What version of xdg-desktop-portal-gnome do you have?

[luiswoo]

xdg-desktop-portal-gnome-46.0-1.fc40.x86_64

[luiswoo]

Maybe it had something to do with the fact that any ‘gnome software center’ activity was blocked. But easyeffects was updated via ‘flatpak update’, and reinstalled at least once.

[violetmage]

It sounds like a bug in xdg-desktop-portal-gnome

I'll do some more research later today, to try to find some specific troubleshooting steps.

[violetmage]

Sorry for the delay, was AFK over the weekend.

Just to be sure, are you using GNOME as your DE?

Either way, you can try the Door Knocker flatpak as a first step.

Alternatively, check the output of systemctl --user status xdg-desktop-portal-gnome xdg-desktop-portal

[luiswoo]

XFCE is mainly used.

If you are using XFCE, you should be using xdg-desktop-portal-gtk instead of xdg-desktop-portal-gnome

More info here: bbs.archlinux.org

[luiswoo]

Package xdg-desktop-portal-gtk-1.15.1-5.fc40.x86_64 is already installed

screenshot systemctl --user --type=service: https://imgbox.com/BvgZoQsj

[violetmage]

That's good, but the logs from your earlier post show that xdg-desktop-portal-gnome is what's being used. You might have to uninstall it.

[luiswoo]

I'll update my OS, install easyeffects from the Flatpak, and check in Gnome, I'll report back.

[luiswoo]

After upgrading my system, in Gnome the problems disappeared. In XFCE everything is still the same.
I don't quite understand why I should remove ‘xdg-desktop-portal-gnome’, if on request ‘systemctl --user status xdg-desktop-portal-gtk xdg-desktop-portal’ both services are active (in XFCE) and everything is fine. But on request ‘systemctl --user status xdg-desktop-portal-gnome xdg-desktop-portal’ - the answer is that desktop-portal-gnome is not active (in XFCE). What is the point of removing it?

[violetmage]

The xdg-desktop-portal-gnome will only work correctly with the full GNOME DE running, whereas xdg-desktop-portal-gtk only depends on a few sub-systems. XFCE includes these sub-systems, so it will work with the gtk portals.

If you wanted all portals to work in XFCE, the easiest way to fix the problem is to remove xdg-desktop-portal-gnome. However, removing it would of course cause GNOME to work incorrectly.

Since you have the full GNOME installed, you probably shouldn't remove xdg-desktop-portal-gnome. The problem is that I don't know of a simple way to make portals work in XFCE without also affecting GNOME.

[luiswoo]

I don't understand, for easyeffects to work correctly in XFCE it needs xdg-desktop-portal-gnome (service is not active) or xdg-desktop-portal-gtk ( service is active)?

[violetmage]

The way portals work as that there is the main xdg-desktop-portal service that apps talk to, then a "backend" service that the main service dispatches requests to, like xdg-desktop-portal-gtk or xdg-desktop-portal-gnome.

You only need a single "backend" for things to work.

[violetmage]

I've just done some more research and found the documentation for the xdg-desktop-portal service here: flatpak.github.io

In there they describe how to control the behaviour of the xdg-desktop-portal service.

So you can try this to see if it helps on XFCE:

Create the file: ~/.config/xdg-desktop-portal/xfce-portals.conf

And paste in it the following:

[preferred]
# Use xdg-desktop-portal-gtk for every portal interface
default=gtk

You would need to log out and log in again for the changes to take effect.

[luiswoo]

When adding xfce-portals.conf to ~/.config (it didn't work in other paths), a message appeared:

$ flatpak run com.github.wwmm.easyeffects.

** (process:8863): WARNING **: 02:20:45.282: Error writing credentials to socket: There was an error sending a message: Channel failure.
(the behavior remained the same, only no errors were displayed)

Instead of the usual:

$ flatpak run com.github.wwmm.easyeffects

(easyeffects:2): Gtk-WARNING **: 02:23:31.901: No IM module matching GTK_IM_MODULE=xim found

(easyeffects:2): easyeffects-WARNING **: 02:26:38.350: pipe_manager.cpp:1481 Remote error res: No such file or directory

[violetmage]

What if you change the configuration to be like this:

[preferred]
# Use xdg-desktop-portal-gnome for every portal interface...
default=gnome
# ... except for the Background interface
org.freedesktop.impl.portal.Background=gtk

If this doesn't work, then I think the only options are to either
a. Just use GNOME
b. Uninstall GNOME and the GNOME desktop portals, to try to make XFCE work
c. Use the native packaged easyeffects

[luiswoo]

Is this a setting for the ~/.config/portals.conf file? (~/config/xdg-desktop-desktop-portal/portals.conf was also tried) If so, it doesn't lead to anything.

[violetmage]

I don't know what else to say at this point. You could try asking on the fedora forums for more help.

Sorry I couldn't help find the problem.

[luiswoo]

As I understood from the discussion #1363 xdg-desktop-portal-gnome is REQUIRED for easyeffects to work in XFCE, but it is not loaded at system boot “Dependency failed for xdg-desktop-portal-gnome.service - Portal service” - I can't start it manually: “Failed to start xdg-desktop-portal-gnome.service: Unit xdg-desktop-portal-gnome.service not found.”

[wwmm]

Unit xdg-desktop-portal-gnome.service not found

Strange. At least on Arch Linux this file is provided by the xdg-desktop-portal-gnome package. Maybe something went wrong when the Fedora package was done.

But in this case it should be broken in gnome too... Hum... Really weird...

[luiswoo]

Maybe the developers banned it from running in DE other than Gnome, because of problems like here: https://gitlab.gnome.org/GNOME/xdg-desktop-portal-gnome/-/issues/74

It does not seem it was banned https://gitlab.gnome.org/GNOME/xdg-desktop-portal-gnome/-/merge_requests/95. It just does not keep waiting for a reply from Mutter. Something that will never happen outside of gnome. The question is if exposing just the settings backend is enough.

Anyway I do not understand why xfce doesn't work with just the gtk backend.

[luiswoo]

Installed from the official Fedora repository (version 7.1.6) and uninstalled the flattpack version and it worked.

The native package does not use the background permission infrastructure. This permission management is a flatpak thing.
