Hi all,

I also see this when booting my docked Thinkpad X220 with two external monitors
connected via DVI (outputs HDMI2/3).

I'm running KDE with the new kscreen daemon. Interestingly it always fails on
KDE start with setting the second monitor (on HDMI2). Xrender claims the
everything is fine, but the screen just remains dark. When I redock everything
is fine again. I could imagine this issue is related.
