Scroll with ALPS TrackPad

otisthegbs · 01-19-2005, 04:55 PM

I have an Acer TravelMate with an ALPS trackpad. I want to make the very right hand side ot the trackpad a scroll "wheel." Or maybe to hold a key and use the trackpad to scroll that way. There's a program called mouseemu that does exactly that but it's only for Macintosh trackpads.

In order to scroll using the trackpad you need to patch the kernel with the ALPS patch included in the Synaptics driver package.
My X config relevant to the touchpad looks like this:

Code:

Section "InputDevice"
	# ALPS Touchpad
	Driver		"synaptics"
	Identifier	"ALPS"
	Option		"Device"			"/dev/psaux"
	Option		"Protocol"			"auto-dev"
	Option		"LeftEdge"			"120"
	Option		"RightEdge"			"830"
	Option		"TopEdge"			"120"
	Option		"BottomEdge"		"650"
	Option		"FingerLow"			"14"
	Option		"FingerHigh"		"15"
	Option		"MaxTapTime"		"180"
	Option		"MaxTapMove"		"110"
	Option		"EmulateMidButtonTime"	"75"
	Option		"VertScrollDelta"	"20"
	Option		"HorizScrollDelta"	"20"
	Option		"MinSpeed"			"0.2"
	Option		"MaxSpeed"			"0.5"
	Option		"AccelFactor"		"0.01"
	Option		"EdgeMotionMinSpeed"	"15"
	Option		"EdgeMotionMaxSpeed"	"15"
	Option		"UpDownScrolling"	"1"
	Option		"CircularScrolling"	"0"
EndSection

Scrolling works well for me using this setup.

My Scrolling is now working with the configuration u gave in this topic. but one question please, which option do i have to "comment" (#) to disable the TAPPING? (i already comment "MaxTapTime" and "MaxTapMove" but still tapping.

thanks.

(By the way, on my Compaq Presario R3000Z, with SuSe 9.2 i had to pu "Mouse[1]" instead of "ALPS" con the Identifier Section.) --> this is just for anyone who may have the same problem as me.
:P

i ll be waiting, thanks.
