NixOS: blueman does not work: Unable to load plugin module NMDUNSupport, Unit blueman-mechanism.service not found #69555

tex · 2019-09-26T16:54:17Z

I did update to today's master and blueman stopped working. Any idea what to do?
I have hardware.bluetooth.enable = true in my configuration.nix.

@tex I think I'll have a PR to fix this incoming soon.

I run 19.09.git.810a568 (which includes #69434 and #70149) on my machine and I still have the same issue, blueman-mechanism.service is not found.
I added package blueman also into services.dbus.packages.

tex · 2019-10-03T09:15:07Z

Confirm, I have the same problem.

ck3d · 2019-10-03T12:15:05Z

blueman 2.1 has introduced the unit blueman-mechanism.service and is stored in ${pkgs.blueman}/lib/systemd/system . dbus is not searching in that folder.

worldofpeace · 2019-10-03T14:41:19Z

Are any of you using the nixos service?

https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/desktops/blueman.nix

ck3d · 2019-10-03T15:46:01Z

No, but thanks for your hint. Activating the service solved the issue!

tex · 2019-10-03T17:22:47Z

Confirm, it works when the service is enabled!
