Ubuntu 17.10 daily build (2017-07-10), kernel 4.10.0-19
Booted from Live USB, without USB mouse connected: ELAN touhpad doesn't
work at all, but al least touchpad cursor is visible all the time. I've
tried to disable/enable the touchpad via system settings, but nothing
changes.
After that, I suspended my Asus G752VS laptop via shutdown/suspend menu
and then I disconnected the USB mouse. After waking up from suspend, my
ELAN touhpad magically became fully functional - everything works
fabulously.

the trick should work also with Ubuntu 17.04 but that's not my case. My
current Ubuntu 17.04 was installed while it was still in development -
so I will perform a new clean installation (without Windows) in the next
few days.

Hello,
I have just installed the new Linux 4.12 kernel.
My ELAN touchpad is still completely dead.
Please find attached the complete dmesg output file here (comment #75):

FWIW,
1. verify the return value of irq_get_trigger_type()
[ 4.478815] i2c_hid i2c-ELAN1203:00: Trigger type: 0
2. Force the trigger type to IRQ_TYPE_EDGE_FALLING with
irqd_set_trigger_type() before request_threaded_irq() 3. reboot with
your own kernel to see if it works.
I also set the type to IRQ_TYPE_EDGE_FALLING. But looks like it didn't
work for the user.
