New crash information added by DrKonqi
plasmashell (5.27.5) using Qt 5.15.8
Plasma crashed the instant I clicked the app menu button. It started doing this a couple days ago. The crashes happen a few times a day.
Just grasping at straws, but I think this started after I created /etc/X11/xorg.conf.d/20-nvidia.conf to correct a scaling problem. I have nVidia's graphics driver installed; the driver doesn't work with Wayland session so I'm forced to use X11; things built with QT become scaled up about 50% with this configuration (and the global scale setting becomes ineffectual on QT things); 20-nvidia.conf forces QT things to be scaled at 100%.
contents of /etc/X11/xorg.conf.d/20-nvidia.conf:
Section "Device"
Identifier "Default nvidia Device"
Driver "nvidia"
Option "DPI" "96x96"
Option "UseEdidDpi" "False"
EndSection
I can't think of anything else I may have done. I do not believe the crashes started right after I installed the nVidia driver.
Hope this is useful! Happy to provide more info.

In general Plasma has been reliable, etc. Here's a list of scenarios where I've seen these crashes: - Alt-tab between windows - Change focus to different window with mouse - Start video playback in firefox (youtube in most cases for me but occassionally plex web client) - During video playback in firefox (youtube in most cases for me but occassionally plex web client) - Open launcher menu (mouse or 'windows key') - KVM switching to or from this machine -- I run triple displays with 2 on the KVM. One of the displays is always connect to my machine -- This machine has a duplicate (not identical) set of input devices (keyboard, trackpad, etc.) which do not switch away with the KVM - These crashes occassionally happen without any activitiy that I am aware of The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault PID: 3774 (plasmashell) UID: 1000 (kd7gab) GID: 1000 (kd7gab) Signal: 11 (SEGV) Timestamp: Wed 2024-01-24 08:15:24 PST (37s ago) Command Line: /usr/bin/plasmashell --no-respawn Executable: /usr/bin/plasmashell Control Group: /user.slice/user-1000.slice/user@1000.service/session.slice/plasma-plasmashell.service Unit: user@1000.service User Unit: plasma-plasmashell.service Slice: user-1000.slice Owner UID: 1000 (kd7gab) Boot ID: d5b137e462ae4c5e9912cf7e2c8514cd Machine ID: 56098dad05824b7fbf31e840d5164906 Hostname: jondeb-desktop Storage: /var/lib/systemd/coredump/core.plasmashell.1000.d5b137e462ae4c5e9912cf7e2c8514cd.3774.1706112924000000.zst (present) Size on Disk: 66.7M Message: Process 3774 (plasmashell) of user 1000 dumped core.
