Reconnecting Trackpad on wake up from sleep

Dear all,

I have laptop that is mostly great with Ubuntu but sometimes when it wakes from sleep the mouse buttons above the trackpad don't work.

Its a Lenovo Thinkpad X1 Carbon (6th gen with the high res screen).

To get it to work again I run the following little script.

Code:

#!/bin/bash

echo -n "none" | sudo tee /sys/bus/serio/devices/serio1/drvctl

echo -n "reconnect" | sudo tee /sys/bus/serio/devices/serio1/drvctl

I tried putting this in a pam utils script, below, but it doesn't work. Anyone know where I might have gone wrong?

I put it here /usr/lib/pm-utils/sleep.d/95-trackpad

Code:

#!/bin/bash

#reconnects trackpad after sleep



. "${PM_FUNCTIONS}"



case "$1" in

    resume|thaw)

        echo -n "none" | sudo tee /sys/bus/serio/devices/serio1/drvctl

        echo -n "reconnect" | sudo tee /sys/bus/serio/devices/serio1/drvctl

    *) exit $NA

      ;;

esac



exit 0

You are missing ;; on resume|thaw)

Oooo, I am indeed. I hope that is it. :)

So, figured it out. I was missing the ;; but also it was in the wrong place.

My script needed to be in /lib/systemd/system-sleep/ and the script is below with a quick thing to check it is running which can be removed.

Code:

#!/bin/bash

#reconnects trackpad after sleep



case "$1" in

    post)

        echo -n "none" | tee /sys/bus/serio/devices/serio1/drvctl

        echo -n "reconnect" | tee /sys/bus/serio/devices/serio1/drvctl

        echo "ran2" >> /var/log/track.log

        ;;

esac
