How can I get a DisplayLink USB monitor work under Ubuntu?
Solution 1:
On Aug 3, 2015, Displaylink finally released the USB Monitor driver for Ubuntu.

I have an AOC usb monitor and Ubuntu 14.04. After installing the driver, my usb Monitor start working.
If the driver works for your monitor, please let other people know by posting it. Many people waiting for this driver. I've been waiting for 2 years. :-)
Solution 2:
Maybe this will get you a little bit further.
General DisplayLink adapter information for Linux is available here.
Also, if your primary graphics adapter is from NVIDIA, you should read this.
Good Luck
