That command only shows one of your cards, and not the other. It's simply not a command that gives you much useful information in this situation. > What xorg package I can uninstall? What on earth makes you think you need to REMOVE software in order to get the results you desire? What even makes you think you're not already using the AMD card? You need to check your X or Wayland logs before doing anything else. Maybe you're already using the card and driver that you want to use. If it turns out that you're not using the desired card, then there are a few things you can look into next: 1) lspci -nn Don't try to grep it or anything, because one of the cards doesn't show up with the characters "VGA" in its output. Just post both of the lines from this command, one for each card, which will give us the PCI ID to identify the hardware. 2) dmesg | grep -i firmware See if the kernel is trying to load any firmware and failing. If so, you will probably want to install some of the non-free firmware packages to support your hardware. This may involve adding contrib and non-free to your sources.list. 3) Google your PCI ID together with keywords like "debian" to see if there are any success stories for using your hardware on Debian. Usually you are not the first person to attempt something. Learn from those who came before.
