USB atheros NIC is missing from USB hub now. Is this a PCI remap issue? Trackpad is also working, however in a way I'd describe as jumpy. How do I tune this? 7490 too, maybe use the same setting and ELF file. Perfect sleep and graphics. Not work: Trackpad Jumpy too and the click buttons did not work. Cannot use a earphone, but the built-in speaker is OK. Link to comment Share on other sites More sharing options...

I tried SwitchResX and was able to bump up resolutions, but not to native 3840x1400. micheajp-v2.1.ioreg Link to comment Share on other sites More sharing options...

Graphics on laptop screen good, but I have a big monitor and it's not working at optimum res. As you say, the trackpad works but jumpy and no buttons. Focusing on monitor, then will go into audio and trackpad. Link to comment Share on other sites More sharing options...
persistz Posted January 23, 2019 Share Posted January 23, 2019 Another problem is about CPU frequency, I used Inter Power Gadget as a monitor and found the frequency is maintain about 3.1Ghz, which may caused the fan always rotating fast. Link to comment Share on other sites More sharing options...
persistz Posted January 23, 2019 Share Posted January 23, 2019 Update: I think the reason is ssdtPRGen.sh, in this repo, there is no info for i5-8250u, i will try to find the related info and run it. Update +: Generated ssdt.aml and place at paych, it did not work, the CPU frequency also maintain at 3.1G. Link to comment Share on other sites More sharing options...
