This affects all kernels over 4.13, that is 4.14, 4.15, and so on. Affected are computers with current AMD hardware. My computer system: Motherboard: MSI X470 GAMING M7 AC CPU: AMD Ryzen 7 2700 Graphics card: MSI R9 380 If you want to use both monitors on top of each other, the ad management crashes and only one monitor is activated. The other monitor is deactivated and can not be reactivated afterwards. For all kernels under 4.13, ad management works perfectly. Affected are all Ubuntu / Linux Mint / Arch versions. It does not matter if you use Xfce, Mate, Cinamon or Gnome. The above stated versions have all been tested and delivered, with my hardware, the same results. I have found other users who have the same bug: https://www.linuxmintusers.de/index.php?topic=49574.msg698322#msg698322 Is this bug known and how can I fix it?
