Execute a shell-script when closing laptop lid

Solution 1:

Use acpi:

The event is handled by acpi:

$ sudo nano /etc/acpi/handler.sh

I did something like this:


    button/lid)
        case "$3" in
            close)
                logger 'LID closed'
        USER=$(ps -C i3 -o user=)
        if test $USER; then DISPLAY=:0.0 su $USER -c "/usr/bin/i3lock -i /usr/share/pixmaps/Screensaver.png"; fi
                ;;

Automatically starts i3lock when i close my lid.
