From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Alternatives to xfce power manager (lemmy.ml)

I've been using i3 for a while now, but the xfce power manager doesn't work outside the desktop environment, is there any alternative you can recommend? It doesn't matter if it is a terminal based or graphical interface program, I just need something that can suspend the computer after a certain time or lock it when the laptop is closed

I use tlp.

I also have a battery info using i3status in the status bar, and a script I named battery-check, which warns me via a dunst popup and a beep when the battery gets low:

#!/bin/sh
set -eu

bat=/sys/class/power_supply/BAT0

if [ ! -d "$bat" ]; then
    exit 1;
fi

status=$(cat "$bat/status")
energy_now=$(cat "$bat/energy_now")
energy_full=$(cat "$bat/energy_full")

battery_percent=$(( ${energy_now}00 / ${energy_full} ))

if [ "$status" != "Charging" -a "$battery_percent" -le 15 ]; then
    dunstify -t 8000 -u critical "Battery at ${battery_percent}%"
    play -q -n -c1 synth 2 sine 600
fi

I run this from my ~/.config/sway/config like so:

exec sh -c 'while true; do sleep 180; battery-check || break; done'
