But I have 3 working vbioses and one custom. So problem only in modules, as everything other in zbook vbios is working.By changing the modules it changes some unknown items like that GPIO, and this change could contribute to the gpu not properly initializing or
Back to compare, this shows that only zbook vbioses are shorted. I even compare other PCIe desktop Polaris and they have those additional features in command modules, but hp Zbook doesn’t. For some reason hp deleted that info. Original vbios even glitchy on Ubuntu, but custom hybrid is working like it should be working!There is a big difference in how Mojave and Catalina X4000 kext initialize/reset the gpu, and I believe the answer may lie there.
I even forgot about Windows issues with multiple displays. I don’t know why hp done this, but their laptop vbioses are big problem...
