Problem with Synaptics Touchpad: Tapping does not work



Hi,


My laptop has a Synaptics Touchpad and it worked fine with FC1, i.e. a
tapping on the pad was recognized as a left click, and with a double
tapping I could perform a drag.


But after I upgraded to FC2, the system doesn't recognize tapping at all.
Any tapping is just ignored, though I can still control the cursor
position by the touchpad.


Does any one have similar trouble or any suggestion ?


My laptop is Panasonic CF-T2: CPU Centrino 1GHz, Memory 768MB.
I also use a Logitech usb mouse as a pointer device.


The following lines are excerpts from dmesg and xorg.conf which (I
think) are related to this issue.


Thanks in advance, Yoichi.
