dmesg of a boot with one suspend cycle
This dmesg contains a suspend immediately after the system was booted up. After
resuming both displays lit up and showed the last image before the system was
suspended. The system was completely unresponsible for a while.
Once it was working I had the Xfce hotplug window open and I clicked the extend
button which again got the system stuck for the same amount of time. The
displays were already correctly arranged so it was unneeded but it also
triggered the issue.
As a bonus xrandr shows three outputs connected when I have only two. I'll
attach output of both (DC and non-DC).
