Spacenav module does not work in Blender

[TheSirC]

Describe the bug

With the spacenavd module active, the 3D mouse is not working.

Steps To Reproduce

Steps to reproduce the behavior:

1. Set hardware.spacenavd.enable = true
2. Open Blender
3. The 3D Mouse is not working

Expected behavior

With the module is active, the mouse should be detected and working in Blender

Additional context

If you start the binary spacenavd with sudo seems to be enough for Blender to be enough for it to work.

When the blender binary detects the mouse the first line is
sh: line 1: lsusb : command not found weirdly

I also tried hardware.spacenavd.enable = true and it does not work, no matter in which application.
Running sudo spacenavd solves the problem, but I actually expect the mouse to work the moment i plug it in.

@Sohalt could you help?

It looks like spacenavd is supposed to run on a system level, instead of a user unit like @Sohalt outlined?

nixpkgs/nixos/modules/services/hardware/spacenavd.nix

Line 16 in ee176b5

systemd.user.services.spacenavd = {

see https://github.com/FreeSpacenav/spacenavd#running-spacenavd

Spacenavd is designed to run during startup as a system daemon.

and FreeSpacenav/spacenavd#88 (comment)

spacenavd is a daemon, which is supposed to run as root.
spacenavd being a daemon, is started by init before X has even started.

[Sohalt]

Ah, sorry. It used to work as a user service, until @gebner removed the patch in 3a4f71d

I thought you fixed the patch in #118617?

Maybe it needs an update

[Sohalt]

Ah sorry. I didn't look closely enough. 🙈
I'll update all the spacenavd related packages.

[Sohalt]

Sorry, I didn't get around to finishing this yet. Here's my work in progress: #263120

[deftdawg]

Trying to get SpaceMouse going for my Podman Wine SketchUp container build, need to get the mouse working on my NixOS host first to pass /var/run/spnav.sock in as a volume.

Was about to file an issue about spacenavd needing an update from 0.8 to 1.2, but looks like @Sohalt is working on it, so I'll just hang out here... 🍻

[Sohalt]

#263120 works with Blender 3.5.1. You can either pull in the changes from there or wait until it's merged.
