I want to use my external monitor's resolution fully (2560x1440) with a USB display adapter for my laptop. I have one with Windows drivers, are there any adapter with linux / Ubuntu drivers that can give me full resolution?

I am thinking of something like my current USB to DisplayPort adapter.

HDMI only gives 1920x1200 (am using arandr to achieve this easily), and my laptop haven't got displayport. But I know that the graphic card can deliver 2560x1440 digitally or through an USB adapter.

The question is a year old, but the topic may still be of interest (March 2014): Official support from DisplayLink (one of the chipset manufacturers) is still disappointing (to say the least, see displaylinklinuxdriver.wordpress.com ).<br> Still the posting below from one device manufacturer summarizes current progress and deficiencies of the open source hackers' efforts. plugable.com/2014/03/06/… HTH –  user261906 Mar 25 at 12:43
    
Ubuntu 14.04 supports it. –  Dishank Jul 27 at 4:29

Right now, on Ubuntu 14.04, my Accell DisplayLink compatible adapter just works. It didn't work on 13.10.

Specs of this adapter: http://www.accellcables.com/J130B-001B.html

It seems a little slow on effects, I think that is because of being USB 2, and no acceleration? Anyway I got rid of the effects and works ok
