# Workaround (SteamOS 0.3.0, build 20260922): the Steam session's portal dir
# /usr/share/xdg-desktop-portal/gamescope-portals has backends but no
# gamescope-portals.conf, so no backend is selected and there is no OpenURI
# (links don't open). We point it at our own dir: Valve's .portal files + a
# config. Remove once SteamOS ships the .conf.
