--- Comment #55 from freeseek <giulio.genovese at gmail.com> ---
The situation is still not improved with Ubuntu 14.10. However, with kernel
3.16.0-23-generic I get a somewhat different output in dmesg (this is when I
switch off the laptop screen to have the output only on the external monitor):
[ 47.631564] [drm:intel_dp_start_link_train] *ERROR* failed to enable link
