Estoy usando Ubuntu 17.10 con Gnome en una computadora portátil Asus.
En la interfaz de Configuración de energía, debajo de la pestaña Energía, hay una opción en la parte inferior para configurar qué hacer en caso de que la batería se agote.
Sin embargo, cuando hago clic en el menú desplegable para establecer esa opción, solo ofrece una opción, que es "no hacer nada":
Actualmente, mi computadora portátil se agotará con una carga de batería de 0, o cerca de ella, y luego se apagará sin advertencias, sin posibilidad de cerrar programas y apagarse con gracia.
Me gustaría recibir una advertencia cuando la batería esté al 10% y, con suerte, algún tiempo para guardar y apagar programas manualmente antes de apagar la computadora. ¿Cómo logro esto?

# Enable the Watts Up Pro device.

# The Watts Up Pro contains a generic FTDI USB device without a specific
# vendor and product ID. When we probe for WUP devices, we can cause
# the user to get a perplexing "Device or resource busy" error when
# attempting to use their non-WUP device.
#
# The generic FTDI device is known to also be used on:
#
# - Sparkfun FT232 breakout board
# - Parallax Propeller

# Do we ignore the lid state
#
# Some laptops are broken. The lid state is either inverted, or stuck
# on or off. We can't do much to fix these problems, but this is a way
# for users to make the laptop panel vanish, a state that might be used
# by a couple of user-space daemons. On Linux systems, see also

# Policy for warnings and action based on battery levels

# Whether battery percentage based policy should be used. The default
# is to use the time left, change to true to use the percentage, which

# battery than letting it rest for example).
# default=true

# When UsePercentageForPolicy is true, the levels at which UPower will
