Msi B450 GAMING PRO CARBON AC

[veritas]

Does anybody know if this motherboard plays good with Linux?

I don't know for this exact model, but I've got a similiar one, namely the "MSI B450-A PRO":

$ inxi -F
…
Machine:   Device: desktop Mobo: Micro-Star model: B450-A PRO (MS-7B86) v: 2.0
…

Got a new PC a few days ago, installed Xubuntu 18.04 and it works quite well so far, for desktop and gaming use.
It also has an option to disable UEFI (enable Legacy) in the BIOS, which is perfect for Linux and other systems with bootloaders not signed by M$. I'd say that it's a similiar BIOS for both models.

Cheers
