* fix: six bugs found testing main on a real Pi (ledpi) - Stopping the service now runs cleanup. systemd stops ledmatrix.service with SIGTERM, whose default action ended Python before run()'s finally block, so the update worker, Vegas and the panel were never torn down. main() now turns SIGTERM into KeyboardInterrupt, the Ctrl-C path. - "Now showing" no longer turns into "unknown". display_current_state was only written on a mode change and the web UI reads it with max_age=120, so a live game or a single plugin on screen for longer read as unknown. It is republished every 30 s while unchanged. - Switching Vegas on in the web UI works when it was off at startup. The coordinator was only created at startup; the config watcher now flags it and the render thread creates it. - configure_web_sudo.sh finds reboot and poweroff in /usr/sbin. Run as the web user it could not, silently dropped their rules and still said it granted them, so the web UI's Reboot/Shutdown stopped working. - check_system_compatibility.sh reports installed packages as installed. `dpkg -l | grep -q` under pipefail failed when grep exited early. - A network failure fetching GitHub repo info logs a WARNING, not ERROR.

The dpkg-query stub read $4, but the package name is the third (last) argument. Both now pass on a Pi. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(display): cover the follower, long-render and startup cases Review follow-ups on the ledpi fixes: - The pending Vegas start is applied before the sync-follower branch too (_apply_pending_vegas_init), which skips _is_vegas_mode_active() while a follower is connected but needs the coordinator for the leader's image. - _service_pending_changes(), which runs inside Vegas iterations and long screens, republishes a stale display_current_state as well; the main loop alone could be away for a 240 s Vegas iteration. - The SIGTERM handler is installed after DisplayController() is built, so a stop during parallel plugin loading keeps the default immediate exit.

Installation Scripts
This directory contains scripts for installing and configuring the LEDMatrix system.
Scripts
one-shot-install.sh- Single-command installer; clones the repo, checks prerequisites, then runsfirst_time_install.sh. Invoked viacurl ... | bashfrom the project root README.install_service.sh- Installs, enables and starts the display service (ledmatrix.service), the web interface service (ledmatrix-web.service) and the update-verify units (systemd)install_web_service.sh- Installs only the web interface service and the update-verify units (systemd)install_wifi_monitor.sh- Installs the WiFi monitor daemon servicesetup_cache.sh- Sets up persistent cache directory with proper permissionsconfigure_web_sudo.sh- Configures passwordless sudo access for web interface actionsconfigure_wifi_permissions.sh- Grants the web interface's user (the user who runs the script, i.e. the one you installed LEDMatrix as; there is noledmatrixsystem user) the passwordlessnmcliand related WiFi permissions the web interface needsinstall_dns_fix.sh- Optional. Installsledmatrix-dns-fix.service, which addsoptions single-requestto the resolver when API calls time out (seesystemd/README.md)install_mqtt_bridge.sh- Optional. Installs the Home Assistant MQTT bridge service (seeintegrations/mqtt_bridge/README.md)
Libraries (sourced, not run):
lib_sudoers.sh- The web interface's sudo allow-list (/etc/sudoers.d/ledmatrix_web), shared byfirst_time_install.shandconfigure_web_sudo.shlib_systemd_render.sh-sed_escape_replacement, used by every script that renders a unit fromsystemd/*.servicelib_lowmem.sh- Build-job sizing and temporary swap for the C++ build on low-memory Pis (first_time_install.shStep 6)
Usage
These scripts are typically called by first_time_install.sh in the
project root (which itself is invoked by one-shot-install.sh), but
can also be run individually if needed.
Note: Most installation scripts require sudo privileges to install systemd services and configure system settings.
