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 https://displaylinklinuxdriver.wordpress.com/ ).
    Still the posting below from one device manufacturer summarizes current progress and deficiencies of the open source hackers' efforts. http://plugable.com/2014/03/06/displaylink-usb-2-0-graphics-adapters-on-linux-2014-edition HTH     –  Mar 25 '14 at 12:43
  • Ubuntu 14.04 supports it. – Dishank Jindal Jul 27 '14 at 04:29
  • @ThomasLindvig Can you get 2560x1440 now with 14.04? – Andrew Jun 26 '15 at 17:46

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

Specs of this adapter: https://cdn.shopify.com/s/files/1/0396/6837/files/J130B-001B_manual.pdf

Copied from the manual:

This adapter features: -Supports up to 1920x1200 or 2048x1152 (wide) – 1920x1080 (VGA) -Self-powered design -Fully USB 2.0 compliant -24-bit true color

System requirements: USB 2.0 port, 40MB hard drive space, CD-ROM, 2GHz or Dual-Core processor minimum for Windows 7, Vista and Mac. Windows® 7 (64/32bit), Windows Vista (64/32bit), Windows XP (32bit) Intel-based Apple Mac running client versions of Snow Leopard 10.6, Leopard 10.5, Tiger 10.4

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
