Sleep mode on Thinkpad x201

[Alexandre Strube]

Actually, I noticed that this happen when the big display connected to the
displayport output of the docking station is turned on. The notebook wakes
up fine, but then the secondary screen is turned on, and Ubuntu wants to
send the image to it and dies. No keyboard, no nothing. But there is still
disk activity, god knows why. Still, I don't know to which component I
should open a bug against.
