--- Comment #3 from Toni Spets toni.spets@iki.fi --- Created attachment 140414 --> https://bugs.freedesktop.org/attachment.cgi?id=140414&action=edit 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).
