Using wayfire (disabling the fancy resources eating plugins) + waybar + plus a bunch wlr utilities (some from sway).

I'm using integrated intel gpus. There's a laptop with both the integrated intel gpu and a nvidia discrete one, but I had to configure the bios to only use the inegrated one, both the binary nvidia drivers, and the open source nvidia drivers fail to set fbdev=1 (the external hdmi monitor is the one associated to the nvidia gpu, and it gets a blank screen), which is required for enabling KMS, which is required for wayland, so no luck. Nouveau actually works, but it's not stable enough, after some time of use the monitor turn off and there's no way to turn it back on, and it feels slow or lagging compared to the intel gpu, although it should be the opposite. So I gave up on nvidia on that laptop, and any other box only has the integrated intel gpu anyways. I've read of successful stories with nvidia, both with the binary and the open drivers, but I think it's not a generic thing that all nvidia gpus will work well on wayland with nvidia drivers. The noveau drivers are the only ones working for some gpus, but not stable enough. So I stick with the recommendation to stay away from nvidia if using wayland...

I guess although WM still applies, on the wayland jargon they're called compositors, and the wayland compositors are not as light as the Xorg WMs, since there's no Xorg server, and part of the responsibility of the server goes to the compositors on wayland...

There's labwc, which is the compositor I would have chosen, but the developer decided to stick with xml configuration equivalent to the the openbox one, and also with the openbox themes/styles, which I never liked. On Xorg I used fluxbox + tint2 + ..., and I tried openbox, but totally disliked it compared to fluxbox... But other than config and theming, I like its idea of being a light compositor.

Actually by disabling the plugins I am on wayfire, it's pretty much labwc but with new decent config (I really like its config BTW), and using the gui toolkit theming, so no specific wayfire theming at all, which is nice, as opposed to the labwc own theming... Still, labwc is also an option for some.

Wayfire and labwc are not tiling compositors as most of all others, :)
