[Pkg-utopia-maintainers] Bug#927907: flatpak directories not added to XDG_DATA_DIRS on Plasma + Wayland

[Tobias Gruetzmacher]

Package: flatpak
Version: 1.12.7-1
Followup-For: Bug #927907

Hi,

unfortunatly, this is still an issue with Plasma. As previously noted,
this should be covered by the user-environment-generator, but it seems
Plasma isn't using those by default (or their result isn't propagated?),
since it's not integrated in the systemd user session. This can be
actived by:

kwriteconfig5 --file startkderc --group General --key systemdBoot true

This makes the environment generator work.
https://invent.kde.org/plasma/plasma-workspace/-/wikis/Plasma-and-the-systemd-boot
suggests distros not enable this by default, since it breaks drkonqi :(

Until this becomes the default, maybe add a file
/etc/xdg/plasma-workspace/env/flatpak.sh with the content:

    eval `GIO_USE_VFS=local flatpak --print-updated-env`
    export XDG_DATA_DIRS

This should add the missing configuration to all new Plasma sessions.

Best regards, Tobias
