A lightweight system tray application that prevents your screen from going to sleep. Perfect for presentations, watching videos, or any situation where you need your display to stay active.
This applet uses the D-Bus screensaver interface (org.freedesktop.ScreenSaver) to tell your system not to activate the screensaver or power saving mode. When activated, it maintains a screen wake lock that keeps your display on until you either deactivate it or close the application.
