journalctl output for amdgpu

Kernel version is 4.15.2

When enabling AMDGPU Display Core for my Gigabyte RX 580, I get nothing more than a blank screen on my HDMI monitor.

journalctl output for drm

> Feb 10 17:33:47 valmar-desktop kernel: [drm] Cannot find any crtc or sizes

This is the only error from the log that I can see.
Comment 2 Kyle De'Vir 2018-02-10 20:08:11 UTC
Is there anything I can do to get any interesting debug output?
Comment 3 Harry Wentland 2018-02-12 15:24:22 UTC
What monitor are you using?

Please recapture the journalctl with these options for the Linux kernel: amdgpu.dc_log=1 drm.debug=6
