Simpledrm is probably slow with this resolution, but that's an unrelated 
issue.

I hope to get one of the internal debug error messages that
  the DRM console prints.

In the attached log, the amdgpu driver is too noisy. Would it be 
possible to disable the amdgpu and radeon drivers for this test? So only 
simpledrm should be active. Likely this doesn't produce any graphical 
output and you may have to be able to login remotely to get the log.

Best regards
Thomas
