Run a script when laptop lid opens/closes

[usernametaken]

I want to automatically run a script when I close my laptop lid, just before it goes to sleep, and also run a script when I open the lid again.

Some distros have a lid.sh file in /etc/acpi/ that gets run automatically, but I don't see such a file on Fedora. I tried putting a file in /etc/pm/sleep.d/ but apparently those don't get run when closing/opening the lid.

I saw a couple other threads where people recommended installing gnome-tweak-tool, but I'm using KDE.

Any suggestions?

I would install the acpid package first. That will create two directories called /etc/acpi/events and /etc/acpi/actions.

Put a file called lidconf in /etc/acpi/events with these contents:

# run a script on lid open/close events
event=button/lid
action=/etc/acpi/actions/lid.sh "%e"

Now save your script as /etc/acpi/action/lid.sh. The script will receive an argument which will end with "open" or "close" (depending on whether, you guessed it, the lid was opened or closed), so you can test to see which case it is by starting the script with something like:

state=$(echo "$1" | cut -d " " -f 3)
case "$state" in
    open)
        # do what needs to be done when the lid is opened
        ;;
    close)
        # do what needs to be done when the lid is closed
        ;;
    *)
        # panic: not a state I know about!
esac

Once it is configured, you need to enable and start the acpi daemon with

systemctl enable acpid && systemctl start acpid

Hope that gets you started.

Awesome, thanks a ton!

Just a note in case somebody else runs into this issue: If acpid is already running, apparently you have to kill it and restart it for the changes to take effect.

I'm trying to use this script on fedora 22 to turn the touchpad on and off through gsettings command but it doesn't work, any ideas on how to make it work?
