Description Steffan 2025-01-17 19:09:24 UTC 
Fresh boot, displays detected, then both shutdown and apparently get in a connect/disconnect loop

2 monitors under KDE Wayland, every time I start one monitor fails shortly afterwards. Both monitors only work again when reconnected. If I then restart the computer, one monitor fails again after approx. 4 seconds and I have to reconnect the two monitors again to make them work.

I'm afraid we need a lot more information tp proceed. Please answer the following questions:

1. What's the model of screen? Are they both the same or different? What are they?
2. What version of Plasma are you using, and on which distro?
3. Is this seen in only the Wayland session, only the X11 session, or both?
