river, a non-monolithic wayland compositor (codeberg.org)

An important difference between Wayland and X11 is that Wayland by concept combines window manager and compositor. That made it harder to write simple or experimental window managers for Wayland, such as StumpWM or i3.

River is a compositor for Wayland that supports implementing a window manager separately, with an independent window placement paradigm, in an arbitrary language.

Here is the wiki page listing window managers for river:

The ones I find most interesting are mousetrap and mopotamo - I am a big fan of StumpWMs manual tiling and configurability.

I like river WMs like Niro on my laptop. It doesn't work for me on a multi monitor setup, though.

You mean Niri? I do use it with 2 monitors, and very different ones (one 32" 21/9 1440p and one 14" 16/9 1080p) without any issue

What problem do you have?

Haha autocorrect fail.The multi monitor setup was on a work machine. My work is a completely different workflow. Niri worked perfectly.
