Comment 0 for bug 1778087

This is on an ASUS GL503VD laptop and would probably affect other ASUS laptops equipped with the ELAN1200 touchpad.

I am on Kernel 4.17.2 because older kernels did not enable the touchpad at all(It was just unrecognized or i2c-hid stopped the computer from booting)

The touchpad works but it has erratic behaviour and disconnects randomly. After it disconnects the only way to bring it back is to `modprobe -r hid-multitouch && modprobe hid-multitouch`

Libinput and synaptics can handle the touchpad though I found synaptics to be more stable.

dmesg gets spammed with this whenever I move the touchpad:
[timestamp] i2c_hid i2c-ELAN1200:00: i2c_hid_get_input: incomplete report (16/65535)

I tried to compile: https://github.com/mishurov/linux_elan1200_touchpad
Because from what I understand the "jumpy/disconnect" problem is associated to the incomplete reports and Mishurov managed to mitigate those. Unfortunately some symbols were deprecated in kernel 4.17.2 and it did not compile for my system.

While I can use my touchpad as is right now, and "restart" it with modprobe when needed, it would be nice to have it function bug-free. (Right after I typed this my touchpad disconnected and I needed to modprobe again, I am considering making a cronjob for that)

Let me know if anything else is needed. Will wait for an apport collection to add log files.
