Re: ASUS G752VS Touchpad does not work

Hi KT,
    We user kernel version 4.8 when test the G752VSK but it should
work at 4.10 too. I'll verify that later. And yes, there's no ELAN
interrupt at all from the bug report. I would suggest to have the DSDT
for further analysis.

Hi Chris,



Thanks, I remember this issue, it’s HID description issue for touchpad’s
physical button. And it fixed after Benjamin ’s patch

From below link, it seems the probe is ok, so I still guess interrupt maybe
the problem

which kernel version do you use for it?,



Thanks             KT

Hi KT,

   We only encounter Asus G752VSK: Default touchpad left key and right are
reversed issue. The touchpad works under hid-multitouch except the
left/right key reversed. I still have G752VS in hand, please let me know if
you need any.

Hi Chris,

Do you know ASUS G752VS's touchpad issue.
It's MS PTP, I am not sure if it meet the same problem that interrupt pin
configure issue?

From your last Acer PTP experience, Your issue seems caused by inconsistent
INT setting, right?

Could you give some advice to Kai-Heng to check the issue

Thanks  KT

Hi KT Liao, Duson Lin,

A user reported that the touchpad on ASUS G752VS does not work [1], it's
an ELAN touchapd.

I did the following change, the touchpad correctly loads elan-i2c instead
of hid-multitouch, but it's still not working.

[KT] I check the touchpad of this model, it's MS precision touchpad.
It must use "hid-multitouch", not "elan-i2c".

Well, the touchpad does not work under hid-multitouch, either. That's why I
tried to let it load elan-i2c instead.
What information do you need to investigate this issue?

Thanks.
