Synaptics TouchPad users might be interested in a specialized

and a new verion of GPM at:

If unsure, say Y.
To compile this driver as a module, choose M here: the

Say Y here if you have a Synaptics TouchPad connected to your system.
This touchpad is found on many modern laptop computers.
Note that you also need a user space driver to interpret the data
generated by the kernel. A compatible driver for XFree86 is available
from http://w1.894.telia.com/~u89404340/touchpad/index.html
The gpm program is not yet able to interpret the data from this
driver, so if you need to use the touchpad in the console, you have to
say N for now.
