Error calling StartServiceByName for org.freedesktop.impl.portal.desktop.gnome: Timeout was reached

[vulpes2]

Note: this is not the common problem where applications that use portals take forever to start, this is about xdg-desktop-portal itself taking an unusual amount of time to start.

OS: Fedora 38 (beta)
Desktop Environment: Plasma 5.27.3
xdg-desktop-portal: 1.16.0

After upgrading my system, I noticed a lot of programs take almost forever to start, and it ended up being caused by xdg-desktop-portal not running as it should be. Later I found out xdg-desktop-portal now takes over a minute to start, which is longer than the default timeout (60s).

This can be partially mitigated by extending the TimeoutSec setting for the systemd unit , but I would still have to wait over a minute after logging in to be able to launch most of my applications. I'm not quite sure how to debug this any further, any help or information would be greatly appreciated.

Uninstalling xdg-desktop-portal-gnome fixed the timeout, now xdg-desktop-portal can start almost instantly as expected. Interestingly this package is also installed on Fedora 37's KDE spin and it's enabled by default, however it doesn't seem to be causing any issues on F37, only on F38.

This should be addressed with #985 and https://gitlab.gnome.org/GNOME/xdg-desktop-portal-gnome/-/merge_requests/78.

Still happens for me on x-d-p 1.16.0 + cherry-picked 2a21927 + x-d-p-gnome 44.1

In particular,

Failed to create settings proxy: Error calling StartServiceByName for org.freedesktop.impl.portal.desktop.gnome: Timeout was reached

still happens.
I think the reason is that #985 does not change the behavior of find_all_portal_implementations so x-d-p still times out waiting for x-d-p-gnome while creating the settings portal.

That's odd, I could reproduce the problem before (using KDE), and with the updated xdp-gnome and xdp it didn't time out anymore. What distribution are you using?

What distribution are you using?

I'm using Arch Linux with an admittedly funky setup (greetd/sway/etc.)

I have tested a bit more and found that:

1. Under dbus-broker, the issue does seem to be resolved after portal-impl: Only return found implementation if it launched #985 and the settings portal does try to start x-d-p-gnome but it fails immediately w/o hitting a timeout: Failed to ReadAll() from Settings implementation: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Could not activate remote peer: startup job failed. and it falls back to the x-d-p-gtk as it should.

2. Under dbus-daemon, even after portal-impl: Only return found implementation if it launched #985 and removing org.freedesktop.impl.portal.Settings from gnome.portal, x-d-p seems to hit the the timeout when creating the dummy proxy:
