Wayland works very well now. And for the last several years.

Give Gnome on Fedora a try. If you have an AMD or Intel GPU Wayland will work great. I'm not sure where their binary Nvidia support is at, and I haven't tried it with Nouveau.

For some peoples value of "very well". For those who need accurate color on the other hand, not so well at all ...

yeah, for me the show-stopper being lack of primary clipboard.

This was implemented couple years ago: https://fedoraproject.org/wiki/Wayland_features#BLOCKER:_...
Any real blockers?

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.

I've used it. It was hell. Mostly I blame Lenovo for wiring up the P50 in this entirely idiotic way, that makes the external display ports only visible to the NVIDIA graphics card; and NVIDIA, for well documented reasons. Nonetheless, the seemingly endless series of poorly documented software named after children's toys has left me shaking my head in disappointment at what the world has come to; and I fled back into the arms of a disabled Intel graphics card and Xorg, which has left me with problems that are merely massively irritating (awful performance, constant 22 W power consumption and only semi-regular lockups), rather than those that left my laptop entirely unusable.

Well, actually, wiring the Nvidia card to the external ports makes a lot of sense.

Not great for Linux currently, but in a world where the drivers worked for everyone it would be great.

By connecting the high power discrete card to the external port, it removes the copy latency Optimus has and does it in the case where the laptop is most likely plugged in. It also allows the Nvidia card to directly control the port, which means G-Sync is possible. I don't know if they enabled it, but it is possible.
