X because when I try selecting Wayland from sddm the screen goes black and then takes me back to sddm. I'm on manjaro and I've done no configuration and I've not attempted to install Wayland I just assume because it's an option in my drop down that it's been installed.
I had plasma-wayland-session already installed. It turns out I needed to add nvidia-drm to the kernal params and forced GBM backend. After that it seems to be working. I am a wayland man now!
I understand and X works fine for a lot od people but do remember the number of developers maintaining it have been dropping year on year. No harm in trying IMO. If you are on Plasma or Gnome, you get a simple switcher on the login screen.
I have to add that the switcher is not on Debian 12 by default, where Wayland support for Plasma is optional in plasma-workspace-wayland. Also, it is broken on Nvidia due to missing packages/libraries and Nvidia's proprietary driver still in general not supporting Wayland properly.
Wayland!
It has advanced a lot lately, I've been daily driving it for months now with no issues, compared to a couple of Plasma versions ago where it would break itself in 5 minutes lol.
Only thing I'm missing is a good remote access solution. I'm currently making do with Sunshine + Moonlight but it has the very annoying bug of not showing the mouse cursor.
Edit: lol just realized this post is 1 month old. Really looking forward to Lemmy fixing this bug.
