Problem with Synaptics Touchpad: Tapping does not work

[Yoichi Aso]

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.

[Solved] Problem with Synaptics Touchpad: Tapping does not work

[Yoichi Aso]

Hi Jason,

Thank you very much for your prompt and helpful reply !
The method on the page you pointed worked fine.

What I did was following.

I went to http://w1.894.telia.com/~u89404340/touchpad/index.html and 
downloaded the latest synaptics module for XF86/X.org, i.e. 
synaptics-0.13.2.tar.bz2 .
Then I extracted it and did
make; sudo make install

After that, I tweaked my /etc/X11/xorg.conf and restarted X.
Now I can use tapping and even edge scrolling !
Following is an excerpt from my xorg.conf FYI.

Thank you again, Yoichi.

You need to install a driver. This has been discussed many times on the
list. If you search the archives you can find the links to the driver.
