Created attachment 78877

Xorg.0.log with drm-intel-nightly branch (cf. dmesg, above).

See my last attachment/comment (dmesg output) - this is the Xorg log that goes
with that.

By the way, I forgot to describe what/how I tested the software 
0) I booted the notebook with the external monitor & Apple connector NOT
connected,
1) then connected the adaptor to the VGA cable, 
2) then the connector to the DisplayPort.  No reaction. 
3) Then I opened the "Display Setting" (Gnome-3 settings panel) and clicked on
"Detect Displays".  I had dmesg -w running the whole time and first saw some
"*ERROR* Too many retries" messages on clicking "detect displays".  
4) I then disconnected the monitor/adaptor, and repeated the whole process,
only this time... 
5) I first connected the adaptor to the notebook, and 
6) then the cable to the adaptor, and 
7) then tried "detect displays", 
8) then diconnected the cable from the adaptor, 
9) then disconnected the adaptor from the notebook -- and 
10) then captured the dmesg output and the Xorg log.

Hope this helps.
