Title:
ELAN1200 touchpad jumps around and disconnects
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
