How to Disable touchpad while typing on Aspire One

  • 772

I want to disable the touchpad while I type on my Aspire one netbook. If I issue the command syndaemon the synaptics driver is not detected:

Unable to find a synaptics device

So, I added the following to my xorg.conf file:

Section "InputDevice"
Identifier "Mouse0"
Driver "synaptics"
Option "Protocol" "auto"
Option "Device" "/dev/input/mouse0"
Option "ZAxisMapping" "4 5 6 7"
Option "CorePointer"
Option "HorizEdgeScroll" "1"
EndSection

It is still unable to find a synaptics device, however my touchpad works fine.

  1. on my lap-top I just go to the System > Prefrences > Mouse and under the Touchpad tab make sure Disable touhpad while typing is checked... after that it automatically disable the touchpad whenever I am typing... pretty cool if you ask me...

  2. You may try reverting the change you did (or keeping it) and installing the gpointing-device-settings package, which will provide more configuration options for your touchpad. Since Ubuntu 10.04 LTS this package replaces gsynaptics, if I remember well.

    sudo apt-get install gpointing-device-settings

    Once installed you can find it under System -> Preferences -> Pointing Devices.

  3. from https://help.ubuntu.com/community/SynapticsTouchpad

    The following example invokes syndaemon for 4 seconds after any keyboard activity (-i 4), except when modifier keys such as Alt or Shift are used (-K), and only disables tapping and scrolling (-t) for this period.

    syndaemon -i 4 -d -t -K

    add this to your Startup Applications

  4. On my Aspire One netbook, I can just use Fn+F7 to disable and enable the touchpad.

  5. Some touchpads emulate a mouse in their hardware/firmware, and because of that still (partially) work even if they aren't recognized as "touchpads".

    If GNOME detects a touchpad, it will show the tab in the Mouse preferences as TheX explains.

  6. First entirely undo the current setting: Remove the tick for Disable touchpad while typing in Mouse & Touchpad settings.

    Now search for and open Startup Applications from the Dash. Click Add.

    Name: Syndaemon

Command: syndaemon -i 1.0 -K -R -t

Comment: Disable touchpad while typing, with a reasonable delay and only for tapping and scrolling

    The -i 1.0 parameter sets the idle time of the keyboard to 1s. -K option ignores the Modifier keys. -R option uses the XRecord extension for detecting keyboard activity instead of polling the keyboard state. -t option disables tapping and scrolling but not mouse movements.

    Click Add and then Close.

    Reboot your computer.

    Note: this is a user preference, so repeat this in every user account.
