I wouldn't call it an easy solution, but with the info in the answers here you can probably get what you want: How can I get an alert when my battery is about to die in Linux Mint?

Yes, I read that when I was looking for an audible solution and agree, it is not easy, for me anyway.

Here is a similar script with instructions (includes both a sound and bubble notification) geared towards your system. Create the file batteryalert.sh in your home directory with the following content:

#!/bin/bash

lockfile=/tmp/.batteryalert.$USER.lockfile
if ( set -o noclobber; echo "locked" > "$lockfile") 2> /dev/null; then
  	trap 'rm -f "$lockfile"; exit $?' INT TERM EXIT
  	echo "batteryalertDEBUG: Locking succeeded" >&2

	while true
	do
		sleep 15s
		P=$(upower -d | grep -A20 BAT1 | grep percentage | awk '{print $2 }' | sed -e 's/%//g')
		if [ $P -lt 10 ];
		then
			notify-send -i dialog-warning "Battery Low Warning" "The battery is below 10% charge!"
			mplayer /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga > /dev/null 2>&1
		fi
	done
	
else
  	echo "batteryalertDEBUG: Lock failed, check for existing process and/or lock file and delete - exiting." >&2
  	exit 1
fi			

exit 0

...and make the file executable:

chmod +x ~/batteryalert.sh

Note: I'm using mplayer to play the sound. Either make sure that mplayer is installed or change the command to use another program to play the sound.

Then create the file ~/.config/autostart/batteryalert.desktop with the following content:

[Desktop Entry]
Encoding=UTF-8
Version=0.9.4
Type=Application
Name=batteryalert
Comment=batteryalert
Exec=/home/makem/batteryalert.sh
OnlyShowIn=XFCE;
StartupNotify=false
Terminal=false
Hidden=false

The next time you log in, this script will start and you will get an audible and visual alert every 15 seconds when the battery drops below 10% charge.

Thank you ToZ, gonna use it myself!

@ToZ

That appears to be a script I saw when looking around for something.

Thank you, I can do that with your instructions.

lol. Make sure you change the "BAT1" in the script to be your actual battery device name (mine is BAT0).

Should read:

chmod +x ~/batteryalert.sh

Right?

Where do I find battery name?

Ah, it is battery_BAT1 big_smile

You are most welcome.

You have:

P=$(upower -d | grep -A20 BAT1 | grep percentage | awk '{print $2 }' | se$

Is the -A20 part of the battery name or a command? I think command. (will read the upower man)

My battery name includes a 'battery_' prefix to the BAT1

ToZ · 2019-12-26 15:24:05

The "-A 20" means return 20 lines after the match to BAT1 (you will only have one of this string in that output). Included in those 20 lines is the percentage line so I clumsily pull that out using greps, awks and seds. The prefix is not important here.

I have VLC media player installed and also installed mplayer to align with the script.

I get the popup warning along with what appears to be two sounds. One a very quiet tapping and the other like a very quiet squeak. I think that sound is being played by VLC because I can choose that player to play the file alarm-clock-elapsed.oga.

If I choose from the command line mplayer alarm-clock-elapsed.oga I get a file not found error.

As far as I am aware the command is mplayer foo.mp3 so I am surprised it does not play the alarm. Can you enlighten me please?

Better still, how to edit the script to use vlc?

Substitute "mplayer" for "cvlc" in the script.

Sorry, I think you refer to a post in which I substituted cvlc for mplayer because the sound was very quiet and I normally use vlc media player.

I want to use cvlc.

I found that the usual system popup triggered at !0% and stopped me doing anything except answer it. I thought the script was a replacement for that and therefore assumed the script did not work. However, during the changes I made I found that the script sound triggered below and after the system popup. So, now I know the script works but need to change it to a value greater than 10% I think. In that way the script will audibly warn me and if I fail to action that the system popup will save any data loss if I fail to heed that too.

As it currently stands the system will save data and shut down before the script works I think.

Replacing mplayer with cvlc works and the sound level is that set by the system.

I left the script setting at 10% and set the system to 8%.

However, I think using cvlc stops the script which hangs after it only triggers once.

When I use cvlc from the command line I get:

makem@ssdTOSH:~$ cvlc /home/makem/Desktop/fart.wav
VLC media player 3.0.8 Vetinari (revision 3.0.8-0-gf350b6b5a7)
[0000559c5c0698c0] dummy interface: using the dummy interface module...

The terminal hangs at that point having played the sound. This must also be happening in the script.

Using xubuntu (ubuntu 18.04.3 LTS) with XFCE desktop and having uninstalled the xfce4-battery-plugin, leaving only the xfce4-power-manager installed.

For me this edited script (mplayer replaced by aplay) works correctly with the system critical power setting at 8%:

#!/bin/bash

lockfile=/tmp/.batteryalert.$USER.lockfile
if ( set -o noclobber; echo "locked" > "$lockfile") 2> /dev/null; then
        trap 'rm -f "$lockfile"; exit $?' INT TERM EXIT
        echo "batteryalertDEBUG: Locking succeeded" >&2

        while true
        do
                sleep 15s
                P=$(upower -d | grep -A20 battery_BAT1 | grep percentage | awk '{print $2 }' | sed -e 's/%//g')
                if [ $P -lt 10 ];
                then
                        notify-send -i dialog-warning "Battery Low Warning" "The battery is below 10% charge!"
                        aplay /media/WinData/windows/myprofile/Music/SndFiles/44MAGNUM.WAV > /dev/null 2>&1
                fi
        done

else
        echo "batteryalertDEBUG: Lock failed, check for existing process and/or lock file and delete - exiting." >&2
        exit 1
fi

exit 0

Thank you all for the help.

Marked as solved.

Can you explain how to do that please? I cannot understand what to do from the man xmodmap
The xmodmap file is used if you want to reassign the keyboard key values. For example, if you want the ctrl key to be caps lock and caps lock to be ctrl key. Or if you want Tab key to be an Enter key on the left side of the keyboard.
From your error log:
xmodmap:  /home/makem/.Xmodmap:1:  bad value "3  given for buttons list
xmodmap:  1 error encountered, aborting.

I swapped mouse button 3 and 1 to make my mouse left handed using the system Mouse and Touchpad Buttons setting. I had forgotten that some while ago I did that via xinput:

makem@ssdTOSH:~$ xinput --set-button-map 10 3 2 1
makem@ssdTOSH:~$

The file .Xmodmap in my home folder contains:

pointer = "3 2 1"

That file is dated 11/10/17 and as I always save my home folder between OS installs, that is probably when I first made the change using xinput. The entry in .Xmodmap is made by the system as far as I am aware so it added the quotes before and after "3 2 1". I have never done that.

I wonder if that is causing the error and if so I don't see how it can be corrected. If it works don't mess with it perhaps lol

The file is not being processed when it encounters this error. If there are any other settings in that file they are not being processed. If everything is working fine now, try renaming the file and re-logging in to see if there is any change.
