            Bug ID: 297136
           Summary: FreeBSD loses screen on X870 Tomahawk motherboard when
                    using the NVidia graphics card
           Product: Base System
           Version: 15.1-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: misc
          Assignee: [email protected]
          Reporter: [email protected]

The embedded AMD graphics controller is turned off in favor of the NVidia c=
ard.
This NVidia card worked with FreeBSD w/out a problem on another, older MB.

The Beastie screen appears, the user makes the choice 1 and then the screen
becomes dark.

The expected behavior: FreeBSD should boot normally by default.

The Gemini AI recommended the following snippets but none of them helped:

set hw.efi.fb.provide=3D0
set screen.textmode=3D1
boot -s

hw.vga.textmode=3D"1"
machdep.disable_mtrrs=3D"1"

set hw.vga.textmode=3D1
set kern.vty=3Dsc
boot -s

hw.vga.textmode=3D"1"
kern.vty=3D"vt"

set hw.vga.textmode=3D1
boot -s

gop list
gop set {N} # some simple low resolution
