What is the action when your laptop lid is closed: hibernate, suspend or do nothing? — Radu Rădeanu, Sep 04 '13 at 05:12
Did you find a way already? I try to do something similar: Disable touchscreen on closing laptop lid. So if you know a way please answer your own question here — rubo77, Sep 19 '14 at 11:13
@Rinzwind: this is last updated in 2012 and it seems really complicated — rubo77, Sep 19 '14 at 11:38
Considering that the lid closure dims the light and finally dims to zero...polling for the brightness value in the backlight folder in etc directory can help run a script at laptop lid closing.. — cafebabe1991, Aug 13 '15 at 14:36
Laptop Lid close is noticed by the Power Management system, which, happily enough, has hooks for additional user actions built in. This will get you started: less /usr/share/doc/pm-utils/* — waltinator, Aug 17 '15 at 18:11

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.
