-- Information about the crash:
System is a Dell XPS 17 connected to a Dell WD19TBS dock with two monitors
attached (HDMI and DP)
One external screen is set to be primary
I had done the following while reproducing a crash for bug 499383:
- Disabled the second monitor in Display Configuration (DP, not the primary)
- Locked the session (CTRL+L),
- Turned off the external screen (without unpluging the HDMI cable)
- Unlocked the session (from the laptop screen)
- Re-enabled the second monitor in Display Configuration
That had produced the same crash as in that bug
Then:
- Lock the session
- Go away for a while, the displays went to standby mode
- Unlock the session
- Dr Konqui reported a Segmentation fault in plasmashell
I see other bugs with similar backtraces, but they are all resolved (upstream)
e.g. bug 396359 and 449981 from 2023
The reporter is unsure if this crash is reproducible.
