Overview

This page provides a list of capabilities for Synaptics-capable touchpads. The purpose for this information is to help others determine if their Synaptics-capable touchpad is able to use the multi-finger touch options. To find out the firmware, id, and caps information of the touchpad:

dmesg|grep Touchpad

This will provide information like:

[   10.975929] Synaptics Touchpad, model: 1, fw: 7.2, id: 0x1c0b1, caps: 0xd04731/0xa40000

In the example above, the firmware version is 7.2, the id is 0x1c0b1 and the caps is 0xd04731/0xa40000.

To find the capabilities:

synclient -m 100

This will start a application that will list the output coming from the touchpad. The format will look like the following:

    time     x    y   z f  w  l r u d m     multi  gl gm gr gdx gdy

The information that this document is gathering are 'f' and 'w'. The f will display the number of fingers and w will provide some other capability information (palm width, two-finger detection, three-finger detection, pen detection). In the example above, one finger is displayed and 'w' shows 4, 8, and 15 which states that it started with a finger then a wide finger or palm was detected. The 'w' column is categorized as follows (based on documentation from http://www.synaptics.com/decaf/utilities/ACF126.pdf):
