The fact of the matter is that Xorg still works beautifully for 99% of people out there while Wayland still has teething issues even though it was meant to be THE BEST GRAPHICS SYSTEM IN THE WORLD EVAR. But that will surely change - we just have to wait a few more years. Ten will be enough I guess. Right? 22 years of development must surely be enough!
What Wayland fans fail to realize is that you don't swap something which is working fine for absolute most people out there with something which still has a ton of issues and corner cases and requires special graphics drivers and which doesn't work well or doesn't work at all with NVIDIA.
And to add insult to injury Wayland requires a ton of work/code from the environments which want to work with it that's why XFCE/IceWM developers have simply ignored it so far.

So the 99% assessment is not accurate. The correct assessment is 40% on open source support graphics. I have not corrected for the ratio between Nvidia and open source supporting hardawre in use(Amd and Intel) But the number does not land a 99% no matter how you run it.

The objective of GDM was to end up with the single thing managing the graphic card buffers be you in text mode or graphical.
EGLstreams still leaves you with the problem where framebuffer can come into dispute with normal graphical output.

I made a correction to the original post.Last edited by mppix; 28 April 2020, 09:54 PM.

As of Gnome 3.36, Wayland is flat out better. No blinking, no tearing, responsive, and so far rock stable (stability needs long periods of evaluation).
There are still things to improve (see original proposal for Gnome 4) and we are still in the transition phase. Some of the benefits will also only become clear down the road when applications pick up the benefits and we can start removing the compatibility interfaces of the old stuff.

Originally posted by ColdDistance View PostSorry if I'm inopportune, but today the only thing I can't do with Wayland is screencasting. I use GNU/Linux for all my tasks: programming, virtualisation with VirtualBox, gaming, common desktop tasks (web navigation, music, video, Prime Video, etc) and I feel it very good. I use Wayland on my laptop Acer Aspire A515-54 and DiRT Rally works stabler on XWayland than Xorg (I had a few hangs on Xorg).
Obviously, to see old applications working on XWayland is not ideal, but the day when OBS works properly on Wayland I can fully migrate. I hope with the passage of time to see the applications migrating to Wayland and see XWayland only patched for some old native games, because Wine games could work better if Wine runs natively on Wayland.
Today I use Wayland on my laptop, but on my desktop, where I do screencasting, I still keep Xorg.
The problem with NVIDIA is NVIDIA's fault to no matching its driver with the standards for the Linux graphics stack.
To me, it doesn't matter if Xorg is doing better or worse than Wayland TODAY, since atm we can choose to use both of them depending on our needs, but eventually and just because there happens to be a general interest into switching to Wayland, Wayland will be the default. In the meantime you choose the hell you rather working with and that's it.
In my case, I use both, Gnome+Wayland on my laptop, Sway at work, Gnome/Plasma + Xorg on my desktop so I can use my Nvidia GPU to play CSGO.

birdie have you ever used gnome with wayland ? it is much snappier and "micro tearing free". At the moment I have a navi 10, multiple intel igpu running on wayland. and a nvidia quadro t1000 running on gnome with x11. even with the latest driver 440.82 and full sync pipeline thingy on the x11 gnome is less smooth then all the other cards with wayland - even the igpu on the very same device is snappier. Of course if I switch back from wayland to x11 I have the same behaviour on amd and intel aswell. This are different rigs and different distros. I'm very sensitive to microlags, stutter etc fps ...but some people arent so maybe you are not able to recognise it?
