ALPS Touchpad: No double click

[Anthem]

Hey all. I've just spent a few hours trying without luck to find info on how to get my double click working.

It's a Dell Inspiron 8600 laptop with an ALPS touchpad. I emerged synaptics, applied the kernel patch (2.6.9-r9), using EVDEV. There have been no problems whatsoever with the hardware itself. Single click (tapping) works perfectly, except the short delay between the tap release and actual click is a little bothersome. Scrolling is perfect.

The issue is that double tapping is a pain in the ass. I CAN get it to work ... if I'm lucky. Using synclient -m 10, I can monitor what's happening, and it happens like so:

I tap down, and it registers an event. I release, and it registers another. If, however, I tap down again before MaxTapTime (currently at 150ms), no event registers, neither on going down or up.

If I tap down and IMMEDIATELY after the up event occurs, I tap again, sometimes I can get the double tap to work. I've tried playing with the MaxDoubleTapTime value, and nothing I set it to seems to change this behavior, except if I set it too low (under 200 or so) I can't seem to get any double taps working.

Thanks in advance.

Both my mouse and touchpad worked fine from the start. I'm just started looking into how to disable the little pointer "clit" on my keyboard. I also did a Xorg autoconfig... I'm running on a DELL Latitude D800 so I don't thing our systems are THAT different. If I figure out how to configure the touchboard I'll let you know. This is the main part about touchpad that I have now.

here's how I have Xorg setup:

Section "InputDevice"

# Identifier and driver

Identifier "Mouse1"
Driver "synaptics"
Option "Protocol" "auto-dev"
Option "Device" "/dev/psaux"
Option "SHMConfig" "1"

Option "RightEdge" "925"
Option "TopEdge" "120"
Option "BottomEdge" "650"
Option "FingerLow" "10"
Option "FingerHigh" "11"
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" "1"
Option "CircScrollDelta" "0.1"
Option "CircScrollTrigger" "2"

EndSection

Like I said, the touchpad works perfectly, it's just the driver config that's an annoyance because of the doubleclick behavior.

Well, after perusing more forums and docs, I've come to realize that this problem I have is more or less the bane of all newer ALPS touchpad + synaptics driver users.

When I tried to let the alps kernel driver permit the touchpad to do click emulation, double clicking worked, but dragging didn't. When I tried this patch meant to solve the same issue (http://marc.theaimsgroup.com/?l=linux-kernel&m=109104309904873&w=2), dragging worked, but single clicks registered as double clicks.

For now, I'm going back to the old buggy behavior of having no double click emulation, since at least then I can still have my scrolling shortcuts.
