I have a single monitor connected via DisplayPort (AMD video card). Keyboard and mouse are connected via USB. If I set the power settings to automatically turn off the monitor by timer, and the time expires, or if I turn off the monitor forcibly using a keyboard shortcut, the monitor turns off first, and then turns on again after a few seconds. After this, opened application windows and the plasmashell looks normal on the screen and update their contents, however, applications do not respond to the keyboard and mouse, but the mouse cursor moves normally. It is especially strange that I cannot switch to another virtual console (tty) by pressing Ctrl+Alt+F1..8, but I can reboot using kernel command (Ctrl+Alt+PrtScr+REISUB). STEPS TO REPRODUCE 1. Start the Wayland session 2. Set keyboard shortcut for "Turn off the monitor" in the System Settings 3. Press it OBSERVED RESULT See above EXPECTED RESULT Keyboard and mouse input works.

Pushed by zamundaaa into branch 'Plasma/5.23'. platforms/drm: remove the dpms filter when outputs are added When the dpms filter is active and an output is hotunplugged, or is momentarily detected as hotunplugged, adding a new output should remove the dpms filter again.
