Idem here, 18.10, every app crashes - including the gnome session -
after the screen goes blank into powersaving.

I have the same crash in 18.10: if the screen automatically blanks after
1 minute, gnome crashes and the login screen appears.

I am having this issue despite having auto off feature disabled. The issue
doesnt start until my monitor is turned back on; I put my /var/log/syslog
entries here:
https://pastebin.com/QTe2QvHX
with this being where the segfault happens:
Oct 31 10:34:40 server kernel: [46047.363402]
Turning of the screens auto off feature seems to have fixed this for me.

Title:
Screen blanking and/or screen lock crashes
Just retested a few times. EVERY time I turn of my monitor, the session
dies. Therefore I think my issue might be related to that my monitor has
an auto off function.
In dmesg I get the following every time it dies:
[108839.489217] gnome-shell[26345]: segfault at 38 ip 7f58e823ac30 sp
Oh, I should mention that by "auto off function", I mean that it turns
completely off so I need to push the power button again. I am trying to
disable this now, and see how it goes leaving Ubuntu setting for turning
it off enabled.

Just experienced this after disabling the screen powerdown in power
settings, and then I just turned of my screen. However it didn't seem
like my session died before I turned the screen on again. At least thats
what I think since my 7z compressions I started before turning off the
monitor did
Bummer. It just did it again after automatically shutting the screen
off.

Screen blanking and/or screen lock crashes
I had the same issue in an Intel integrated graphics card (Core
i3-2120T). My whole session would just die.
My system is in Danish, so I am unsure if it is the power saving option
mentioned by @emanuel-pirsch I have disabled, but I went to the power
settings and disabled the second option that
It may be related to the "Multi Monitors Add-On" extension. I've
disabled it and now it works fine. Will update if I have any more
crashes.

I have the same issue, running on a laptop with a dual monitor splitter
plugged in my displayPort.
The crash happens under Wayland and XOrg.
I've disabled auto-source selection on the monitors.
The crash happens only when I log-in after the session has been locked.
It also happens when I press
Disabling Power Saving on the monitors seems to help.

I did some experimenting. The wayland gnome-shell crash and monitor
power-saving issue seems to be limited to a hdmi connection, and has
something to do with the monitor searching for a signal on other inputs
after it has been blanked.
I dug out an old d-sub vga cable and connected the monitor to
Filed against Xorg due to selection limitations of apport. Mutter is the
best guess of responsible application/package.
