I could see MATE going Wayland only before XFCE does. They are a “traditional” desktop but not committed to old tech in general. Their whole system has already been ported to Wayland when used with a compositor like Wayfire or LabWC. As a small project, they may not want to maintain both longer term.
Lots of MATE users on other UNIX systems though. Not just BSD but Solaris and such. So, who knows.
XFCE is building libraries to make supporting both longer term easier. So, they should support X11 for a long time. We will see what happens if GTK5 is Wayland only.
Trinity Desktop is probably stuck on X11.
And most X11 window managers will remain X11 window managers forever. The only reason Sway exists is because i3 is not moving. There is Wayland Maker instead of WimdowMsker and DWL instead of DWM. This list goes on. What non-DE x11 window manager is porting to Wayland? I cannot think of one.
But Plasma is not ditching X for a year or more. And many distros will ship the X version far longer. The freaking out seems more like a political statement than a pragmatic requirement at this point.
If Debian Forky ships Plasma with X11 support in 2027 (and I bet it does), the first version of Debian Stable to ship Wayland-only Plasma will be Debian 15 in 2029/2030. Many, maybe most, never-Waylanders will have migrated to Wayland by then.
Um.
First, I am not trying to recruit you to Wayland. Do what you want. I am responding to your demand to explain what is better about it and your implication that the answer is “nothing”.
Apparently you like Xorg. You like it enough that you see nothing better about Wayland. Given that, getting bent out of shape about the word “fan” appearing in my response is a bit excessive. Protest too much? Christ.
And I did not even apply that term to you specifically. I just answered your bloody question. A question that was grumpy to start with. Grace you say?
Finally, I have been using Linux since well before 1.0 when I had to spend all night on a Sun workstation downloading floppy images. And half the next day guessing mode lines for my monitor to make XFree86 work and fixing build scrips for whatever I was trying to run on it. I moved straight from OS/2 to Linux though I installed BSD/386 before that. I own both SGI and Sun (Solaris era) hardware.
My preferred Linux distro does not use Glibc, GCC, GNU utils, or systemd.
I doubt if there are many Linux technologies you have encountered that I have not. So I am not sure what point you think you are making.
That said, it sounds like you used Ubuntu a whole lot more than I did. I better walk around these egg shells before I ask if you liked it.
