Please describe your issue in as much detail as possible:

I just installed SteamOS onto my home theater pc and for the most part it works perfect, except I can't access desktop mode. I click on Menu, Power, then Switch to Desktop mode, then I lose signal to my tv. My pc remains powered on but I have to unplug and plug it back in to get it working again. Boots into gaming mode without issue. This is a fresh install, no add ons or 3rd party software has been installed, and no settings have been changed.

My specs are as followed-

HP Prodesk 600 G4- (secure boot disabled)
i7-8700
16GB DDR4
AMD RX 6400

Steps for reproducing this issue:

1. Simply trying to access desktop mode freezes machine.
