Lenovo C630 4K UHD Touchscreen Not Detected #550

Open githububub opened 4 years ago

githububub commented 4 years ago

C630 Pantheon. 4.16.18-galliumos. ISO install with full firmware and ISO install with legacy firmware. Combing through dmesg logs of both C630 devices (one with full and the other with legacy firmware) the closest thing we come across is:

drm:wait_panel_status [i915]] ERROR PPS state mismatch

Perhaps the module(s) required for the C630 4K UHD touchscreen are not built into the kernel (or removed in the build config)? Everything else works as expected (more or less) just not touchscreen capabilities. Any suggestions as to what can be modprobed into the system to test?

UPDATE: Touchscreen works on debian-live-10.3.0-amd64-xfce+nonfree. Anyone have a list of Gallium OS nonfree apps to diff with the Debain list to help determine the proper driver to install?

@githububub out of interest do speakers and microphone work on debian? I have the C630 (1080p version) and the sound and microphone doesn't work

@githububub also how did you install Debian?

Debian 10 is using a newer kernel than Gallium's 4.16 which is why it has broader/newer hardware support. There are a couple requests in motion to test and upgrade the kernel to a newer one in the 5.x series which will probably fix this.
