To achieve this we make use of xinput command.
The following script will do the job. Create a new file paste the following.
1
2
3
4
5
6
7
8
9

#!/bin/bash
if xinput list-props 12 | grep "Device Enabled (142):.*1" >/dev/null
then
xinput disable 11
notify-send -u low -i mouse "Trackpad disabled"
else
xinput enable 11
notify-send -u low -i mouse "Trackpad enabled"
fi

Run xinput list
to find your device id:
1
2
3
4
5
6
7
8
9
10
11
12
|
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ HP Webcam-50 id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ HP WMI hotkeys id=12 [slave keyboard (3)]
↳ HP Wireless hotkeys id=13 [slave keyboard (3)]
|
Then run xinput list-props 11
where 11 is the id of your touchpad. Look for the line:
Device Enabled (142): 1
And change line two of the script to match.
Also do not forget to make it executable. Also notify-send needs a notification server backend running in the background. I use dunst for this purpose.
You can assign some key/key combination to execute the script. I mapped this script to F4. This can be achieved by different methods, xmodmap
being one of them.
