Wayland. It comes up a lot: “Bug X fixed in the Plasma Wayland session.” “The Plasma Wayland session has now gained support for feature Y.” And it’s in the news quite a bit lately with the announcement that Fedora KDE is proposing to drop the Plasma X11 session for version 40 and only ship the Plasma Wayland session. I’ve read a lot of nervousness and fear about it lately. So today, let’s talk about it!
No it means that a single distro won’t, by default, use X11. You are free to install it yourself if you choose to use that specific distro.
It doesn’t say anywhere that KDE won’t support X11…
Also the fact that Nvidia works so badly in so many scenarios on linux is 80% of the fault of Nvidia, not KDE…
