# punktfunk host configuration (~/.config/punktfunk/host.env) — consumed by punktfunk-host.service. # # The compositor + input backend are AUTO-DETECTED per connect from the live session (the host # probes which compositor is actually running and retargets WAYLAND_DISPLAY/XDG_CURRENT_DESKTOP/ # DBUS at it), so a box that flips between Steam Gaming Mode and a KDE/GNOME desktop is followed # automatically. The blocks below are OPTIONAL OVERRIDES — uncomment one only to force a backend # (this also skips the per-connect env retargeting). The anchors XDG_RUNTIME_DIR + DBUS stay. # Session / compositor environment (headless KWin example).
