Making touchpad and resume password changes permanent

  • 772

in Ubuntu 10.10 I really don't want any password on resume on my EeePC, so I have to run

gconftool-2 --set --type=bool /apps/gnome-power-manager/lock/suspend false

and I want two finger middle click, so I have to run

xinput set-prop "ETPS/2 Elantech Touchpad" "Synaptics Tap Action" 8, 9, 0, 0, 1, 2, 3 (that gpointingdevice package can't do anything for me)

Those work, but only until the next resume. For some strange reason Ubuntu always overrides these changes.

I put both commands into a script in /etc/pm/sleep.d/ , but even then after resumes the changes are gone.

Where is this strange behavior coming from? And how do I make those changes permanent?

  1. You could add those commands in sh file 

    #!/bin/sh
gconftool-2 --set --type=bool /apps/gnome-power-manager/lock/suspend false
xinput set-prop "ETPS/2 Elantech Touchpad" "Synaptics Tap Action" 8, 9, 0, 0, 1, 2, 3

    save it as startup.sh(for example) and put it in System->Preferences->Startup Applications. Oh and add permission executing this file as program in file context menu->Permissions

  2. You should be aware that all sleep.d script run as root and could easily be the problem here.

    • You can add debugging information to your script such as echo "Touchpad command" which will then appear in the logs. More info

    • Open the logs by using Log File Viewer and find pm-suspend.log then search for the echo comments you added to your script and look for any errors.

    • If you need help deciphering the logs copy and paste them to dpaste and paste that link here.

    • You may be able to run these commands as another user with su username -c command

  3. For Ubuntu Oneiric, you should use the new hotplug-command hook. Basically, you create a script using this template that calls xinput with your desired settings somewhere in your path, make it executable, and then:

    gsettings set org.gnome.settings-daemon.peripherals.input-devices hotplug-command <script>

    The script will be called on startup, resume, and whenever the device is plugged/unplugged.

  4. I just added this as /etc/pm/sleep.d/99_touchpad (don't forget to chmod +x.) Works fine in Debian Wheezy so it should work the same in recent Ubuntu versions:

    #!/bin/sh
PATH=/sbin:/usr/sbin:/bin:/usr/bin
case "${1}" in
        hibernate)
                ;;
        resume|thaw)
        DISPLAY=:0.0 su <username> -c /home/<username>/touchpad.sh
                ;;
esac

    Substitute your own user name of course. My touchpad.sh (which is also called via "Startup Applications") is

    #!/bin/bash
dev="ETPS/2 Elantech Touchpad"
# Use xinput --list-props "ETPS/2 Elantech Touchpad" to list data
xinput set-prop "$dev" "Synaptics Tap Action" 8, 9, 0, 0, 1, 2, 3
xinput set-prop "$dev" "Synaptics Locked Drags" 1
xinput set-prop "$dev" "Synaptics Locked Drags Timeout" 500

    to set locked dragging and two-finger middle click.
