Hi! I'm having some trouble with my touchpad, so I figured I'd send a

[1.] One line summary of the problem:

Synaptics touchpad fail to be configured by HID RMI on a HP Pavilion
x2 (12-b003nf)


[2.] Full description of the problem/report:

Touchpad on the HP Pavilion X2 12" does nothing after boot. dmesg shows:

[    6.032160] hid-rmi 0003:06CB:7D29.0001: No 2D sensor found, giving up.
[    6.032273] hid-rmi 0003:06CB:7D29.0001: Error while initializing F11 (-19).

Your sensor is probably using the F12 2D sensor, not the F11. We are
aware of this issue, and patches has already been submitted. We need
them to be pushed upstream...

Meanwhile, if you can compile a kernel, you might be interested in:
- https://github.com/aduggan/linux/tree/development/hid-rmi (branch
  hid-rmi) -> this has been tested against F12 on RMI4 over HID
- https://github.com/bentiss/linux/commits/synaptics-rmi4-v4.8%2B (
  branch synaptics-rmi4-v4.8+) -> this is what matches the latest
  submission (the HID part has not been tested and thus not submitted)

Any help in testing would be appreciated! :)

Cheers,
Benjamin
