Solved HP Prodesk with AMD Ryzen 5 pro w/ Radeon Vega Graphics: Can't get Xorg working

[lasuit]

So, I just bought a used version of the above computer. FreeBSD 14.3 installs fine. But getting X to work has been frustrating. The docs say I should be using the "amdgpu" module. Unfortunately, that crashes the system. Here's what dmsg reads when I try to load amdgpu:

I would be happy to use the "VESA" drivers, but I get:

[   1555.256] (EE) No devices detected.
[   1555.256] (EE)
Fatal server error:
[   1555.256] (EE) no screens found(EE)

in my Xorg.0.log

There must be a way to make this work without the amdgpu module. Any suggestions

Generally as a fallback VESA is for old system console. For the newer vt(4) system console the corresponding driver is SCFB. vt is default console.

But really you don't want to mess with that un-accelerated driver. Radeon VEGA should work. Did you try RADEON driver instead?

Best advice I can give you is install drm-kmod package and delete all xorg conf files you created. Let the system detect card. drm-kmod contains all drivers.

For scfb the manual is clear what you need.

drmn0: Unable to locate a BIOS ROM drmn0: Fatal error during GPU init

This fail is due to BIOS setting.

Try turning off "Legacy BIOS"/ "CSM"booting and do "EFI Only" and check for other spots in BIOS with EFI/Legacy choices.
Jam all settings to EFI.

Phishfry, I did try the Radeonkms driver, but no luck. I have no config files in xorg.d because this is a new install. I've been through all the Handbook documentation, but nothing addresses this. I've also queried the forums looking for the same machine, but without much luck to my problem. Seems my system just doesn't like the driver.

Ok, I figured it out thanks to Phishfry. In fact, it was the BIOS, and it need to be updated. Once I did that the amdgpu module loaded without a problem. Thanks for pointing me in the right direction.
