Bug ID: 468436
Summary: Often when away from laptop, desktop has
crashed/restarted when I come back, with kwin crash
note in dmsg
Classification: Plasma
Product: kwin
Version: git-stable-Plasma/5.27
Platform: Neon
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: larsi...@igesund.net
Target Milestone: ---
Relatively often when going away from the laptop (it is connected to power, so
don't go to sleep or similar, just screen goes to black), the desktop has
relatively often restarted when I get back.
Today is first time I have checked, but dmesg had this
kwin_wayland[43369]: segfault at 10 ip 00007fa9471d0c14 sp 00007ffcb18c4518
error 4 in libkwin.so.5.27.3[7fa946f58000+32d000]

I am sorry that I don't immediately know if it is possible to get a stack trace
from this, or if it is relevant.
A potentially relevant note (at least it was this today, I don't remember if it
was like this previous times, but I have a feeling they were):
I bring my laptop to the office about once a week (today was such a day). There
I connect it to a USB-C dock (Dell make), and attach keyboard, roller mouse and
an external 4K Dell monitor. When going home, I disconnect the dock, close the
lid and put it in my backpack. Home, I take it out and connect it. This evening
I left home for a while, and when I returned, the above had happened.
STEPS TO REPRODUCE
1. Go away from laptop, possibly after been through some laptop lid closing and
opening and such
OBSERVED RESULT
Desktop has restarted all by itself
EXPECTED RESULT
Desktop doesn't restart all by itself
