I've got a script that is executed in order to have suspending/resuming working in my laptop. Then I have another series of xinput,xkbset and xmodmap commands that are executed when I initiate a session to have two-finger scrolling and keyboard shortcuts set up. When I resume from suspend, two-finger scrolling and my keyboard shortcuts won't work. I need to manually execute the commands in the second file again. How can I add those to the suspend/resume script to have this done automatically? See below:

          if [ ! -L "$DDIR/$dev" ]; then

You can place your scripts in the /etc/pm/sleep.d directory to have them run after suspend. You will need to add a conditional to make your script run only during resume and not during the suspend process as well. For example, your touchpad script would look like:

case "${1}" in
    resume|thaw)
        DISPLAY=:0.0 ; export DISPLAY
        xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Two-Finger Scrolling" 8 1
        xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 8 1 1
        xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 32 10
        xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 32 8
        setxkbmap -layout gb
        xkbset m
        xkbset exp =m
        su $USER -c "sleep 3; /usr/bin/xmodmap -e "keycode 135 = Pointer_Button2"" &
;;
esac

Be sure your script is marked globally executable and change $USER to the corresponding username.

You can find more detailed information in the pm-suspend manpage (man pm-suspend) or by looking at the documentation in /usr/share/doc/pm-utils (particularly /usr/share/doc/pm-utils/HOWTO.hooks.gz).

How do I need to call this script if the suspend/resume is called 20_something? –  213441265152351 Jan 3 '12 at 10:50

It can be called whatever you like. It's a good idea to start it with a number between 00-49, per the pm-suspend manpage: "00 - 49 User and most package supplied hooks. If a hook assumes that all of the usual services and userspace infrastructure is still running, it should be here." –  fader Jan 3 '12 at 13:28

This is still not working for me... Any suggestions? –  213441265152351 Feb 10 '12 at 11:23
