Я использую Ubuntu 17.10 с Gnome на ноутбуке Asus.
В интерфейсе «Настройки электропитания» на вкладке «Питание» внизу есть опция для настройки действий в случае критического разряда батареи.
Однако, когда я нажимаю на раскрывающийся список, чтобы установить эту опцию, он предлагает только одну опцию, которая "ничего не делать":
В настоящее время мой ноутбук разряжается до нуля от батареи или близко к нему, а затем выключается без предупреждений, без возможности закрытия программ и корректного выключения.
Я хотел бы получить предупреждение, когда уровень заряда батареи составляет 10%, и, надеюсь, некоторое время вручную сохранить и закрыть программы, прежде чем выключать компьютер. Как мне этого добиться?
Редактировать: вот содержимое моего /etc/UPower/UPower.confфайла:

# 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
# logind.conf(5).

# 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
# should work around broken firmwares. It is also more reliable than
# the time left (frantically saving all your files is going to use more
# battery than letting it rest for example).
# default=true
UsePercentageForPolicy=true
# When UsePercentageForPolicy is true, the levels at which UPower will
# consider the battery low, critical, or take action for the critical
# battery level.
#
# This will also be used for batteries which don't have time information
# such as that of peripherals.
#
# If any value is invalid, or not in descending order, the defaults
# will be used.

# When UsePercentageForPolicy is false, the time remaining at which UPower
