Bug ID: 489655
Summary: Plasmashell core dump upon screen layout change
Classification: Plasma
Product: plasmashell
Version: 6.1.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: andrea.i...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
I use a laptop and an external monitor.
The laptop is powered with a wall adapter that has two USB-C outputs: one of
them goes to an Anker 8-in-1 USB-C dongle, where I connect my wireless
mouse+keyboard USB-A transmitters, external monitor HDMI cable, and which also
acts as a power delivery "relay" for my laptop, as it ultimately provides power
to it via USB-C.
For whatever reason, when I connect another device to the second USB-C output
of the wall charger, the Anker dongle must detect a brief drop in supplied
power, and briefly disconnects the external monitor (I think it doesn't have
enough juice to power the HDMI chip).
This only lasts a couple of seconds, during which I can see that Plasma goes
back to single display mode (i.e. all my apps and "main display" taskbar move
back to the laptop display).
All fine and dandy until this point. When the brief power shortage goes away,
Plasma again tries to restore the dual monitor setup, but here's where it
crashes. I can tell because I initially only see the wallpapers on both
displays, and the empty space for task bars is filled in a while later.
Core dump is attached. I haven't heard from DrKonqi for this one, maybe it
would've detected it's a known issue.
