[Bug 782259] [NEW] ALPS touchpad on HP doesn't work properly, only with PS/2 emulation

 

Public bug reported:

Binary package hint: xserver-xorg-input-synaptics

I have HP Pavillion dm1 (1030s or something), with an ALPS touchpad.
The touchpad has never been correctly identified, but it provides a ps2
mouse emulation, which has worked.  The sensitivity is horrible, but
I've learned to live with that. Upgrading to natty, edge scrolling and
emulate3buttons disappeared, so I thought I'd investigate.

The current situation is as follows:

'modprobe psmouse' module gives (in dmesg):

[351174.694720] input: PS/2 Mouse as /devices/platform/i8042/serio1/input/input23
[351174.719260] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input24

'xinput list':
⎜   ↳ PS/2 Mouse                                id=15   [slave  pointer  (2)]
⎜   ↳ AlpsPS/2 ALPS GlidePoint                  id=16   [slave  pointer  (2)]

After enabling ShmConfig in /usr/share/X11/xorg.conf.d/, I can run 'synclient -m 1':
    time     x    y   z f  w  l r u d m     multi  gl gm gr gdx gdy
   0.000     0    0   0 0  0  0 0 0 0 0  00000000

...but nothing further happens, even if I move the pointer around with
the touchpad or click buttons, etc.

So that's where it stands.  How can I configure the touchpad so that it
is visible, and I can configure things like sensitivity?
