Plasma desktop crashes when monitor turned off

[Lubrigant3]

I have just registered on the forum. I have little experience with Gentoo, but more or less, I think I'm getting the hang of it and my transition is not being as traumatic as I thought; even so I'm having some problems, including one that I don't know if it's the same as the one discussed in this thread but if not, it sounds very similar. So before opening a new thread I've taken the liberty of continuing this one. If you think it's not appropriate and I should open a new one, let me know and disqualify it.

In my case, Plasmashell stops working when I resume the session **with the monitor off** (I only have one monitor). If I first turn on the monitor and then flip the switch on the computer, the session resumes fine.
I've tried with a clean test user, and the same thing happens, so I'm ruling out a possible corruption of some configuration file of my regular user. I don't know if I'm right.
I'm also having some problems with SDDM that I'll check in another thread, but I don't know if they have anything to do with it because when I start the graphical session with `dbus-launch --exit-with-session startplasma-wayland` the same thing happens.

I'm in Plasma 6.2.5, KDE Frameworks 6.10.0 and Qt 6.8.1


Thank you.


P. D:
I forgot to mention that launching Plasmashell from Krunner works the first 2 or 3 times I come back from a suspended session. A while after the first restart of Plasmashell Krunner stops working to execute commands and only from a Konsole window I can execute `plasmashell` or `plasmashell &` , without ` --replace` since it doesn't work anymore either even from Konsole.

Sorry, I forgot you were running a Pi5.
My Pi5's only have twm and dwm, they're essentially running a headless images for some docker apps. This does work and should be comprehensive enough to stop any "autoconfig", I left in the details for the second monitor because it's easier than writing it again if someone else needs them, you can ignore/delete them. The modes listed are for my monitor, the 60Hz one will probably work but you should update them (you can pull the relevant EDID data from Xorg.0.log, xrandr, or use one of the EDID readers in portage), though it may work if you remove them altogether (and references to them) but I can't test that so left them in.
