Description Fina Wilke 2023-09-16 13:16:32 UTC

xdg-desktop-portal recommends the use of a portals.conf file that is to be shipped by distributions.

https://github.com/flatpak/xdg-desktop-portal/blob/main/doc/portals-conf.rst

Since the update to 1.17.2 the lack of configuration apparently causes the org.freedesktop.portal.Settings portal to be missing from dbus. Most notably this means that org.freedesktop.appearance.color-scheme isn't available which breaks the dark style.

This also causes 

> Choosing gnome.portal for org.freedesktop.impl.portal.Lockdown via the deprecated UseIn key
> The preferred method to match portal implementations to desktop environments is to use the portals.conf(5) configuration file

to be logged to the user journal.

A solution to this issue would be to ship a DESKTOP-portals.conf file  with the appropriate portal implementations. 

Reproducible: Always




Workaround:

Create a /etc/xdg-desktop-portal/portals.conf that contains:

[preferred]
org.freedesktop.impl.portal.Settings=gnome

This should be fixed with https://src.fedoraproject.org/rpms/gnome-session/pull-request/8 that adds the GNOME portal config file to the gnome-session package.
