Unfortunately that doesn’t work, the best I can get is the screens wake up and I get a black screen with a mouse cursor. I then have to restart sddm for anything else to work

It used to be about 50/50 now it fails 100% of the time

Do you also have an Nvidia gpu?

It’s definitely not that for me as I’m on Nvidia!

Yes that’s pretty much it, there’s a strip around 3/4 of the way down both displays that has white line flicker across it whenever there’s any movement on either screen.

Yeah I’m definitely above the relevant versions for kde and Nvidia

That’s a good idea, I’ll try the endeavour OS live environment as that should be close enough to my setup

How would I tell if that’s the case? And I guess there’s nothing I can do about it if that is the cause?
