Bug#1050802: xfce4-session: please provide an xfce-portals.conf for xdg-desktop-portal
Source: xfce4-session
Severity: normal
Tags: trixie sid
User: xdg-desktop-portal@packages.debian.org
Usertags: portals.conf
xdg-desktop-portal 1.17.x introduces a new way to select which portals will
be used for which desktop environments, modelled on mimeapps.list:
- each desktop environment should provide a file like
/usr/share/xdg-desktop-portal/xfce-portals.conf
- the filename is ${DESKTOP}-portals.conf where ${DESKTOP} is the desktop
environment's entry in $XDG_CURRENT_DESKTOP (the same as the DesktopNames
from /usr/share/{x,wayland-}sessions/*.desktop), folded to lower case
- sysadmins and users can override this via files named portals.conf or
${DESKTOP}-portals.conf in various locations like /etc/xdg-desktop-portal
and ~/.config/xdg-desktop-portal
Please see portals.conf(5) or its source code
https://github.com/flatpak/xdg-desktop-portal/blob/main/doc/portals-conf.rst
for full details.
As a backwards-compatibility mechanism, x-d-p will fall back to trying
to guess the most appropriate portals from the portals' UseIn= fields,
but it will log warnings when it does that, and anyway Debian doesn't
currently ship any portal backends that are flagged as suitable for XFCE
(although I see there's an ITP open for x-d-p-xapp, #1038946). Please
add an xfce-portals.conf to tell x-d-p more explicitly what backends
XFCE is meant to be using by default.
For example, if the intention is to try to use the -xapp backend, falling
back to -gtk if -xapp isn't installed or doesn't know how to do something,
the way to write that would be:
[preferred]
default=xapp;gtk;
The desktop environment (either xfce4-session or some larger metapackage)
should probably also have a Recommends, or at least a Suggests, on whatever
portals would be most appropriate for it.
Thanks,
smcv
