I’m on Solus Plasma. It’s worth noting that this never happened on Solus GNOME which I was driving for a few months before switching to KDE.
So this doesn’t happen every time I shut down, but it’s pretty frequent. What usually happens is I initiate shutdown (using either KRunner or from Application menu clicking shutdown). The monitor and keyboard and mouse switch off, but the CPU does not. Fans are running, RGB is on. I can’t wake it up with any keys. I can only long press power button on the cabinet to force shutdown.
Couple of things I observed:
-
I noticed sometimes my external HDD was not auto mounting when I started the PC, so I thought maybe it was automount that was preventing shut down also. So I tried to see if the times automount didn’t work, coincided with the times I had to force shutdown - they don’t. Even if it shuts down without issues I sometimes notice automount not working. And not every time I force shutdown I have automount issues.
-
I thought maybe clicking the shut down immediately button on the confirmation screen is what is causing the issue. I tried letting it shutdown on its own after the 10s countdown, but that also yielded inconsistent results.
I’m at a loss for what to do now.
You say that even automount causes problems. You should look for a backup HDD before data loss. You should read out the SMART values.
Either way, disconnect the external HDD from the PC and check whether shutdown still causes problems. At least I know the problem myself from problems with external storage.
Either way, you can only guess without any information. Logs would be more helpful.

journalctl -b -1

systemctl --type=service --all |grep runningI don’t think this is just a KDE issue as I’m having it on gnome too. Not sure how to fix. I feel like it happens less when I close all background processes before shutting down but idk.
It might be due to display drivers not playing nice on wayland; I’ve had this problem a couple months ago on arch with the amdgpu drivers, using either one of sway, labwc, or KDE. It did not happen on Xfce, though; and after a kernel update the problem subsided.
Btw Months ago… At that time it wasn’t that long ago that the big DE’s started to implement wayland in the first place to get rid of xorg. In the meantime, wayland is running pretty well.
