Every year I read a comment saying Wayland is standard, I try to switch to it and always regret. Literally most day to day functionality doesn't work, electron only recently added screen capture ability, and that's only for current window, not full screenshare or another window, so pair programming is pain, running Java or C# desktop programs is pain or impossible due to scaling issues. Vulkan/OpenGL programs can crash after restoring from minimised state... Switching from multiscreen(docked) to single screen(laptop) doesn't restore windows in their position, oh even dragging windows between monitors doesn't work well as the window on a new screen is different size, eg. just the top bar with the window content gone until minimized and maximized again

Screen sharing is still a awful yeah. It either just works or you’re into a world of pain with user level systemd units that log nothing useful or nothing at all, dependencies that you have to somehow know to install with no instructions, arcane program arguments and env vars that mean hacking desktop files or shell scripts for things that are otherwise straightforward and then random breakages with upgrades.

I still class it as "bleeding edge". In another five years I doubt it'll be in a state that'd make me recommend it as the most sensible default. Maybe, maybe by the end of the decade.

Servers don't have GUIs and Android doesn't use Wayland so do you mean cars?

It's the compositor used on the Steam Deck.

I guess it was meant as a joke.

if you'd develop an embedded OS e.g. for cars, why would you use X11 in this day and age?

I would expect them to invent some janky custom thing running on fbdev.

Not sure whether you are aware, but car manufacturers were one of the earliest adapters of Wayland for embedded use cases.

Many servers have guis.

No and unlikely to be in any forseeable future
