--- Comment #4 from Josh Medeiros <josh.a.medei...@gmail.com> --- I have a similar issue, but it happens after the monitors are off for a couple hours. One monitor wakes, the backlight comes on, the OSD says "DisplayPort: No Input", and the monitor goes back to sleep. Then the other wakes and does the exact same thing, then back to the first in an infinite loop. This continues until I wake the system. On logs I see massive spam from kscreen_backend_launcher every 5 seconds, which is the same interval as the monitors waking. When I wake screen kscreenlocker is broken - the background is there but no greeter, impossible to log in. I can open a TTY but loginctl unlock-session does nothing, nor does killing kscreenlocker. The best solution I've found is to kill sddm, but this starts a new session I lose everything I had open. Probably a second bug, but it happens 100% of the time after kscreen_backend_launcher starts waking the screens, so likely related in some way. I can also reproduce windows moving by running xset dpms force off and then waking monitors immediately after they power off. For me everything goes to my second screen but I think this is just GPU port order (plasma defaults to my second screen on a fresh install too).
