However, it is still the case that using the BizLink diplay port adapter the monitor resolutions are not acquired correctly (while the command "sudo get-edid | parse-edid" provides the correct resolutions) and it is still the case that when plugging the monitor, often but not always the laptop fails to turn the external screen on (previously this often triggered a freeze). When the external screen fails to turn on, usually turning it off and then back on fixed the problem. This is still not ideal but it is a great improvement over kernel 3.16. I still get the following messages in the system log: [drm:intel_dp_start_link_train] *ERROR* failed to enable link training [drm:intel_dp_complete_link_train] *ERROR* failed to start channel equalization</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
