outdoormagic Posted August 22, 2018 Share Posted August 22, 2018 I have 4 screens (A, B, C, D). A and B are Samsung, C and D and BenQ—not that that should matter. All are connected to AMD Vega FE. On 10.13.6, all 4 screens worked well. The system then booted from an internal SSD, HFS+. After installing Mojave, I could boot, but only got 2 screens. A and B would be on during boot sequence, then turn off and C and D would turn on for Login screen and after that. So all screens are recognized at some point, just not all together. Restored from 10.13.6 backup and I still get two 2 screens. Tried another backup drive and found that booting with HFS+, I get 4 screens, but booting with APFS, I only see 2. Then realized that Mojave converted my internal SSD to APFS. Nothing else appears to have changed. Same system (from backup), same Clover, same kexts. I have the latest Lilu, VegaFixup, APFS.efi, APFSDriverLoader, Whatevergreen. Tried VegaFixup and/or Whatevergreen. All boot, but 2 screens only. All points to the AFPS conversion affecting monitor drivers. Seems odd to me that switching from HFS+ to APFS would affect multi-monitor setups. Any ideas?

HBP Posted August 22, 2018 Share Posted August 22, 2018 make sure you are using the -lilubetaall flag on boot, everything you are describing points to Lilu and Whatevergrren not initializing/loading with the new 10.14.

outdoormagic Posted August 22, 2018 Author Share Posted August 22, 2018 Thanks, @HBP! That and resetting the NVRAM did it. However, it looked like hardware acceleration had disappeared. Finally solved that issue with -disablegfxfirmware. After the flag, I also removed VegaFixup and Whatevergreen. This didn't not impact functionality in any way that I can see. Thanks again! Time to reinstall Mojave...

If you are using the latest releases from github you do not need those flags anymore. 1 Link to comment https://www.insanelymac.com/forum/topic/335275-apfs-conversion-affects-multi-monitor-setup/#findComment-2631291 Share on other sites More sharing options...
