I have a new system with dual Nvidia Quadro RTX 4000 video cards. Fresh install of Fedora 33, Gnome desktop. I’m using the nvidia proprietary drivers, not the RpmFusion or nouveau drivers. Monitors plugged into the primary card are working, monitors in the secondary card are not. How do I get both cards working simultaneously?
Second question, once I have them working, how do I set up for mulitple displays instead of spanning the desktop across all displays?
