Public bug reported:
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
U: Uniq=
H: Handlers=mouse0 event5
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
