thank you for the explanation Helmut!
so, as far as I can understand we can only wait until someone implements a
proper linux driver for this (Elan) device, is that correct?

hey Coybi,
unfortunately using the 'elan touchpad patch' didn't work because probably
MSFT0001:00 04F3:3140 is not an elan device.
with and without patch, no events are ever recorded by pressing or swiping the
surface of the TouchPad

I am really sorry (it might have been late at night :) ) that line it was
actually added by the kernel patch I prepared (I am building the whole kernel
using makepkg and patching is
but elan_i2c is not automatically loaded and even loading it manually
doesn't make any difference
if I blacklist i2c_hid, as proposed in other forums for issues with elan
touchpads, the touchpad even disappears from xinput devices
running out of options..

plus I found that this device is already defined in hid-elan.c, thus it
should be recognized as elan touchpad using elan_i2c module..

no luck man..
now I've got a hid_elan module loaded, but touchpad is still dead:
hid_magicmouse 20480 0
hidp 32768 1
bluetooth 737280 38 btrtl,hidp,btintel,btbcm,bnep,btusb,rfcomm
hid_elan 16384 0
led_class 20480 4
other info that might be useful are:
xinput list-props 20
Device 'MSFT0001:00 04F3:3140':
Device Enabled (177): 1
Coordinate Transformation Matrix (179): 1.00, 0.00, 0.00,
0.00, 1.00, 0.00, 0.00, 0.00, 1.00
libinput Natural
I am sorry mate.. touchpad still not working
I've checked and the patch has been applied correctly.
this is the output from lspci that shows hid_rmi is loaded, which is a step
ahead compared to yesterday ;)
```
lsmod | grep hid
hid_magicmouse 20480 0
hidp 32768 1
Thank you Coiby Xu! appreciate your support :)
unfortunately, even with your patch I could not make it to activate my touchpad.
I've created a kernel patch from yours, recompiled the kernel.
I tried both blacklisting hid_multitouch and removing hid_multitouch support in
kernel config. all
it seems not yet... :(
