[Bug 105651] Vega64 doesn't output properly onto dell up2715k at 5120x2880

https://bugs.freedesktop.org/show_bug.cgi?id=105651

--- Comment #9 from Redsandro freedesktop@redsandro.e4ward.com --- @AlexDeucher I am using xserver-xorg-video-amdgpu. I can use 18.0.1 (No TILE support, need workaround) or 19.0.1 (Cinnamon crashes, need workaround for time being). I'm looking for a xorg config or xrandr command that works like nVidia's TwinView that I can keep in place while I am checking TILE support with this DM and kernel from time to time. (I am new to AMD/Radeon.)

@TomasBzatek I still need a workaround because Cinnamon crashes on 5.2 w/ 19.0.1 TILE support. See https://github.com/linuxmint/cinnamon/issues/8807
