"EDID Invalid" On Xubuntu 16.04

[TomStaels]

i was trying to get it to work with udlfb, since this seems to be a "Bad Idea" (tm), I tried udl :

$ lsmod | grep "udl"
udl                    32768  1
drm_kms_helper        147456  2 udl,i915
drm                   364544  7 udl,i915,drm_kms_helper

Turning ON the "Unknown Display" in Displays, the system becomes nearly unresponsive, and the display never actually turns on.
syslog is spammed with :
