Bug ID: 498531
Summary: Plasma crashes after swapping display port inputs
Classification: Plasma
Product: plasmashell
Version: 5.27.11
Platform: FreeBSD Ports
OS: FreeBSD
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: rmdegenn...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.27.11)
Qt Version: 5.15.16
Frameworks Version: 5.116.0
Operating System: FreeBSD 14.2-RELEASE amd64
Windowing System: X11
Distribution (Platform): FreeBSD Ports
DrKonqi: 5.27.11 [KCrashBackend]
-- Information about the crash:
Always, after booting up FreeBSD, only one monitor is active. I have two HDMI
monitors plugged into two display ports; this happens regardless if a KVM is
used. After logging in, with one monitor displaying anything, I've tried lots
of things to activate the other monitor. The only thing that works is
unplugging & swapping the cables between display ports. I then run xrandr
--listproviders, and the other monitor is activated. I then swap the cables
back. This is when plasma sometimes crashes. BTW, this happens on FreeBSD &
Kubuntu; though I didn't stay on Kubuntu long enough to see crashes, just
confirm the monitor weirdness. If it is helpful, the monitor weirdness also
happens with XFCE on FreeBSD; though again I did not use it long enough to see
any crashes, only replicate the monitor issue.
The crash can be reproduced sometimes.
