report a kernel bug about ALPS touchpad to you.

My lenovo G360 has an ALPS touchpad, show in Windows 7 Home
Editition OEM in this laptop. Under Debian Squeeze or Ubuntu 12.04
LTS LiveCD in same laptop, the left and
right key, single and double tap, tracking  of touchpad works well.
But, there isn't touchpad tab in gnome mouse setting dialog, so I
can't setup edge scrolling and disable touchpad on typing. xinput
shows it is a "PS/2 Generic Mouse".

Tell me If need more detail information.

Thanks.  Forgive me for being dense: can you spell this out a little
more for me?

Is the following summary correct?

 - 2.6.32.y (Debian squeeze) works well, using xinput or synclient to
   configure
 - 3.2.y (Ubuntu 12.04 LTS) sees a generic mouse, unconfigurable
 - 3.2.y (Debian squeeze-backports) is likewise unconfigurable
 - 3.4.4 (Debian experimental) is also unconfigurable

No, none of these four kernels can configure a full functional ALPS
touchpad. Under all of these four kernels:
1, "synclient -l" shows "Couldn't find synaptics properties. No
synaptics driver loaded? "
2, "xinput --list" shows it is a "PS/2 Generic Mouse"
3, "cat /proc/bus/input/devices" shows it is "N: Name="PS/2 Generic
Mouse""
4, Can't find any string like "touchpad", "synaptics" in
"/var/log/Xorg.0.log" 
5, There isn't touchpad tab in gnome mouse setting dialog, so I
can't setup edge scrolling and disable touchpad on typing.

Could you provide full "dmesg" output from booting a working and
non-working kernel?

The laptop isn't here, I will post full "dmesg" output under "3.4.4
(Debian experimental)" kernel later.

Thanks.
