Multi-touch ALPS Touchpad

  Thread Previous • Date Previous • • Thread Next 
Dear All

There is some discussion on the notebook review forums regarding multi-touch
(ie two-finger zooming and scrolling) capabilty with the ALPS touchpads in
the Vaio Z. I've been reading and I've been trying to get this working under
Ubuntu 10.10 x64 on a VGN-Z590, however, I haven't had much luck yet. Based
on some information on the web I've tried using the pressure reading to
emulate multitouch. Nothing seems to work and I'm not sure if these rules
are working, I cant seem to use the synclient -m 10 to work which seems to
imply the SHMConfig variable isn't being changed. Any help would be greatly
appreciated

I've tried creating a udev rule /etc/udev/rules.d (these seem the be the
replacement for the HAL fdi policy files in the newer ubunutu - but I could
be mistaken)

ACTION!="add|change", GOTO="xorg_local_end"

ATTR{name}=="AlpsPS/2 ALPS GlidePoint",
ENV{x11_options.VertTwoFingerScroll}="1", ENV{x11_options.SHMConfig}="1",
ENV{x11_options.HorizTwoFingerScroll}="1",
ENV{x11_options.EmulateTwoFingerMinW}="7",
ENV{x11_options.EmulateTwoFingerMinZ}="90"

LABEL="xorg_local_end"

And a xml HAL fdi policy in /etc/hal/fdi/policy/


<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
  <device>
    <match key="info.product" string="AlpsPS/2 ALPS GlidePoint">
            <merge key="input.x11_options.VertTwoFingerScroll"
type="string">1</merge>
         <merge key="input.x11_options.SHMConfig" type="string">On</merge>
            <merge key="input.x11_options.HorizTwoFingerScroll"
type="string">1</merge>
            <merge key="input.x11_options.EmulateTwoFingerMinZ"
type="string">90</merge>
    </match>
        <match key="input.x11_driver" string="synaptics">
                <merge key="input.x11_options.SHMConfig"
type="string">True</merge>
        </match>
  </device>
</deviceinfo>

Neither of these methods seem to work. It would be great to have two finger
scrolling working but I can't seem to get it working.

Thanks very much,
Lyle
