[nSLUG] Synaptics USB touchpad

Trying to get X working on an Acer Aspire E5-721 laptop. X starts,
displays clock and xterms as specified in ~/.xinitrc, xterm with focus
accept keystrokes, executes commands. X displays cursor but touchpad
doesn't move it or work at all.

Synaptics touchpad is seen by lsusb.

X is finding a driver and finding the touchpad (snip from Xorg.log
infra).  Modprobing the synaptics_usb kernel module doesn't help.
Running xev from the xterm with focus, xev doesn't show any events
from fiddling with the touchpad.

lshw doesn't mention the touchpad.

Many queries on the net about Synaptics touchpad not working quite as
desired.  Don't find anything about my situation.

Any suggestions?

Slackware 14.1, 3.10.17-smb 32-bit kernel.
