This bundles every fix we made debugging the first real install plus a
comprehensive troubleshooting reference. Working tree is now PII-safe for
public distribution: hostname-based default mode is driven by a HEADLESS_HOSTS
env var instead of a hardcoded literal; docs use placeholders for hostnames
and LAN IPs.
Self-healing headless management
- bin/sunshine-prestart.sh (new): runs as systemd ExecStartPre. Resolves the
Hyprland instance signature from XDG_RUNTIME_DIR/hypr when systemd-user env
didn't propagate it. Reduces to exactly one headless output by keeping the
lowest-numbered HEADLESS-N and removing the rest. Rewrites the managed
sunshine.conf's output_name line to match the surviving name — Hyprland's
HEADLESS-N counter is monotonic and ignores the optional name argument to
'output create headless', so without active sync output_name drifts off
HEADLESS-1 after the first restart cycle.
- bin/sunshine-stream-do.sh: dropped the hardcoded MON=HEADLESS-1. Now
discovers whatever HEADLESS-* exists via jq. Resize and workspace migration
target the actual output.
- bin/sunshine-stream-undo.sh: reads the headless name from a state file the
do-script wrote, with discovery fallback. Stops removing the output between
sessions — the create/destroy race caused fatal startup encoder errors on
the next Sunshine restart.
- files/headless-prestart.conf, files/sunshine.service: ExecStartPre now
points at the new prestart script.
- lib/headless.sh: install_headless_hooks now installs all three scripts.
New install_headless_prestart_dropin resolves the actual systemd unit name
(sunshine.service vs app-dev.lizardbyte.app.Sunshine.service) and lands the
drop-in under <unit>.service.d/.
Firewall detection
- lib/firewall.sh: _ufw_active now uses 'systemctl is-active ufw.service'
instead of 'ufw status'. The latter requires root to read /etc/ufw state,
so the unprivileged probe returned false and we silently skipped opening
Sunshine's ports on hosts where ufw was actively dropping packets.
Service unit fallbacks
- lib/service.sh: ensure_sunshine_unit_present looks for sunshine.service in
every systemd-user path first; falls back to the reverse-DNS AUR-source
unit name; last resort drops a repo-provided fallback unit. systemctl
reset-failed before each restart so a previous start-limit-hit doesn't
immediately reject the new attempt.
Preflight
- lib/preflight.sh: new preflight_headless step that, only when STREAM_MODE
is headless, surfaces missing hyprctl / jq / Hyprland reachability before
install proceeds.
Public-safe defaults
- install.sh: streaming-mode default is now driven by HEADLESS_HOSTS env var
(comma-separated, case-insensitive). Unset by default — every host gets
mirror mode unless its hostname is listed or --headless is passed
explicitly. Past versions hardcoded a specific hostname.
- README.md: replaced JARVIS-specific examples with HEADLESS_HOSTS prose.
Docs
- docs/TROUBLESHOOTING.md (new): comprehensive failure-mode reference. Every
issue hit during the first end-to-end install, in order, with symptom →
cause → fix → permanent prevention. Plus a "Custom keybinding to escape
Moonlight" section and an outstanding-followups punch list (1Password
black-rectangle workarounds, hypridle inhibit during stream, busiest-
workspace auto-switch, jarvis.lan DNS, 1Password SSH agent timeouts).
Headless mode (new) — for KVM-attached hosts streaming to disconnected clients
- --headless / --mirror flags; default headless on hostname JARVIS, mirror elsewhere
- New lib/headless.sh installs prep-cmd hooks to ~/.local/share/omarchy-moonlight/bin
- bin/sunshine-stream-do.sh creates/resizes a Hyprland HEADLESS-1 output to the
connecting client's resolution and migrates the active workspace onto it
- bin/sunshine-stream-undo.sh tears down the headless output on disconnect and
returns the workspace to a non-headless monitor when one is available
- lib/config.sh writes capture=wlr, output_name=HEADLESS-1, and the JSON
global_prep_cmd entry referencing the installed hook paths
- lib/preflight.sh adds a preflight_headless step that checks hyprctl, jq, and
a running Hyprland session (warn-only, install can proceed)
- lib/verify.sh adds checks for the hook scripts and the wlr/global_prep_cmd
config lines
Mac client
- client/install-macos.sh: Darwin guard, Homebrew presence check, brew cask
install of Moonlight, idempotent
- client/README.md: per-platform install (macOS / Android / iOS / Apple TV /
Linux + Steam Deck) and the five-step first-pair walkthrough
Other
- jq added to the helper install set in lib/packages.sh (hooks parse Hyprland
JSON output)
- README.md rewritten to cover both modes, the new flags, the tuned defaults
per mode + per vendor, the headless internals, and the client pointer
