Description Martin Jørgensen 2025-06-30 19:45:07 UTC
I recently updated my system, got this error message described in this source (https://www.spinics.net/linux/fedora/fedora-users/msg528992.html)

I applied this solution from this source (https://discussion.fedoraproject.org/t/my-update-doesnt-go-through-because-of-a-vlc-conflict/156696/3), but this did not fix anything (as far as I could tell).

I changed from akmods-nvidia to akmods-nvidia-open using the commands below from this source (https://rpmfusion.org/Howto/NVIDIA#Kernel_Open)
sudo dnf install rpmfusion-nonfree-release-tainted
sudo dnf swap akmod-nvidia akmod-nvidia-open

This did nothing as far as I could tell.

The final solution was this simple.

cd ~/.config
tar -c plasma* -f plasma.tar
rm -r plasma*

This got me a stable plasmashell.

I then got the error that software rendering is in use. I clicked the "Defaults" button, which set the renderer from "Software" to "Automatic".

I applied the setting, logged out and back in again. Now everything works.

This is my dnf history list:

Reproducible: Always

Steps to Reproduce:
1. Latest update 2025-06-24
2. Attempt update, get error about conflicting vlc-plugins-{base,freeworld} files??
3. Update using dnf -x "vlc*"
4. Watch as plasma indefinetely crashes
Actual Results:
Plasmashell crashes three times
Crash Handler starts collecting data using gdb (~6GB memory usage per gdb process).
CPU avg 9.9 something
10 more Crash Handlers for plasmashell spawns
59/64GB RAM in use while gdb crash handling

Expected Results:
Logs in and get stable plasmashell

Comment 1 Martin Jørgensen 2025-06-30 19:51:42 UTC
Forgot to mention that in Settings > Input & Output > Screen Edges I had configured the top left corner of my screen to "Overview".
During the indefinite crash of plasmashell; if I moved my cursor to the top left of the screen, KWin crashed.

During my debugging session, fortunately I had KRunner available, but (I assume) that when I was using KRunner, gdb was running in the background, so that crashed aswell.

Also forgot some details about versions. So fastfetch to the rescue:
