Comment 182 for bug 1275794

Using Fedora 20 with kernel 3.13.6-200.fc20.x86_64 I can now use my Lenovo T440s and the ThinkPad Pro Dock and 1 external monitor. However if I connect a second monitor it just gets a mirror of the first external monitor. I can connect the first monitor to VGA or DVI and that works fine.

xrandr output with two monitor connected (same output with only one external monitor):
