Comme= nt # 12 on bug 10591= 1 from tnmail= inglists@gmail.com 
I appear to have a similar issue, like comment #11, where the DVI-I port on my
380X seems to be detected as DVI-D when DC is on and I don't get display ov=
er
my DVI-I to VGA adapter (it works fine with amdgpu.dc=3D0). I'm also on Ubu=
ntu
18.04 and I also still experience this with the latest mainline kernel. The
Xorg log (extracts below) does still list the EDID for my display, identifi=
es
it as analog, and lists the new DVI-D port as connected when DC is on, but =
the
display doesn't turn on.

DC on:
[     7.312] (II) AMDGPU(0): EDID for output DisplayPort-1
[     7.312] (II) AMDGPU(0): EDID for output HDMI-A-1
[     7.313] (II) AMDGPU(0): EDID for output DVI-D-2
[     7.313] (II) AMDGPU(0): EDID for output DVI-D-3
[     7.313] (II) AMDGPU(0): Manufacturer: SAM  Model: 4e5  Serial#: 129769=
1186

DC off:
[     7.399] (II) AMDGPU(0): EDID for output DisplayPort-1
[     7.400] (II) AMDGPU(0): EDID for output HDMI-A-1
[     7.402] (II) AMDGPU(0): EDID for output DVI-D-1
[     7.440] (II) AMDGPU(0): EDID for output DVI-I-1
[     7.440] (II) AMDGPU(0): Manufacturer: SAM  Model: 4e5  Serial#: 129769=
1186

The system still works as expected with both keyboard and mouse, so X does
start properly otherwise.
This also happens with AMDGPU-PRO on Ubuntu 18.04 LTS.
