It blanks the screen after a configurable idle timeout, suspends on battery after extended idle, and restores brightness on any input activity : no D-Bus, no logind, no powerdevil, no device polling. It is a shell script wrapping <code>swayidle</code>, which speaks the <code>org_kde_kwin_idle</code> Wayland protocol directly to KWin.</p> <p>This is a rewrite. The original was a Python daemon that polled input devices directly. That approach had fundamental problems on FreeBSD and was replaced entirely with a sh wrapper around <code>swayidle</code>.</p>
