ALPS touchpad problem using Synaptics 0.14 Module


Hello everybody
Iam using a Debian Sarge 3.1 with a fresh compiled 2.6.14.4 kernel
My touchpad worked as a PS/2 mouse without any special features, so I installed the Synaptics package.

The touchpad now works fine with all the fancy features like scrolling and tapping.
But when I click on anything like an icon by tapping, The click is activated after a while (approximately a second).
The strange thing that this didn't happen before applying the Synaptics module.
It also doesn't happen when I click by the left-click button.

I tried every Option in the XF86Config file with no luck.
Thanks for help ..

Specs: (Dell Latitude D505)
1) AlpsPS/2 ALPS GlidePoint touchpad
2) Custom compiled linux 2.6.14.4 - (No unofficial patches applied)
(appropriate psmouse and evdev modules are inserted)
3) Latest Synaptics 0.14.4 module
4) XFree86 with configuration file as shown in the README.alps file in the Synaptics package
5) Debian Sarge 3.1

XF86Config: (Related part only)
Code:
Driver    "synaptics"
  Identifier    "Synaptics Mouse"
  Option        "CorePointer"
  Option        "Device"                "/dev/psaux"
  Option        "Protocol"              "auto-dev"
  Option        "LeftEdge"              "120"
  Option        "RightEdge"             "830"
  Option        "TopEdge"               "120"
  Option        "BottomEdge"            "650"
  Option        "MaxTapTime"            "180"
  Option        "MaxTapMove"            "110"
  Option        "MinSpeed"              "0.5"
  Option        "MaxSpeed"              "1.0"

These options like click delay, pointer speed and all this stuff is normally handled by the desktop and not by the X.
Open the KDE Control Center > Peripherals > Mice.
If you installed the synaptics package (and Ksynaptics) you can also find a special config menu for the TP.
OIf you use Gnome this should be also anywhere in the menus, either a special touchpad section or the mice menu.

No, It does not has relation with KDE or GNOME

Thanks for your trying to help. But this of-course does not has any relation with which window manager I use.
It's a modules related problem .. since using the standard generic PS/2 module solves this problem (and no availabe ALPS features implemented)

Mine is running quite fine on Kubuntu, it was also running nicely only with the PS/2 modules (evdev and psmouse). There is a difference with yours: Mine has the SendCoreEvents option turned on:
Code:
Section "InputDevice"
    Identifier "Synaptics Touchpad"
    Option "SendCoreEvents" "true"
    ...
EndSection
Try to see if setting this works.

Check also if the touchpad is set in the ServerLayout section (as "Synaptics Touchpad").
In Gentoo I used the option "CorePointer" instead of "SendCoreEvents" (the first needs no argument).

It seems this touchpad thingy has lot's of options, mine is running with the above code, but here is a step-by-step guide to set up the touchpad in Gentoo Gentoo-WiKi Synaptics Touchpad

Hope this helps
