Hi,
Dear kernel developers.

According to the advice at " http://bugs.debian.org/679750 ", I 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". Below is the detail information.

System information:

Debian Squeeze, tried kernel: 2.6.32-45, 3.2.4-1~bpo60+1,
3.4.4-1~experimental.1
And tried Ubuntu 12.04 LTS LiveCD, kernel: 3.2 (has the same bug as in
Debian)

The below information come from Debian Squeeze with 3.2.4-1~bpo60+1 kernel.
The other kerneld and sytem tried above should has the same result.

"synclient -l" shows:

Couldn't find synaptics properties. No synaptics driver loaded?

"xinput --list" shows:

There is no touchpad or synaptics information in the "/var/log/Xorg.0.log"

I have tried too many methods found on internet, such as:

1, add "psmouse.proto=imps(or exps)" into kernel parameters;

2, add file "etc/X11/xorg.d/10-synaptics.conf", the content as below:

Section "InputClass"
    Identifier      "touchpad catchall"
    Driver          "synaptics"

3, Thanks to the help of "How to disable Alps touchpad while typing or when
using an external mouse in Linux" at:
http://www.imega.cz/Linux-Alps-Touchpad-Dell-E6410/Linux-Alps-touchpad-disable.php
I resolved the problem of "disable touchpad on typing" by using a python
script, but I can't make edge scrolling work yet.

According to the advice of the page above, I downloaded linux-source-3.2,
and applied patch at " https://patchwork.kernel.org/patch/118834/ "), I
have not use cat *.patch | patch -p1, just copy the modified code into
linux-source-3.2 and recompile psmouse.ko. But no lucky, edge scrolling
can't work.

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

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

Hope that helps,
Jonathan

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.

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

Thanks.

ALPS refuses to provide information about their touchpad protocols, so
any support we have for ALPS touchpads is based on reverse engineering
the protocol. It's likely that yours uses some version of the protocol
that isn't supported, in which case someone with access to the hardware
will need to do the reverse engineering work.

There's a slight chance that it uses a known protocol but just has an
unknown model signature. In that case the fix is easy, but it will
require some trial and error to see if that's the case.

When you send dmesg it would help if you could use a build with the
following line added to the top of drivers/input/mouse/alps.c, before
the includes.

 #define DEBUG

This will cause the model signature for your touchpad to be included in
the log.
