Continuing the discussion from Display returning irregular (or not at all) after screen turns off:
@Aragorn After applying the 2025-05-14 update for Plasma 6.3.5, I am still having the same issue specified in the OP: using Wayland, when my monitor turns off for any reason, whether on lock screen or on my desktop, the display will fail to come back up: monitor does not detect a connection and screen remains blank, monitor will go back to auto-sleep. I have to restart [the VM] for it to come back up.
Any thoughts on next steps or what I can check? I’m not really sure where to start if the Plasma update didn’t address it…
