Description Philipp 2018-09-16 15:20:05 UTC
Description of problem:
The clickpad/touchpad and the touchscreen are not working or even loading kernel modules on my new convertible when running fedora 28.

Version-Release number of selected component (if applicable):
kernels 4.16.3, 4.17.17, 4.17.18, 4.18.7

How reproducible:
always

Steps to Reproduce:
1. use live-image or install of fedora 28

Actual results:
there is no touch input possible

Expected results:
clickpad input moving the cursor and typical effects of clicks, touching screen generating some activity

Additional info:
- platform is AMD RavenRidge
- Ubuntu 18.04 seems to have same problem, see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1787775
- in Win10, both devices (touchscreen and touch/clickpad) are powered by Microsofts generic HID-input driver released in 2006 and work like a charm
- touchscreen is from Wacom (device type 517e) [info retrieved from Win10]
- touchpad is from Microsoft/Synaptics (vendor msft, vid 06cb -> Synaptics, device id 0001) [info retrieved from Win10]
- accelerometer (ITE8396) on i2c bus works, it correctly rotates the screen
- disabling the keyboard when folding to tablet mode works as well
- pressing the "disable/enable touchpad" hotkey triggers correct on-screen feedback icon, yet has no effect in activating touchpad input

I tried various logs, none of them shows mouse/touchpad information. Please let me know, which specific logs might help you to help me :-) and I'm happy to add them to this bug report.

This https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1793230.html works for me, too.
Waiting for upstream (kernel) to include the drivers.
