As much as I want to support the idea of a well supported, modernised graphical protocol system, wayland simply isn’t ready yet. There’s so much shit that simply doesn’t work, and they’re all made up of little niche cases that will take substantially longer than a few months to resolve, and I still haven’t seen anything that suggests Wayland has a practical equivalent to xorg.conf.
Is Alma Linux rolling their own version of Plasma with x11? Or are they just sticking with an older version of Plasma? Is anyone else planning on hacking x11 back into the DE?
Wayland development continues to push forward. Currently it works better than X11 in 95% or setups, and it won’t be long before it covers 99.5%. X11 is legacy now, and Wayland works perfectly for the vast majority of users and is only improving. The time to move on is coming.
For legacy use cases there will be an alternative X11 DE you can use for a long time yet.
There are few Wayland only apps today. But as the percentage of Linux desktop users on Wayland goes over 80 percent, that will change.
And today, GUI toolkits and desktop environments have to limit features to those that will work in both environments. But not for long.
My guess is that it will be totally impractical to use an X11 only desktop 3 years from now. 5 for sure. In fact, I bet few people will even have Xwayland installed 5 years from now. To run what? Xfig? Netscape?
But certainly it will still be possible to run an X server. Xorg itself will still probably run fine. It already uses KMS and DRI from the kernel and those may not change much. And I am sure at least a few zealots will still be pushing XLibre a decade from now. And Wayback will almost certainly let you run an X11 desktop for many, many years to come for those “legacy use cases” you talk about. Like running CDE for a couple of hours.
Probably the most interesting development has been Phoenix. They have floated the idea of having an X11 first environment (eg. using an X11 window manager) that can run Wayland apps too. If that actually happens, I am sure it will find some fans. If you have spent 15 years fine-tuning your FVWM or Xmonad config, you won’t want to give it up.
It will be interesting to see where the BSD world goes with all of this. I think FreeBSD will go Wayland. But NetBSD and OpenBSD could be x11 holdouts. But the Wayland-only app problem will impact everyone. Time will tell.
