in Dapper - Acer Aspire 1694 WLMi touchpad problems

[mihai.ile]

While in breezy the touchpad worked perfect now in dapper flight 5 has problems:
 *moving the mouse through screen sometimes jumps when you rais the finger and put it again in other place to continue the mouse movement.

 *Touchpad - Doubletap does not work corectly:
   *works when you open a file for example but does not work when you try to select the scrollbar and scroll or when you select the titlebar and want to move the window, instead maximizes/minimizes the window. i think that now doubletap releases the mouse even if you coninue the finger pressed after the second tap on touchpad.
This turns the use of touchpad really dificult and impossibile in some situations.
Also the touchpad has something like 4 buttons in a square that work like scroll up/down/left/right that does not work anymore.

I want to remember that all those things worked perfect in breezy. All of them.
For more informations about this laptop please read my report:

Hope you can fix this as soon as possibile.
If you need more informations please ask.

I can confirm this bug.
The synaptics touchpad is detected as a generic mouse on my Acer Aspire 1692 WLMi

i just recieved an email from Nacho de los Rios and thanks to his solution touchpad works great:
edit /etc/X11/xorg.conf
Add this section below the ps2 mouse's
Section "InputDevice"
       Identifier "Synaptics Touchpad"
       Driver "synaptics"
       Option "SendCoreEvents" "true"
       Option "Device" "/dev/psaux"
       Option "Protocol" "auto-dev"
       Option "HorizScrollDelta" "0"
EndSection

then add:
    InputDevice "Synaptics Touchpad"
in the ServerLayout section, for example:
Section "ServerLayout"
       Identifier "Default Layout"
       Screen "Default Screen"
       InputDevice "Generic Keyboard"
       InputDevice "Synaptics Touchpad"
EndSection

restart and it should work at least for acer 1694wlmi laptops.

Removing from xserver-xorg because it's a xserver-xorg-driver-synaptics problem

I meant to say xserver-xorg-input-synaptics, I really did.
