Wayland is actually pretty stable. Nvidia has problem with OpenGL in Xwayland (i.e. 3d accel for x11 apps), otherwise, it should work.

There are warts though, when using Wayland. When using scaling (doesn't have to be fractional, either), X11 apps are being upscaled, not downscaled, resulting in blurriness. Unfortunately, neither Firefox nor Chrome does support Wayland natively, and who wants to use their most used app on their computer in blurry mode?

Must admit I don't understand what Wayland is, or X server for that matter. Would someone mind explaining it, for someone a bit dull of mind as myself?

In short: X.org is a decade old display server that became the standard to display graphical window on the majority of Linux distribution. GNOME, KDE, XFCE and others are/were client to this display server.

Wayland is a new protocol where the window manager (ie GNOME, KDE,...) is responsible of directly managing the display. Each window manager must reimplement this protocol (or use a library already doing this work) which enable them to have more control over the windows.

Applications must also directly support Wayland like they did for X.org before (which was the default commonly used, so no problem) or the user just have XWayland installed on their computer to show X.org windows inside a Wayland WM but then the application may not display correctly (blur, artifcats,...)

It is perhaps worth noting that while X.org is about a decade old, it is an implementation of the X Window System protocol which dates back to the mid 80s.

Suffice to say, quite a lot has changed in computer graphics/interfaces since that time, and most modern *nix operating systems end up circumventing quite a lot of X to offer modern features. Thus X brings quite a lot of legacy debt to the table which can't be easily removed.

Also, even back in the day, X wasn't considered the best tech around, at least by some. For example: https://en.wikipedia.org/wiki/NeWS was around.

However NeWS' licensing was proprietary and X won out.

Gopher and HTTP had a similar situation. Gopher had a lot going for it, but the future licensing situation was unclear. HTTP was free, clear, and widespread by the time Gopher became GPL.

After 10 years of work you still can't do much useful unless you run X and shim it with XWayland. "Stable" is a strange descriptor given this context.

[vetinari]

"Stable" and "popular" are two different concepts. Yes, some apps and frameworks didn't bother yet with the switch. Some did, Qt5 or Gtk3 are fine.

Firefox has recently added wayland support, it isn’t enabled by default.

[vetinari]

It doesn't play nice with OMTC, or 3d accel in general (see EGL bugs in bugzilla), and has problems with scaling and input. It is a work in progress, that's why it is disabled.
