'ELAN0618 Touchpad' is not recognized on a fresh install

[Mazen elkashef]

I tried ubuntu 16, 17 and 18. None of them were able to recongize my touchpad at all.
I tried to boot from a windows installation USB, the touchpad worked right away.

$ dmesg > ~/dmesg

Note: I got the touchpad manufacturer and model (Elan0618) by installing Windows to get more info as Ubuntu was unable to detect the touchpad at all.

I tried a million thing that I even can't remember. But I recently found this bug that might be related:
https://bugzilla.kernel.org/show_bug.cgi?id=81331

and also someone was saying that I could fix this by adding ACPI ID to drivers/input/mouse/elan_i2c_core.c (But I don't know how to edit the distribution and recompile it and all that stuff)

I installed the mainline kernel

$ uname -r
4.18.0-041800rc1-generic

Note: I can't login back to the default kernel that came with Ubuntu 18.0.4 TLS (Notice I updated the OS once)
$ dpkg --list | grep linux-image

I just installed the mainline 4.18 rc4 kernel, it does not work yet.

$ uname -r
4.18.0-041800rc4-generic

Alright. So are there any expectations about the timeline or the possibility of fixing this issue?
