<pre>The problem not only affects X output (and the described xrandr symptoms), but
also happens when booting with framebuffer support: on my Thinkpad T440p, boot
halts entirely as soon the framebuffer switches to the higher resolution. Boot
only resumes when I lift the laptop momentarily from the docking station (with
DisplayPort monitor connected to it). Boot halts next when the console font is
switched; same process: it can only be resumed when I lift the laptop from the
docking station.
I can easily reproduce this behavior with the latest (2013.09) Grml live linux
system (<a href="http://grml.org/download/">http://grml.org/download/</a>).
Please let me know what further information I can provide to help solve this.</pre>
