Thanks for the bug report. It appears the affected monitor is connected to the Nvidia GPU, but your system doesn't seem to have the Nvidia driver loaded properly. This might be an installation issue or it might be an incompatibility between needing 'modeset' enabled for the amdgpu driver, and needing 'modeset' disabled for the nvidia driver. I'm actually not sure what the best way is to support such a combination.
