Hi,

A week ago I've reported a bug:
https://bugzilla.kernel.org/show_bug.cgi?id=195625 Is there anybody that can
help me with it?

I can have a look at it.
Please attach the full outputs of hid-recorder and evemu-record in the
bugs, or it'll be difficult for us to debug it.

I found out that some touchpads (and possible touchscreens?) are handled by
both hid-multitouch and hid-rmi drivers. Is there a way to verify how the
touchscreen would work on hid-rmi drivers? I've tested it with kernel
4.11.0-rc1 version where was this change:
279967a65b320d174a507498aea7d44db3fee7f4 HID: rmi: Handle all Synaptics
touchpads using hid-rmi
which was reverted in later kernel's version. On this version, only my
touchpad was handled by hid-rmi, touchscreen was still handled by
hid-multitouch. Maybe I should change something in code or in compilation
configuration to force hid-rmi?

Well, with 279967a65 applied, the system would know if the device can
be handled through hid-rmi or not. If hid-multitouch was still used,
that means that the device was not designed to be used as a rmi device
at all (i.e. hid-rmi will not be able to talk to it).

Cheers,
Benjamin

Or it is a wrong way to go? I would be grateful for your help.
