Hi. I have had Udoo duo for about a week now. Bought a micro sd card, a wireless keyboard and a mouse. I am using it with my secondary computer screen and it is working. The thing is that it is pretty slow. When the Kickstarter campaign was going on we got to see some pictures and videos of the developers showing the capabilities of the Udoo and often they would use the Duo and not the Quad. They were pretty impressive with high frames per second and what not. Now that I am using it simply to browse the net and install some software using the Ubuntu software center (which I installed my self) it is lagging and unresponsive. I am not sure if it simply is not powerful enough to handle this well or if there is something I am doing wrong. So I guess my main point is: HELP! What can I do to see if my system is doing something it is not supposed to do? Can you recommend commands to run for this and that to figure something out and to eliminate some possibilities. Thanks everyone.
