ubuntu 14.04: USB 3.0 Display Video Adapter: extreme slow
 

Hi,

I purchased i-tec USB 3.0 Display Video Adapter Advance TRIO DVI HDMI VGA FullHD+ 2048x1152 px External graphic card , I installed latest linux package for ubuntu http://www.displaylink.com/downloads/ubuntu.php 1.0.138 with dkms. The result is disappointing: both external displays 1650x1050 become very slow, I can't work fluently. Load increases up to 0,95 even if I type text only. I've a laptop with AMD A8-6410 processor and USB 3.0., 4GB RAM, Xubuntu 14.04. Standard background is covered by a white terminal. I'm disappointed. I turned back to one external display only.
