Touchpad Vertical Scrolling does not work

[WthIteh]

On the Ideapa Z360 with Ubuntu 10.10 and kernel 2.6.35-24-generic my touchpad
vertical scrolling does not work. All other features of it like tapping, dragging, etc. work well. But no vertical scrolling.

It is detected in xinput --list as PS/2 Generic Mouse instead of touchpad too.

Any idea?

hello, try this in terminal

synclient vertedgescroll=1

[WthIteh]

Thanks for the reply.
I used

synclient vertedgescroll=1

and it said

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

Any idea?

It's strange because I believe you do have a synaptics touchpad although the synaptics driver doesn't appear to be loaded. You should check your log to see what is happening, try this:

cat /var/log/Xorg.0.log | grep -i touchpad

I believe that it must be a synaptics one and detected somehow behind the scene. Since all of its features like tap-and-drag, etc. else of vertical scrolling works.
I tried

cat /var/log/Xorg.0.log | grep -i touchpad

And output was empty. I checked /var/log/Xorg.0.log log file more carefully and the only related part in it was

Which detects touchpad as PS/2 Generic Mouse.

And here is output of xinput for this device:

I found in other sites that synclient needs SHM enabled and enabling SHM requires fdi config under /etc/hal, but in my system there is no /etc/hal at all! Maybe related!?

And this is the result of an aptitude search for synaptics. It seems that the driver is installed.

i   xserver-xorg-input-synaptics                                                - Synaptics TouchPad driver for X.Org server

What should I do now?

Please help with this issue..... What could I do to solve it?

I have the same problem on my dell E5510. This problem (i.e. touchpad is recognised as ordinary mouse) has been around for a while, so it would be nice if the solution is found.

Interesting, but in older version of ubuntu (10.04) the problem did not exist.

Thanks for taking the initiative in finding the relevant xorg log data. It looks like your touchpad is being picked up entirely by the evdev driver. I made a suggestion on a similar matter in another thread that I still haven't seen a reply on so I'm not really sure if it will work. This will involve editing your xorg.conf so you shoud be sure to have a live cd handy so you can go in and fix it if you make a mistake.

Open up your xorg.conf in an editor and in the "ServerLayout" section add this line:

InputDevice    "Touchpad"  "CorePointer"

"Touchpad" will be your somewhat arbitrary identifier so it must match in the next section but you can use any identifier you want as long as it matches.

Now create a new "InputDevice" section

Section "InputDevice"
    Driver        "synaptics"
    Identifier    "Touchpad"
EndSection

The synaptics driver should be assigned to your touchpad. Save that and reboot. If it won't boot properly then there is something wrong with it and you need to use the live cd to go in and edit it.
