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

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?

[–] [email protected] 7 points 5 months 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.

cat > /usr/local/bin/check_ac.sh <<EOF
#!/bin/bash

while true; do
    if [[ "$(cat /sys/class/power_supply/AC/online)" -eq 0 ]]; then
        notify-send -t 20 -a "Power" "AC Disconnected"
    fi
		sleep 20
done
EOF

chmod +x /usr/local/bin/check_ac.sh

cat > /etc/systemd/user/ac-warning.service <<EOF
[Unit]
Description=Monitor AC State and Notify

[Service]
ExecStart=/usr/local/bin/check_ac.sh
Restart=always

[Install]

systemctl --user daemon-reload
