i was thinking about switching to wayland when they give support to legacy nVidia devices (Phobos, Deimos, Mars, some other ones i haven't acquired/rescued/resurrected yet but will in the unforeseeable future). How's your experience with it so far?
No experience with Nvidia whatsoever. Haven't touched their hardware in my life.
Wayland in general is pretty good. There's basically 3 of it:
1. Gnome. Relatively isolated and monolithic, but quite stable for that. If it works, it works great. With the downsides being your well known gnome caveats: high resource draw, bad customization, opinionated workflow. I'd compare it with using a Mac.
2. KDE. Buggy like KDE plus what Wayland was 5 years ago. Stay away. That applies to kde in general too. But especially kde with Wayland.
3. Wlroots (everything else). Technically hyprland, sway, river, etc are all separate implementations of the Wayland spec - but they all use the wlroots library as a base and the config files are a similar format. Things you would xset in your .xinitrc are all doable via the config file, and it also does shell commands for things like tray daemons. Unless you insist on compiling your own WM every startup (think DWM/Xmonad), these are great. Sway has the largest ecosystem and is probably the most stable, hyprland is flasher. I don't have significant experience with the others but they seem chill.
iirc there's nouveau builds of sway and hyprland in the AUR - those might be worth trying.
Thanks for the ask!
