2 finger scroll with 2 T400 and Ubuntu
Hi!
I was trying to get two finger scroll working on my T400 with Ubuntu 8.10 installed.
Sadly I didn't succeed.
The output of synclient -m also always shows me that just one finger is detected.
That's kind of strange, as I thought every synaptics touch pad would support multi finger detection.
Is this a software or a hardware issue?
And is it solvable?
Thank you!

The touch pad does support two finger scrolling (I have it enabled). It should be as simple as adding the following to your etc/X11/xorg.conf, under the touchpad InputDevice section
Try that and if it doesn't work post your xorg.conf.
Code: Select all
Option "VertTwoFingerScroll" "1"

Thank you, Superego!
In Ubuntu 8.10 these options are not selected via xorg.conf anymore.
But I post the output of synclient -l
However, I think the problem is somehow more difficult than a wrong setting in xorg.conf, as the output of synclient -m 100 gives something like that
first I used one finger, then two then three.
As you can see, the f column didn't go above 1.
Have you got a suggestion?

Do you know if you have an ALPS touchpad or Synaptics? I don't know anything about the T400 or touchpad comes with it but I'm assuming it's a Synaptic. The reason I ask is because the ALPS touchpads, in general, have a hard time registering more than one finger.
Huh? You don't have/can't modify an xorg.conf anymore? Please clarify.Spindoctor wrote: In Ubuntu 8.10 these options are not selected via xorg.conf anymore.

In Ubuntu 8.10 it is not nessecary to edit xorg.conf anymore (you can do it anyway). By default, xorg.conf is nearly empty.
Instead HAL is used, meaning you create small xml-files with .fdi-extensions in a certain folder to do basically the same things you did with xorg.conf before.
Coming back to my problem with two finger scroll: in fact I don't know if I have a synaptics- or a ALPS-touchpad.
I also assume it's a synaptics but I don't really know.
How can I find out?
synclient -h says
So how do I lookup the kernel log and where do I find those information?
Thank you

Hardware properties:
Can't detect hardware properties.
This is normal if you are running linux kernel 2.6
Check the kernel log for touchpad hardware information.
Dirver version: 1502
Thank you

I don't know if this helps to determine if the touchpad is a Synaptics. Here is something I find in /var/log/Xorg.0.log:Spindoctor wrote:In Ubuntu 8.10 it is not nessecary to edit xorg.conf anymore (you can do it anyway). By default, xorg.conf is nearly empty.

Can you tell me how you enabled SHMConfig? I have not been able to figure out how to do that with the X server that comes with Ubuntu 8.10.
many thanks,

what do you mean two fingers scroll ?
with HAL the new configuration is at /etc/hal/fdi/mouse-wheel.fdi or something
for example mine has this
maybe you can add a line like this to have it work:
run the command to get you rinfo.product device name to put it there
with HAL the new configuration is at /etc/hal/fdi/mouse-wheel.fdi or something
for example mine has this
Code: Select all
<match key="info.product" string="TPPS/2 IBM TrackPoint">
<merge key="input.x11_options.EmulateWheel" type="string">true</merge>
<merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
<merge key="input.x11_options.XAxisMapping" type="string">6 7</merge>
<merge key="input.x11_options.YAxisMapping" type="string">4 5</merge>
<merge key="input.x11_options.ZAxsisMapping" type="string">4 5</merge>
<merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
</match>
Code: Select all
<merge key="input.x11_options.VertTwoFingerScroll" type="string">true</merg>
Code: Select all
