Turning touchpad on and off using FN + F1 script not working

czepluch · 2013-10-20 02:10:51

Hi.

I have just bought a Sony Vaio Pro 13. I would like to be able to use FN + F1 to toggle the touchpad on and off instead of having to write the 'synclient TouchpadOff=1' command everytime i want to turn it off.

I have used the following scripts:

/etc/acpi/events/toggle-touchpad

event=button.fnf1 FNF1
action=/etc/acpi/actions/toggle-touchpad.sh "%e"

and

/etc/acpi/actions/toggle-touchpad.sh

#!/bin/bash
PATH="/bin:/usr/bin:/sbin:/usr/sbin"
export DISPLAY=:0
USER=`who | grep ':0' | grep -o '^\w*' | head -n1`

if [ "$(su "$USER" -c "synclient -l" | grep TouchpadOff | awk '{print $3}')" == "0" ]; then
    su "$USER" -c "synclient TouchpadOff=1"
else
    su "$USER" -c "synclient TouchpadOff=0"
fi

The code is from the arch wiki page for the given laptop that I am using [link]https://wiki.archlinux.org/index.php/So … ntallation[/link] and should work, but it does not work for me.

Is there an error in the code or is there just something that I haven't done to get this to work?

EDIT: And of course acpid is installed and added to systemd.

Does the script work if you execute it manually?

Also, check that the key is sending the code you expect.

When I execute it manually it says: "su: user does not exist".
This does of course give me a clue of whats wrong, but I don't know how to fix it. How do I check if a key sendt the code I expect?

Use acpi_listen in terminal to see if the key combo executes the acpi command you are expecting (i.e. FNF1). acpi_listen works something like xev. Start acpi_listen, then press the key combo.

Regarding starting the script file, I never used %e in the actions line. Try running the script toggle-touchpad.sh as root from terminal to test it. Make sure it's set as 'executable'.

The who command used in your example doesn't work on my install either. I'm guessing due to systemd.
Try replacing it with

USER=`loginctl --no-pager | awk '{ print $3 }' | head -n1`

I haven't tested it extensively, but give it a try.
