Field report (Nobara, 0.19.2): entering Game Mode mid-stream left the monitor on and the stream mirroring at the desktop's resolution. Root cause: the DM-flavor takeover needs privilege to stop plasmalogin, the polkit rule is a docs-only manual step nobody installs, so every managed entry silently degraded to ATTACH — and with a physical display connected the attach path mirrors the box's own session at its own mode. Ship the privilege with the packages instead: a root helper (libexec/punktfunk/pf-dm-helper, verbs stop|restore) behind its own polkit action (io.unom.punktfunk.dm-helper, allow_any — the same mechanism Nobara's os-session-select uses, and the helper derives the DM unit from the display-manager.service symlink itself so callers never name a unit across the privilege boundary). The host tries the plain system-bus verbs first (root / operator rule still take precedence), then pkexec's the helper; the restore paths (idle restore + in-stream desktop-switch honor) use the same ladder so a takeover that needed the helper can always be undone by it. Packaged in rpm/deb/arch (Arch under /usr/lib/punktfunk with the policy's exec.path annotation rewritten; the host probes both layouts). Nix is left out deliberately: store paths can't match the probe, NixOS keeps the manual rule. Docs updated — the rule snippet stays as the scoped alternative.
