Now on Ubuntu HWE16.04 kernel 4.10.0-30

Problem persists. Unable to drive external monitors.

I was unable to start Xorg in gdb. I do 'service lightdm stop', but this does
not stop Xorg. Killing the process results in a new Xorg process being started.
I have not found out yet what is causing this behavior. Any clues welcome.
I will attach a 'ps -ef' output from after lightdm stop. This shows the related
X processes.

What I could do is reproduce this after login, then suspend the machine and
then resume. This produces a similar error and it brings up the Ubuntu error
reporting. I took some screenshots of this. Not sure this will help, but I will
attach it anyway, together with related logs and dmesg.
