Review of attachment 360374 [details] [review] [review]: > > this would make more sense in meta_window_is_monitor_sized() I used the same reasoning here as with meta_window_is_on_primary_monitor() in bug 730551 that, if one checks whether a window is in a certain way with relation to some monitor when being headless, we should probably avoid checking that to begin with and handle being headless in a more explicit way.

TBH, I agree with Florian there. Even more so in this case since this is accessing a MetaWindow variable from a different class when we can nicely hide that behind the API call.

Fair enough, I replaced that commit to treat headless windows as being not monitor sized. Attachment 360375 [details] pushed as 6dd819a - window: Don't try to auto-maximize when headless
Created attachment 361027 [details] part of Syslog Today the update of mutter to version 3.26.1-1 was installed on my PC by "apt upgrade" and the issue still persist. Please see attached syslog, cut from the time of crash (caused by monitor switch off).

Please see attached syslog, cut > from the time of crash (caused by monitor switch off). Do you have gnome-shell 3.26.1 too?
no, still 3.26.0-0ubuntu2. Newer was not proposed by apt yet.
Created attachment 361043 [details] part of Syslog Hello, gnome-shell just updated to version 3.26.1-0ubuntu1 and the crash issue still persist, please see attached syslog. mutter was upgraded earlier to version 3.26.1-1.

Fixing of that backtrace was done in bug 788860.
I have the same issue, but the backtrace is different. For me, Gnome 3.26.1 on wayland on Arch Linux. I had 3 monitors plugged in and I unplugged an external one connected via USB-C --> displayport. Both gnome-shell processes crashed.

(In reply to Daniel Playfair Cal from comment #22) > I have the same issue, but the backtrace is different. That's a good enough reason to file a separate bug :)
Ok, here's a seperate bug report: https://bugzilla.gnome.org/show_bug.cgi?id=789501
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new ticket at https://gitlab.gnome.org/GNOME/mutter/-/issues/ Thank you for your understanding and your help.
