This, unfortunately is not as true as I wish it was. I bought an RX 560 and tried to install Ubuntu 18.04. It could not propery drive my 4k display that uses DP 1.2 MST. That display has been working fine with a few different cards on Mac and Windows since 2014 when I bought it. I even tried the AMD pro drivers. Granted, the open source nvidia drivers couldn’t do it with a 1030 on 18.04 either, but the proprietary ones had no issue. edit: I should note, the RX 560 runs fanless up to 60c on Windows, but the fans always spin on Linux.

I have no problems running my RX 580 with the amdgpu driver and recent versions of Mesa.. If I had to guess, Ubuntu 18.04 has some archaic versions of both the kernel and userspace drivers.

  Do you have a 4K display that requires DP 1.2 MST? I tried the latest proprietary amdgpu-pro drivers also. I even bought the RX 560 because some other Linux users assured me the AMD Linux drivers were excellent. My post here is to help other people so they can make a more informed choice in the future.

It seems that support existed in KDE/Plasma workspaces in late 2014. https://www.phoronix.com/scan.php?page=news_item&px=MTg2NTY https://www.phoronix.com/scan.php?page=news_item&px=MTg2NTY Though if you follow the DP MST keyword there's still some corner cases being polished... https://www.phoronix.com/scan.php?page=search&q=DP%20MST https://www.phoronix.com/scan.php?page=search&q=DP%20MST https://www.phoronix.com/scan.php?page=news_item&px=DRM-Misc-Next-4.21-1 https://www.phoronix.com/scan.php?page=news_item&px=DRM-Misc... The Mesa drivers Ubuntu (and Debian, and many other distros) provide CAN be rather old. As you mentioned Ubuntu, follow the directions here to have a stack that's as updated as possible. https://github.com/ValveSoftware/Proton/wiki/Requirements https://github.com/ValveSoftware/Proton/wiki/Requirements I also tend to like checking Arhc Linux support page, but it doesn't seem to be helpful for this issue: https://wiki.archlinux.org/index.php/Radeon https://wiki.archlinux.org/index.php/Radeon
