Sensitive touchpad

Vaio laptops usually have ALPS touchpads which we can configure using gsynaptics.

First install it with
sudo apt-get install gsynaptics

then open /etc/X11/xorg.conf for editing
sudo nano /etc/X11/xorg.conf

and put this line into “Synaptics Touchpad” section you found there
Option "SHMConfig" "true".

The whole section should look like this:

Section "InputDevice"
Identifier      "Synaptics Touchpad"
Driver          "synaptics"
Option          "SendCoreEvents"        "true"
Option          "Device"        "/dev/psaux"
Option          "Protocol"      "auto-dev"
Option          "HorizEdgeScroll"       "0"
Option          "SHMConfig"      "true"
EndSection

If you have not this section in your xorg.conf (like on Intrepid), just add it using code above.
Then make logout and login back and run gsynaptics from menu System->Preferences->Touchpad.

P.S. Who knows how to make that double-quotes look like original in wordpress?

UPD: Sorry, we have ALPS touchpad in Vaio. But gsynaptics helps anyway. Post fixed.

UPD2: Mikko Tikkanen mentioned abouth another way how to turn it on

Hmm. Seems that the comment system stripped all the XML tags.. Besides, it seems that I accidentally removed the wrong line

Oh well, lets try again.
From this:
```
<match key="info.product" contains="AlpsPS/2 ALPS">
<merge key="input.x11_driver" type="string">synaptics</merge>
</match>
```
to this:
```
<match key="info.product" contains="AlpsPS/2 ALPS">
<merge key="input.x11_driver" type="string">synaptics</merge>
<merge key="input.x11_options.SHMConfig" type="string">true</merge>
</match>
```
Now, you should replace all the [ -brackets with appropriate angle brackets, so that it resembles XML.

The point is to add the SHMConfig true to different file. Hope I didn’t fuck this one up too.

Can you tell me where Mikko Tikkanen’s code is supposed to go?

Sorry, just realized that I’ve deleted too much =)
XML should go into /usr/share/hal/fdi/policy/20thirdparty/11-x11-synaptics.fdi.

I have a VGN-FW21M and I tried this setting unsuccessfully. When I try “dmesg | grep Alps” it returns nothing so I believe I have a different type of touchpad, but reading the output of dmesg, it seems the touchpad is not seen at all. Any hint on how to find a solution ?

I suggest you don’t modify xorg.conf in the latest Ubuntu release as the documentation says it’s and outdated technique.

We need to modify XML .fdi files in the hal folder. Here’s an explanation: http://bhagwad.com/blog/2009/04/configure-alps-touchpad-in-ubuntu-904-jaunty-jackalope.html
