Have been running Wayland on Fedora for a couple of weeks now. No Problems so far. But no real benefits either. I’m using 3 1080p Monitors connected to a Laptop. Intel Integrated Graphics. Wayland seems a bit more consistent in terms of display switching between docked Monitors and internal screen, that’s it. You loose redshift and color pickers (the big ones for me personally). And i can’t remap my mousebuttons/scrolling like i normally do for my trackball.
At home, i run on nvidia, so wayland is a big nope.
As someone who consistently is running 2 or more screens, often mixed resolution, dpi and refreshrate, wayland would provide major benefits, if nvidia would support it. I truly believe that wayland will be the future. The current problem is, that the benefits are only felt by very few people. You basically need to be running something that needs mixed dpi, mixed refreshrate, fractional scaling or something like that and not be on Nvidia. And even then you are currently making some sacrifices. Since 1080p is still the majority and most people aren’t rocking 144Hz Screens or more than 2 displays where they’s care for perfect scaling (especially on Linux), most won’t need wayland.
So for now: If you aren’t on Nvidia, give it a try. Chances are you won’t feel a difference. If in doubt, use X11 and watch wayland progress from the sidelines. Wayland will get there. It’s just a very integral and big part of our systems to replace, so it takes time. Especially when all other components need to adapt to it.
