2025, the year I switch from wayland to Xorg.
Why? Because I bought a new screen.
Huh? Well, I don't know either.
Plasma 6 on wayland worked fine with my fullhd-screen. Yesterday, I powered the box down, switched to my new hi(gher)dpi screen, powered it on, got the bios post, boot messages, and a black screen instead of sddm. An hour later I found that sddms wayland support is experimental still, so I switched it to X, and got a black screen when my plasma-wayland session was to start. So, switched to plasma-x11 and everything is fine.
Other compositor (tested sway) are fine.
Don't know if it's nixos or plasma, I'll probably try a live usb later.
So yeah, it's the year 2025 and I'm on X. Well, could be worse, could be the other X.
