Alternatives to xfce power manager

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:

<span style="color:#323232;">#!/bin/sh
</span><span style="color:#323232;">set -eu
</span><span style="color:#323232;">
</span><span style="color:#323232;">bat=/sys/class/power_supply/BAT0
</span><span style="color:#323232;">
</span><span style="color:#323232;">if [ ! -d "$bat" ]; then
</span><span style="color:#323232;">    exit 1;
</span><span style="color:#323232;">fi
</span><span style="color:#323232;">
</span><span style="color:#323232;">status=$(cat "$bat/status")
</span><span style="color:#323232;">energy_now=$(cat "$bat/energy_now")
</span><span style="color:#323232;">energy_full=$(cat "$bat/energy_full")
</span><span style="color:#323232;">
</span><span style="color:#323232;">battery_percent=$(( ${energy_now}00 / ${energy_full} ))
</span><span style="color:#323232;">
</span><span style="color:#323232;">if [ "$status" != "Charging" -a "$battery_percent" -le 15 ]; then
</span><span style="color:#323232;">    dunstify -t 8000 -u critical "Battery at ${battery_percent}%"
</span><span style="color:#323232;">    play -q -n -c1 synth 2 sine 600
</span><span style="color:#323232;">fi
</span>

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

<span style="color:#323232;">exec sh -c 'while true; do sleep 180; battery-check || break; done'
</span>

TLP

also

acpitool

Sometimes I forget to connect the charger to the laptop, and it discharges without realizing it. When I used xfce power manager, it warned me when the charger was disconnected, can tlp or acpitool send those types of notifications?

What are the differences between tlp and acpitool?

dogsnest, 26 days ago

In a nutshell TLP’s default settings are optimized for battery life upon installation, allowing you to further tweak/adjust to your needs. Whereas acpitool analyzes, but doesn’t optimize without your input.

As for notifications, I don’t believe either package provides them, especially since they’re both cli tools (TLP has a gui, TLPUI)

As for notifications, a bash script similar to this would work:

ac_adapter=$(acpi -a | cut -d’ ’ -f3 | cut -d- -f1) if [ “$ac_adapter” = “on” ]; then notify-send “AC Adapter” “The AC Adapter is on.” else notify-send “AC Adapter” “The AC Adapter is off.” fi

Also adding auto-cpufreq, ryzenadj, tuned.

But this depends on your CPU used.

TLP is good, tuned may be better?

TLP has a common USB lost issue, that is mitigated by disabling USB-autosuspend in the config. TLP config is found here

And if you need a tool for warning about AC disconnect, you can use a systemd service.

<span style="color:#323232;">cat > /usr/local/bin/check_ac.sh <<EOF
</span><span style="color:#323232;">#!/bin/bash
</span><span style="color:#323232;">
</span><span style="color:#323232;">while true; do
</span><span style="color:#323232;">    if [[ "$(cat /sys/class/power_supply/AC/online)" -eq 0 ]]; then
</span><span style="color:#323232;">        notify-send -t 20 -a "Power" "AC Disconnected"
</span><span style="color:#323232;">    fi
</span><span style="color:#323232;">		sleep 20
</span><span style="color:#323232;">done
</span><span style="color:#323232;">EOF
</span>

<span style="color:#323232;">chmod +x /usr/local/bin/check_ac.sh
</span>
