I ran the command again and this was the output: 

Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event5
Move one finger around the touchpad to detect the actual edges
Kernel says:    x [1270..5659], y [1114..4764]
Touchpad sends: x [1243..5759], y [1130..4832] \
^C

Touchpad size as listed by the kernel: 89x54mm
Calculate resolution as:
        x axis: 4389/<width in mm>
        y axis: 3650/<height in mm>

Suggested udev rule:
# <Laptop model description goes here>

If when I run the command which should enable edge scrolling, it doesn't get
enabled. Although 2fg scrolling stops working, no way of scrolling is enabled.
Now I can't scroll at all.

This might not be the case as your command wasn't working either.

Also, sorry for keeping you waiting so long, I've been very busy.
