This is almost certainly related to the following entry in xserver-xorg-input-synaptics' debian/NEWS file:

xserver-xorg-input-synaptics (1.1.1~git20090510-1) unstable; urgency=low

  * Tapping has been disabled by default on many touchpads by upstream, see
    the "NOTES" section in the synaptics(4) manpage for a short overview
    about how defaults are calculated.
    If you want to re-enable it, you can do so from within the X
    environment by running the following commands in a terminal:

        $ synclient TapButton1=1
        $ synclient TapButton2=2
        $ synclient TapButton3=3

    Note that the configuration will not be permanently modified, to do
    so assign the above option values in your xorg.conf or custom fdi file
    (see the synaptics(4) manpage or the documents in
    /usr/share/doc/xserver-xorg-input-synaptics for additional details).
    Another alternative is to use desktop environment specific tools
    like gpointing-device-settings or touchfreeze.

Max, I can confirm that the commands above re-enable tap-to-click on my T42.

Note that the gnome-control-center task exists to represent the need to assess whether gnome-mouse-properties needs changes to integrate nicely with the synaptics change mentionned above.

Hello Everybody,

I confirm you the solution from Max Bowsher it is working fine in my laptop Dell Inspiron 1420. However I don't know why my xorg.conf file is blank, I need put here the new configuration for my touchpad, but it is empty.

Somebody knows about the new changes in Karmic Koala for why the xorg.conf file it is empty?

Best Regards,

Francisco Barrientos
