Description James Beddek 2022-02-15 10:40:17 UTC
Application: plasmashell (5.24.0)
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.16.9-gentoo x86_64
Windowing System: X11
Distribution: "Gentoo Base System release 2.8"
DrKonqi: 5.24.0 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

Logging in after my monitor entered sleep mode.

I have a feeling this is relating to DisplayPort, as from what I can tell whenever the monitor goes into standby, unlike DVI or HDMI, the monitor appears disconnected to my system (the monitor does not appear to relay connectivity details).

I believe logging back in to Plasma before the DP monitor resumes from standby is what causes this issue.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
