niri could benefit by either prioritizing uwsm for session management or fully delegating this responsibility to it.

uwsm effectively addresses many issues related to systemd integration in a clean and universal way.

The specifics of different compositors are handled via plugins, in the form of small, easy-to-maintain shell scripts.

What benefit would this be to niri? We already integrate systemd, it works fine.

This would fix the systemd integration on NixOS. Moreover, I like the idea of offloading this responsibility from the compositor to a specific wrapper, as it could lead to a simpler and more efficient setup.

As far as it appears to me, there's some NixOS bug that causes this.

Niri systemd integration is already about as simple and efficient as it could be though.

Indeed, this is an issue related to NixOS that has existed for years, and the solution that seems to be getting the most attention and support is uwsm. I just saw that its module has been merged two days ago. I'll test it when it lands on the unstable branch.

Niri systemd integration is already about as simple and efficient as it could be though.

I think that official support for uwsm in Niri would be beneficial for all distributions, and I see it as a clean way to separate responsibilities. Plus, by handling the session management in a separate project, Niri can benefit from the ongoing contributions made to the wrapper.

The issue persists in when niri is run through UWSM on NixOS, here's the result:

I also tried passing niri-session to UWSM but the services don't start either and the session crashes after a few seconds.
