--- Comment #42 from Ricardo Ribalda <ricardo.ribalda at gmail.com> ---
I have tried with a different screen (asus PB278) and a different notebook
(Thinkpad T420) and I am getting the same results.

A simple google search shows other people with similar problem:

https://askubuntu.com/questions/581574/ubuntu-14-low-screen-resolution-on-intel-hd-display

I believe that people simply does not know where to ask for help and simply use
their screens at lower resolutions. And not that many people know how to patch
and rebuild their kernels (or do not want to compile it for over an hour every
month).

I can make a patch that enables multi tries on intel_dp_start_link_train via
debugfs, that api does not need to be maintained.
I will post to the forums if enabling that option fix their issue and then you
can have more information for setting the bug priority.
