Most things are working now. Except for the touchpad which is new Elantech supposedly on PS/2. It says no touchpad attached and no multi gesture working not even scroll. I attached new debugfiles. I cannot get an ID for the device. In windows it seems to be attached to PS/2 but still no dev ID in there either.

Search for PS2 kexts for ELAN.

OK. Haven't really found anything working. What did you have in mind?
Seems the ones out there is old. Maybe the particular model is not supported.

I have no ELAN hardware here.
And the PS2 kexts for ELAN are closed-source, which I would never use anyway.

Therefore, nothing more to add.

Hello xayide,
i have exactly the same hardware (except 256GB NVMe WDblack).
what is working:
- Keyboard
- Trackpad (but no gestures)
- Audio (in & Out)
- Camera
- graphics acceleration
- WLAN & BT (changed to Broadcom)
- Ethernet

I am very interested on how you made your HDMI out working. Could you please advise? Thanks in advance.

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Hello,

I think the clover files are in my debug.zip in the bottom of the third post. I used T480 DSDT to get HDMI working and it is in the debug.zip. I havent come any further since then, the big problem is the elantech touchpad.
