Installation of Qubes OS 4.0.3 requires the black screen workaround , after that almost everything works fine.
The only issue is the minidisplay output not working at all, but I’m convinced it’s a UEFI/BIOS upgrade related issue, as it started happening right after the update to 2.54 BIOS version. Other OSs present the exact same issue., including previous releases of Linux that used to work.
