Primary Monitor Power Cycles (Wayland)

RoobertDoobert · 2025-04-29 19:47:05

Hello, I am having some new issues with my arch boot, my main monitor seems to be power cycling on Wayland, but seems fine on X11. I prefer to keep using wayland, so im looking for advice on how to fix the power cycle.

^ is what I found when pulling the systemd, from monitor connection, to disconnection.
