            Bug ID: 103618
           Summary: Reverse Prime with intel/amdgpu leaves Intel monitor
                    blank
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: EoD at xmw.de
        QA Contact: intel-gfx-bugs at lists.freedesktop.org

        Depends on: 103613

I have a primary discrete AMD card (Tonga) using amdgpu and an Intel iGPU
(Skylake/HD530) using the intel driver.

I enabled DRI3 on both devices, but xrandr only shows the outputs/monitors of
the AMD card.

The main monitor (connected to the AMD Tonga) is active and shows a screen,
while the 2nd monitor (connected to the Intel iGPU) is already active but has
only a blank screen.

When I use "xrandr --setprovideroutputsource 1 0" it flickers a bit and xrandr
shows now all outputs/monitors.

When I try to enable the monitor connected to the iGPU via "xrandr --output
HDMI3 --auto" the 2nd monitor stays active but blank.

When I "extend" my desktop to the 2nd monitor I can leave the desktop with the
mouse, but the monitor is still just blank.


When I use modesetting on the intel card instead, everything works.


Here are further details, including the Xorg.log and the used configs:
