I have a laptop running Ubuntu 12.10, I have one external monitor connected using the vga port and it works fine. I want to get a second external monitor connected to it via a DisplayLink adapter. When I plug it in the screen turns on a goes green. But when I run xrandr this is what I get as output

I tried to download the display link drivers but they aren't being found. What is my next step here?

If you use the kernel 3.7.1 or the new version 3.9.6 it should work almost plug and play.

I was using Linux Mint 14 with kernel 3.7.1 and now I am using Linux Mint 15 with kernel 3.9.6 without any issues and the need to make extra tweaks. If you need to make some adjustments create a small script and execute it at the start up just like that:

!/bin/bash

xrandr --newmode "1360x768_60.00" 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync xrandr --addmode DVI-0 1360x768_60.00 xrandr --auto --output DVI-0 --mode 1360x768_60.00 --right-of LVDS1

Of course just use the specific requirements for your Displaylink USB resolution.
