bassidus/lgpowercontrol v2.7 on GitHub

What's new

Wake-on-LAN on Fedora: ether-wake defaults to eth0; the interface that routes to the TV is now looked up automatically.
HDMI_INPUT at boot: setting the input is retried while the TV is still booting after Wake-on-LAN (power mode).
Updating from older versions: config keys missing from a preserved older lgpowercontrol.conf now fall back to their defaults instead of failing the services.
update.sh aborts early with a clear message when LGPowerControl is not installed.
The notify service exits cleanly when "Turn off screen" is disabled in Plasma, instead of warning about a TV-off that never happens.

Cleaner suspend/resume logging: the DRM monitor no longer sends a doomed duplicate TV-off during the suspend window, and a successful wake after retries is now logged.
lgpowercontrol prints a usage line when called with a missing or unknown argument.
The installer runs pacman non-interactively, like apt and dnf.
Clearer mode documentation in lgpowercontrol.conf, including a note that some models (e.g. OLED42C35LA) drop into a deeper standby ~10 minutes after screen-off; also added to README Limitations.

sudo /opt/lgpowercontrol/update.sh

Settings and TV pairing survive the update.
