+# gnome-shell-screenpad
+
+A simple brightness slider for ASUS Zenbook Duo laptops' second "ScreenPad Plus" screens, that appears in the "Quick Settings" dropdown.
+
+Requires the [asus-wmi-screenpad](https://github.com/Plippo/asus-wmi-screenpad) or [asus-wmi-screenpad-module](https://github.com/MatthewCash/asus-wmi-screenpad-module) kernel module, which provides the `/sys/class/leds/asus::screenpad/brightness` file.
+
+This _will_ allow you to quickly turn the second screen back on if it doesn't wake from sleep.
