Bare Openbox rendered only a blank slate root — usable but not the
desktop wanted. Make the X11/NVENC capture path render a full GNOME
session by default, with Openbox available via HEADLESS_DESKTOP=openbox
for minimal/low-power hosts.
- files/headless-desktop-gnome.service: full Ubuntu GNOME session forced
onto the X11 path (XDG_SESSION_TYPE=x11, no dbus-run-session so it
shares the systemd user bus). Renamed the Openbox unit to
headless-desktop-openbox.service.
- lib/headless.sh: HEADLESS_DESKTOP (default gnome) selects the unit
template + the packages to install (gnome-session/gnome-shell vs
openbox/xsetroot).
- install.sh: step message + usage document HEADLESS_DESKTOP.
- status.sh: the :0 desktop check now reports which desktop is running
(reads _NET_WM_NAME off the supporting-wm-check window, e.g.
"GNOME Shell").
- docs: TROUBLESHOOTING §13 + FOLLOWUPS P3 updated for the GNOME default
and the openbox toggle.
