Only two-thirds of my monitors are recognized by Linux.
I just set up Manjaro on my computer, following the Linux challenge, and I’m facing a recurring issue similar to what I experienced with Ubuntu and Fedora. Three of my monitors are working and recognized, but one is completely missing from the system, which happened across all other distros too. I suspect this is related to Linux since the main display shows up on the motherboard after startup, even though it shouldn’t. I have an XFX RX590 and a Ryzen 2600 processor. I believe the correct drivers are already installed (video-linux), likely because proprietary AMD drivers aren’t necessary for others.
You're unsure about compatibility but want to give it a shot. Your RX 480 works with two monitors, though the drivers might not be necessary. You can install them using the instructions at the provided link. Before installing, verify if the open-source AMD driver (xf86-video-amdgpu) is already present. Check your display settings—go to Settings > Displays—to confirm you're seeing only two monitors. Look for "Windowing System" in the About section; note that Manjaro defaulted to Wayland, but it had some issues, so you switched back. Try switching to X11 before logging in to see if that improves the experience. When you open a terminal and run `inxi --admin --verbosity=7 --filter --no-host`, it should display details about your graphics setup. Also, running `xrandr` should list all GPU ports.
