[SOLVED] xdg-desktop-portal-wlr fails to start

Hi, I'm using Hyprland on wayland (wlroots), and everything worked flawlessly up until my last reboot. I'm not sure why, but it seems that `xdg-desktop-portal` and `xdg-desktop-portal-wlr` are suddenly failing to start.

This is the output of

systemctl --user status xdg-desktop-portal.service

○ xdg-desktop-portal.service - Portal service
     Loaded: loaded (/usr/lib/systemd/user/xdg-desktop-portal.service; static)
     Active: inactive (dead)

Oct 23 11:13:06 pc systemd[852]: Started Portal service.

And this is output of

systemctl --user status xdg-desktop-portal-wlr.service

Oct 23 11:16:03 pc systemd[852]: Failed to start Portal service (wlroots implementation).

When I try to start the portal manually, there's this error message (from `/usr/lib/xdg-desktop-portal-wlr`):

2022/10/23 11:27:05 [ERROR] - dbus: failed to acquire service name: File exists
'impl->enter_count > 0' failed at ../pipewire/spa/plugins/support/loop.c:346 loop_leave()

And running `/usr/lib/xdg-desktop-portal` manually just results in:

(/usr/lib/xdg-desktop-portal:14065): xdg-desktop-portal-WARNING **: 11:32:48.391: No skeleton to export

This might be caused by something new that I've installed or something similar, but I've no idea what exactly, I've been making a lot of changes before the reboot this happened after, as I was just setting up the machine, from the error message, it seems like it has something to do with pipewire? However I'm not sure what is the issue exactly and even how to debug it. Any suggestions?

Re: [SOLVED] xdg-desktop-portal-wlr fails to start

Ok, so quick update, there really seems to be something wrong with pipewire, but I'm not sure whether it's an actual pipewire issue, or whether it's because the portals aren't running.

While the sound seems to be working fine, the issue occurs with anything pulseaudio related (using `pipewire-pulse`). Running `pactl info` just results in

Connection failure: Timeout

However the service does seem to be running

systemctl --user status pipewire-pulse.service

Re: [SOLVED] xdg-desktop-portal-wlr fails to start

Marking as solved, this was actually not an issue with the portals, that was just me being stupid. The issue with portals was that hyprland wiki suggested making a script that restarts these portals, which killed the original running proccesses of these, and started them directly without using systemd. They then failed to restart because they were already running.

The actual issue that I had was just with `pipewire-pulse`, and this happened because I was trying to implement a fix for discord notification suggested by arch wiki, by adding `/etc/pipewire/pipewire-pulse.conf` file with certain configuration. The issue was that I used a wrong closing bracket (`}` instead of `]`), which clearly caused some issues, although it is surprising that this wasn't reported a bit more clearly in the `pipewire-pulse` systemd log. But anyway, basically this was just me being an idiot, marking fixed.
