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:

⎜ ↳ USB OPTICAL MOUSE id=11 [slave pointer (2)]

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"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "SHMConfig" "on"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
Option "VertTwoFingerScroll" "on"
Option "HorizTwoFingerScroll" "on"

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.
