Configuring Touchpad Behavior


Hello,

I have Fedora 8 running on a Dell notebook which has an ultra-sensitive touchpad. When I am browsing the web using Firefox, occasionally I want to use the touchpad to scroll up/down a page. However if I accidentally swipe towards the lower-right corner of the touchpad, this in effect sends the browser a signal to go back to the previous page (and sometimes several pages).

Is there a configuration file that I can edit to disable certain "features" of the touchpad? All I want the touchpad to do is allow me to move the mouse pointer, and navigate up/down a page.

I recall that in the past when I dealt with Fedore Core 5, there was something I could do to set this up, but I'm not sure if the file I modified came with the OS, or if it came with a separate package I may have installed (perhaps tpconfig?). Either way, my FC5 system was waxed in favor of F8.

Your touchpad setup will be in the file /etc/X11/xorg.conf
Many touchpads use the synaptics driver, mine does.
Here is my touchpad section:
Code:
Section "InputDevice"
	Identifier	"Synaptics Touchpad"
	Driver		"synaptics"
	Option		"SendCoreEvents"	"true"
	Option		"Device"		"/dev/psaux"
	Option		"Protocol"		"auto-dev"
	Option		"HorizScrollDelta"	"0"
	Option		"MaxTapTime"		"0"
EndSection
I have disabled horizontal scrolling and Tap-to-Click
See man synaptics for the full range of options.

Tredegar, thanks for the tip. I personally like the touchpad tap capabilities, so I added the HorizScrollDelta option as you have, along with a few others that I gleaned from the man-page. My InputDevice section appears as follows:

Code:
Section "InputDevice"
        Identifier  "Synaptics"
        Driver      "synaptics"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "auto-dev"
        Option      "Emulate3Buttons" "yes"
        Option      "RTCornerButton" "0"
        Option      "RBCornerButton" "0"
        Option      "LTCornerButton" "0"
        Option      "LBCornerButton" "0"
        Option      "HorizScrollDelta" "0"
EndSection
My touchpad is now functioning to my liking. Thanks again!
