Supporting virtual reality displays in Linux

That's a great page... but it sure would be nice if there were some sort of date or other indication of how "up to date" it is. Note for primary selection it does say "Proper wayland protocol upstreaming is still pending" but I don't know what that means for the average user.

After primary/secondary selection, for me the missing parts are per-app (not full screen) remote window display and NVidia support (when I tried to use GNOME on Wayland in Ubuntu 17.10 with my NVidia GeForce 8400GS (I know it's old but all I do is programming, not gaming--it's good enough to run two monitors) the video seemed jerky and I had problems with some apps--of course now I can't remember what they were. Remmina? Videos in Firefox? Something I needed).

I know it wasn't just my imagination because I honestly didn't realize that my desktop had been set to use wayland by default when I upgraded from Ubuntu GNOME 17.04. It wasn't until I noticed these issues and went poking around that I found this setting; changing back to GNOME on X solved my problems.
