This ended up being a BIOS+OS interaction issue. When booting to
Windows, it honored the Touchpad enable/disable button. Ubuntu doesn't.
I had to boot into the BIOS, and then hit this button once for it to
then be enabled again in Ubuntu.

Status in xserver-xorg-input-synaptics package in Ubuntu:

Bug description:
After an update from the following batch, mouse icon shows for a couple
seconds at login, then disappears. Moving finger on the touchpad or clicking
does not make it reappear before or after logging in, nor does the OS react to
these events:

Rolling back to prior kernel versions where this was confirmed working
didn't change anything.
Toggling the touchpad on/off button doesn't change this behavior.
This works fine in Windows.
As per cat /proc/bus/input/devices :
I: Bus=0011 Vendor=0002 Product=000e Version=0000
N: Name="ETPS/2 Elantech Touchpad"
P: Phys=isa0060/serio2/input0
S: Sysfs=/devices/platform/i8042/serio2/input/input9

B: PROP=5
B: EV=b
B: KEY=e420 10000 0 0 0 0
B: ABS=661800011000003
Strangely:
synclient | grep TouchpadOff
TouchpadOff = 2
Change this to:
synclient TouchpadOff=0
Confirm this via:
synclient | grep TouchpadOff
TouchpadOff = 0
Then touch the touchpad and notice:
synclient | grep TouchpadOff
TouchpadOff = 2
