            Bug ID: 105911
           Summary: DVI-D monitor connected to DVI-I output not detected
                    (regression from kernel 4.14.32 to kernel 4.16.0 using
                    graphic core)
           Product: xorg
           Version: 7.4 (2008.09)
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/AMDgpu
          Assignee: xorg-driver-ati at lists.x.org

I have a Radeon R9 380 and three monitors EIZO EV2436W. The graphic card has
four monitor output ports: DP, HDMI, DVI-D and DVI-I. Each monitor has a DP and
a DVI-D input port. Hence, one monitor is connected via DP, one monitor is
connected to the DVI-D port and the third monitor is connected to the DVI-I
port.

With kernel 4.14.32 all three monitors work. With kernel 4.16.0 and the new
graphic core (aka DAL) architecture the monitor that is connected to the DVI-I
port is not detected and stays dark.
