drm_info output, from the working x11 session.

SUMMARY

Since the update the 5.25.0 i can't login to a wayland session anymore. The screen of my laptop is just black for ever, the external monitor doesn't even report a signal.  X11 works fine.

I have a multi GPU setup, i included the output of drm_info as an attachment. For more technical detail, the Laptop is a DELL G5 SE 5505.

STEPS TO REPRODUCE
1.  Run a dual gpu, dual monitor setup.
2.  try to login to a wayland session.
3.  See (actually see nothing)

OBSERVED RESULT

Black screen

EXPECTED RESULT

Plasmashell up and running

Comment 1 Linus Dierheimer 2022-06-16 23:08:04 UTC 
Seems to be a duplicate of #454086, just with HDMI instead of USB C here. But i am pretty sure it is the same root cause.
