There’s an onboard graphics controller on this motherboard ROMED-8T. I have to have that enabled in order to get any graphics (it doesn’t seem to work with a PCIe card as the primary). But the onboard graphics is a DB15 and I’m trying to get an HDMI output, so I’ve added a PCIe graphics card (Radion based) and it shows up in lspci (with a radeon driver), but it does not show up in the graphical “displays” tool that let’s you enable/mirror/reorder monitors. I’m also not seeing it in the xrandr providers list.
How can I go about trying to enable this card to drive a second display?
It looks like xorg.conf is gone in Debian 10.5… it’s now a directory but doesn’t have the configuration information that I’m expecting to find in it.
