I'm relatively new to linux so I apologize if this ends up being a simple answer.

I have a Dell Inspiron 14 3452 laptop that is running Ubuntu 15.10. So far I have everything working except the touchpad. I have followed several forum and wiki posts trying to figure out the problem but still have not managed to get the touchpad working. From what I can tell it is detected and enabled but I get no functionality at all and have to use an external USB mouse.

cat /proc/bus/input/devices returns the following relevant device:

I: Bus=0011 Vendor=0002 Product=0007 Version=01a1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input7

B: PROP=5
B: EV=b
B: KEY=e520 610000 0 0 0 0
B: ABS=660800011000003

I appreciate any help getting this up and running. One other side note. The touchpad will sometimes stop getting detected after resuming from sleep and the system shows a Generic P/S 2 mouse instead. The only way I can tell right now is by running the above commands but I thought that could be a relevant detail.
