Okay, I've learned a few things. Using the following command:
I learn that my pointing device is identified as:
Then I can list the properties for the device using the command:
SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
One of the properties is listed as:
xinput list-props 11
According to the xorg archive,these two numbers (106 and 64) are used to compensate unequal vertical and horizontal sensitivity. Unfortunately, this is one of the few read-only properties of the device. I attempted to set the VertResolution and HorizResolution options (which are used to calculated the Pad Resolution) by creating the following 50-synaptics.conf file in my /etc/X11/xorg.conf.d directory:
Synaptics Pad Resolution (295): 106, 64
This fixes the touchpad issue, but unfortunately it also disables my keyboard.
Identifier "Synaptics TouchPad"
Option "VertResolution" "44.89"
Option "HorizResolution" "44.89"
