I installed F39 XFCE on a new machine and noticed that links do not work. After a significant amount of digging (and some help from the forum https://discussion.fedoraproject.org/t/cant-open-links-from-flatpak-applications/95614), we determined that the issue is that the XFCE spin does not have a configuration for `xdg-desktop-portal`. It looks like this issue has been fixed upstream with two fixes, both of which are likely required to be brought downstream. 1. Adding a portals.conf for XFCE https://gitlab.xfce.org/xfce/xfce4-session/-/blob/xfce-4.18/xfce4-session/xfce-portals.conf?ref_type=heads 2. Ensuring that XDG_* variables are populated upon login https://gitlab.xfce.org/xfce/xfce4-session/-/commit/0fe26b4d0eab7207c5349af340eb9e8cb833e29c It seems this originates from the fact that x-d-p removed fallbacks for link handling, and now desktop environments are required to provide configurations for it. Unfortunately, even if you do add a `xfce-portals.conf`, right now the XDG_CURRENT_DESKTOP variable is not populated automatically, hence the need for the second fix ``` $ systemctl --user show-environment HOME=/home/nick LANG=en_US.UTF-8 LOGNAME=nick PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin SHELL=/usr/bin/zsh USER=nick XDG_DATA_DIRS=/home/nick/.local/share/flatpak/exports/share:/var/lib/flatpak/exports/share:/usr/local/share/:/u> XDG_RUNTIME_DIR=/run/user/1000 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus DISPLAY=:0 XAUTHLOCALHOSTNAME= XAUTHORITY=/run/lightdm/nick/xauthority ``` Reproducible: Always Steps to Reproduce: 1. Open a flatpak app that has clickable links, such as Signal 2. Click the link 3. Observe nothing happens Actual Results: The link does not open in my browser Expected Results: The link should open in my browser
This has been resolved by restoring the fallback to xdg-desktop-portal-gtk: https://bodhi.fedoraproject.org/updates/FEDORA-2023-eec70fd3ad Those two commits would still be nice to have, but I think it can wait for an upstream release now. The only practical change would be using xdg-desktop-portal-xapp for the Wallpaper and Screenshot portals, and that's not installed by default anyway.
