Laptops with larger touchpad area pose a serious problem with typing. While we explored a way to reduce the effective touchpad area, sometimes turning off the touchpad is a better solution. The 14.04 way of setting
synclient TouchpadOff to 0 or 1 doesn’t work on 16.04. So here’s a fresh technique with a little bit of scripting.
List all your input devices.
$ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ DELL Laser Mouse id=10 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)] ⎜ ↳ Sony Vaio Jogdial id=8 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Video Bus id=6 [slave keyboard (3)] ↳ Sony Vaio Keys id=7 [slave keyboard (3)] ↳ Power Button id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
The device of our interest is SynPS/2 Synaptics TouchPad. Note down the device ID (12 in this case).
Check the current status of the device.
$ xinput -list-props 12 | grep "Device Enabled" Device Enabled (139): 1
Now, modify the following script as per the IDs you see:
#!/bin/bash if xinput list-props 12 | grep "Device Enabled (139):.*1" >/dev/null then xinput disable 12 notify-send -u low -i mouse "Touchpad disabled" else xinput enable 12 notify-send -u low -i mouse "Touchpad enabled" fi
This script will take care of toggling the touchpad for you and notify the status. Copy it somewhere in your
$PATH. You can assign a keyboard shortcut to the script and toggle the touchpad state anytime you want.
