10.10.3 Blank Screen after update from 10.10.2

[kevinh2]

My system was working fine until an Apple update in late March or early April. Now my Displaylink monitor is blank. The screen maps in my system settings, and I can move my mouse to the screen (although I can't see the mouse)

I uninstalled and reinstalled the 2.4.1b software, but still not working.

My DisplayLink device works because I tested it on another of my MacBook Pros.

I attached the log file. Hopefully I used it correctly to gather the needed info.

thx
