AlpsPS/2 ALPS GlidePoint touchpad not working in Ubuntu 15.10

I upgraded from Ubuntu 15.04 to 15.10 (Ubuntu GNOME) and noticed the touchpad is not working. The buttons and (vertical, horizontal) scrolling are working correctly. However, tapping (one, double tap, selecting text, etc) is not working. I have a laptop Dell Inspiron 1545. I'm pretty sure this was working in Ubuntu 15.04. There have been reports regarding touchpad issues in 15.10, although I don't know the specific issues.

This is the information I have been able to obtain:
