cleanup-desktop.sh still described the era when Officer installed a desktop of
its own — XFCE on a TigerVNC Xvnc — so tearing the remote desktop down meant
deleting a desktop nobody else used. That stopped being true when the setup
moved to mirroring the machine's existing session with x11vnc, and the script
was left actively dangerous: it purged dbus-x11 and Brave, deleted ~/.vnc, and
reinstalled gnome-keyring, all of which the current GNOME setup depends on or
deliberately removes. Running it today broke the desktop rather than cleaning
it up.
Rewritten as the actual inverse of setup-desktop.sh:
- removes what Officer added — x11vnc, ~/.vnc, the GDM auto-login and forced
Xorg keys, the forced EDID and its kernel command line, the login-time mode
setter, the legacy officer-vnc unit, the VNC entries in .env
- keeps ubuntu-desktop, gdm3 and dbus-x11, which are the machine's own desktop
and not Officer's to delete
- still purges XFCE and TigerVNC when present, since a host set up by the older
script carries them and they are precisely what this undoes
- Brave is opt-in behind --purge-brave: setup installs it, but by teardown time
it is usually just the user's browser with their profile in it
The GRUB and GDM edits were checked against copies of the real files: stripping
the EDID parameters leaves other kernel arguments intact wherever they sit in
the line, and the GDM revert does not disturb the commented examples that ship
in custom.conf. The package matcher names each xfce-family prefix rather than
globbing '^libxf', which would have taken libxfixes, libxft and libxfont with it.

replaces the single hardcoded systemd VNC service with a dynamic
sidecar that manages per-user VNC sessions on demand. any authenticated
user can now access their own desktop, not just Super Admin.
