I just installed Wayland about an hour ago or so in Bullseye, and it works fine. I've been wanting to use it for a while now but after having read all those posts and articles claiming that "it's not ready yet", that "there are bugs here and there" and given the fact that Xorg just works, I simply didn't, till now. While in Xorg, I wanted to play a video in VLC and it didn't work; I got sound but no video, however, the video plays just fine in mvp. I launched VLC via terminal with the video as input and got this
radeon: the kernel rejected CS see dmesg for more information a web search on that error led me to a post about some issues with radeon and Xorg, it was on BSD though
https://forums.freebsd.org/threads/xorg-do-not-work-with-amd-again.70531/, but I started to wonder if that could be the case, so installed Wayland, switched to it, tried the video in VLC and it played this time without any issues, so maybe there's something weird going on that I'm not fully aware of. Then I came here, hit the search button, typed "wayland" because I wanted to know who amongst some of you guys already use Wayland and well, here I am, sharing my 1-hour experience ... plus a few minutes lol
Performance is faster and it seems as though it uses a bit less memory.
Responsiveness seems slightly better yeah, so far, but in my case it uses a bit more RAM, like 100mb more.
I'm using KDE Plasma by the way and had to install the pkg
plasma-workspace-wayland logout and then login selecting the Wayland session in SDDM.
