<pre>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:
