Thanks. Unfortunately it seems that crash file is not one of the
convenient ones with a readable stack trace built in so we need to
submit it for processing. Please run this command on the original
machine:
ubuntu-bug /path/to/_usr_bin_gnome-shell.1000.crash
I am making this bug private while
It just happened, so attached the crash file that was generated. NB:
gnome-shell 3.26.1-0ubuntu2
mutter 3.26.1-1
libmutter-1-0 3.26.1-1
NB: I notice there's also a libmutter-0-0 installed, possibly a hangover
from the original zesty install. but ldd $(which gnome-shell) indicates
it's linked to
I’m afk today but will try to get this information on Wednesday.

Title:
gnome-shell segv on wake from display or system
Rachel,
We are tracking hundreds of gnome-shell crashes right now and have had a
few recent ones related to monitor configurations too.
In order to make progress on this bug we either need a stack trace (look
in /var/crash for crash files), or someone who experiences the problem
to debug it
Looks like this...

That wouldn't surprise me. I've seen other reports, on IRC, to the same
effect. Sadly, displayport is not optional here, not if I actually want
to run my monitors at full resolution.
Someone mentioned it being a "known bug" in mutter? However they didn't
link to it and I wasn't at the keyboard at
This issue is occurring for me too with amdgpu. I experience the same
problem under both Xorg and Wayland sessions. This is only an issue with
my monitor connected via DisplayPort - when I connect via HDMI gnome-
shell does not crash if the monitor goes to sleep.

ok, same symptoms occurred with the default theme. So after all it looks
like the shell theme has nothing to do with it.

well I spoke too soon. Crash occurred with the locally 'built' arc
theme. Slightly different though in that this time it *did* hang the
system. But it started with the same segv message logged. So back to the
default+Ambiance theme to test that for longer.
Problem with trying to prove a negative.
Of interest, I can reproduce this on Ubuntu 17.10 beta, however it
doesn't occur on Debian Stretch. However I didn't test theme settings,
and was running Pop_OS! themes at the time. Next I will see if it
occurs with stock themes.

arc-theme package uninstalled and instead arc gtk & shell themes
installed manually as directed in its github page via autogen. This
appears not to be triggering the crash. even though the autogen doesn't

was ever applied. It *did* get applied just now with a routine dist-
upgrade, which included an update to console-setup, which forced update-
initramfs. And then the system was unbootable except via the recovery
system.
It may be the Arc shell theme, in interaction with nVidia:
I was unable to reproduce the problem on the Macbook Pro using Xorg
gnome session, and that still with the Arc shell theme. Both a short
(few minutes) and long (greater than one hour) display sleeps tested.
I was also unable to reproduce
That would appear to be very different from what we're trying to report
here:
1. It's not hanging. It's presumably exiting, forcing a logout, and it
all happens before the monitors are awake enough to show a picture.
We're not in a hung state at any point.
2. It's not only suspend, it's wake
I've had GNOME Shell hang on wake from suspend some times. I have Intel
graphics, not NVIDIA. I am using the default Ubuntu session (Wayland).

neither change made a difference in the end. the needs-root-rights
change (instead of, not as well as, modeset) didn't help either, after a
long sleep.
Why instead-of not as-well-as? Because the manpage for Xwrapper.config
said that its default setting of 'auto' turns needs-root-rights off is
kms
Just to +1 - those changes did not impact 'long term sleep' crashing the
shell.

... and the answer is no. After a longer display-sleep i woke it up to
find myself back at the login prompt. Definitely that and not the lock
screen.
This may in part be related to long-term issues I have with this

I tried the modeset change first, as that one we'd presumably prefer to
be true anyway one day, whereas giving stuff root that isn't supposed to
have root never feels right. :-)
It worked. I left it to display sleep for a couple of minutes and on
wake I came right back to the desktop. (I don't
I also edited /etc/modprobe.d/nvidia-graphics-drivers.conf and set
'modeset=1' for the nvidia driver where it was previously 0, you might
give that a shot and if that works we can mark this a duplicate.

I can't reproduce this in Xorg on my non-nvidia machine (on which I
normally run Wayland because I can). It appears to be nvidia specific.

I have the same issue - screen blank is enabled, suspend is disabled.
Using proprietary NVidia driver also.
