<pre>I appear to have a similar issue, like <a href="show_bug.cgi?id=105911#c11">comment #11</a>, 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 over
my DVI-I to VGA adapter (it works fine with amdgpu.dc=0). I'm also on Ubuntu
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, identifies
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#: 1297691186
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#: 1297691186
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.</pre>
