Getting in to the system in text mode gives the chance to use keyboard, no matter if you have HDMI and/or DP. 

But after you try to startx, the system becomes unresponsive

We suspect a configuration problem.
Assigned to Olivier to give details.
Comment 4 Jairo Miramontes 2016-01-26 00:12:07 UTC 
Adding the maxcpus=1 option enables keyboard and mouse when connecting monitors, however the graphic interface breaks up really hard when using the mouse... it becomes very unstable
Comment 5 cprigent 2016-02-22 17:35:54 UTC 
Mouse/keyboard driver was missing
Comment 6 cprigent 2016-02-22 17:36:05 UTC 
So closed
