Ubuntu – Using AOC USB monitor on Ubuntu

driversmonitor

I have recently moved from Windows to Ubuntu 12.10.

I have an AOC portable laptop monitor (Model number e1649Fwu).

This monitor works solely through USB.

It works fine on Windows, but I cannot work out how to find/install drivers for Ubuntu.

I found this forum thread.

Any help would be greatly appreciated.

Update: It now displays the purple Ubuntu start-up screen but an error is displayed on the 2nd monitor when login is complete. I get Ubuntu as expected on my primary screen, and on the 2nd screen it gives a general protection fault. I followed the steps on this Ask Ubuntu question about installing a USB-link monitor, but the displaylink.c file throws C errors when I run ./configure && make && make install. I tried to fix these by modifying the C code, but no luck. I also tried using the xorg.conf file used in this tutorial, but this also doesn't work.

Am I right in thinking that it is just a matter of getting the xorg.conf file correct now?

This is a picture of the error shown on the second screen:

Since it's a DisplayLink device, try to use one of the how-to's for DisplayLink & Ubunut, e.g. How do I use a DisplayLink monitor?
