Wayland seems ready to me but the main problem that many programs are not configured / compiled to support it. Why is that? I know it's not easy as "Wayland support? Yes" (but in many cases adding a flag is enough but maybe it's not a perfect support). What am I missing? Even Blender says if it fails to use Wayland it will use X11.
When Wayland is detected, it is the preferred system, otherwise X11 will be used
Also XWayland has many limitations as X11 does.
But why would the distros do that? It takes effort and has real costs for them.
They're already starting to go that way, in a couple years Linux mint is even going to support Wayland. Ubuntu and fedora has already defaulted to Wayland. Fedora is actually deprecating xorg in a few releases. Budgie wants to have full support next year.
There isn't much more than the testing they already have to do every release. Infact not having to support legacy code will free up resources for the whole Linux community as well as cutting the time in half for validating packages on distros. Every package that runs on xorg also runs on wayland, they have to test both.
Granted some have custom tools they'll be working on but it's going to be a while before every major DE supports Wayland. I'm curious, you think the distros have to implement their own version of Wayland?
Nope. They do have to test their own shit.
Why make a change when one can just not?
Considering that Ubuntu, Fedora and any distro with Gnome or KDE as the default DE already come with Wayland as the default, it is clear they have been testing their own shit when it comes to Wayland and then shifting to Wayland by default.
This is a thread about slow uptake by programs of Wayland.
X works for me.
Well it was you who implied that a distro shipping the DE with wayland has to do extra testing that they don't do. I just replied stating that distros are testing and validating for wayland to be the default.
Good. No one is stopping you from using it.
