Description benjgentil 2023-09-28 11:58:56 UTC 
When I try to open/save a file from various applications (vivaldi, chromium, slack...) nothing happens

Reproducible: Always

Steps to Reproduce:
1.Install fedora 38
2.Install sway, vivaldi, chromium from packages or slack from flatpak
3.Try to open a file chooser dialog
Actual Results:  
Nothing happens

Expected Results:  
A file chooser dialog should be opened

From what I understand it should be handled by a `org.freedesktop.impl.portal.FileChooser` interface provided by gtk.

If I set `UseIn` to `gnome;sway` instead of `gnome` in /usr/share/xdg-desktop-portal/portals/gtk.portal, everything works as expected.
Comment 1 Fabio Alessandro Locati 2023-09-28 12:30:38 UTC 
When you say "install sway", what exactly do you mean? Which package are you installing?

Also, please, provide the output of `rpm -qa|grep sway`.

The file /usr/share/xdg-desktop-portal/portals/gtk.portal is owned by xdg-desktop-portal-gtk, so if the correct solution is the one you are suggesting, a bug against xdg-desktop-portal-gtk should be opened.

Thanks
Comment 2 benjgentil 2023-09-28 13:19:57 UTC 
Thank you for the fast response!

I installed sway quite a while ago so to be honest I don't remember the exact packages I installed, I just know that I have `sudo dnf install sway` in my shell history and my current packages are:
```
swaylock-1.7.2-1.fc38.x86_64
swayidle-1.8.0-2.fc38.x86_64
swaybg-1.2.0-2.fc38.x86_64
sway-wallpapers-1.8.1-1.fc38.noarch
sway-1.8.1-1.fc38.x86_64
sway-config-upstream-1.8.1-1.fc38.noarch
sway-systemd-0.4.0-1.fc38.noarch
```

I filed the bug against sway because the issue is sway-specific and I don't know how those dialogs should be displayed when using sway, maybe xdg-desktop-portal shouldn't be used with sway, I wish I could select multiple components in the bug tracker as it is more of an interface issue between 2 components rather than a bug on a single one.
Comment 3 Aleksei Bavshin 2023-09-29 02:41:35 UTC 
Lovely. And 100% reproducible - just take up-to-date F38 Sway spin installation and add `xdg-desktop-portal-gnome`.

`xdg-desktop-portal` picks `xdg-desktop-portal-gnome` for all the portals provided by the backend. Completely ignoring the fact that GNOME portal backend is running in a degraded Settings-only mode and refuses to serve any other impls.
It should be fixed with `xdg-desktop-portal-1.18.0` and new `portals.conf` configuration, but we don't have that in Fedora 38 :(

> If I set `UseIn` to `gnome;sway` instead of `gnome` in /usr/share/xdg-desktop-portal/portals/gtk.portal, everything works as expected.

Yep. That seems to work, because it goes straight to the -gtk backend instead of checking all available implementations in alphabetic order.
Doesn't really help on Silverblue with layered Sway (/usr is readonly), but `Environment=XDG_DESKTOP_PORTAL_DIR=%h/.config/xdg-desktop-portal/portals` in the systemd unit override may solve that.

Anyways, the bug goes to the rightful owner at `xdg-desktop-portal`.

Comment 4 sorje 2023-11-28 01:10:51 UTC 
after upgrading to fedora 39 i ran into the same bug, i am using Enlightenment.

```
enlightenment-data-0.25.4-3.fc39.noarch
enlightenment-0.25.4-3.fc39.x86_64
```

ctrl+o in brave-browser / firefox does not work.

workaround with adding enlightenment to UseIn in file /usr/share/xdg-desktop-portal/portals/gtk.portal does not seem to work.

I fixed by creating /usr/libexec/xdg-desktop-portal as personal application launcher and adding it to startup applications, that way it's started with enlightenment environment.

i am unable to remove xdg-desktop-portal-gnome as it's used by gnome-shell which protected.

```
Problem: The operation would result in removing the following protected packages: gnome-shell
```

thanks for helping out.
Comment 5 jhmj 2023-12-17 16:03:00 UTC 
for xdg-desktop-portal-gtk (amongst others) to show the file picker systemd needs to have a (default) DISPLAY env variable in it's own systemd environment

this default behaviour no longer exists?!


fix therefor:
make sure DISPLAY=:0 in the (sway) user environment
to check: env | grep DISPLAY

then import this in the --user environment of systemd

systemctl --user import-environment DISPLAY

Comment 7 Kamil Páral 2024-09-12 07:14:50 UTC 
Based on this discussion:
https://discussion.fedoraproject.org/t/131018

the problem is that people affected don't have sway-systemd package installed, perhaps because they disabled weak deps support. Please check.

It could be argued that this could be a hard dependency (in that case feel free to report it against sway-config-fedora and discuss) or that it should be explicitly listed in the "Sway Desktop" dnf group (in that case file a ticket against fedora-comps [1]).
