I'm a relatively new user, too. I played with Qubes for a month or so a year or two ago, installing it on an external hard drive for a test run. It was too slow loading for me. I got a new laptop and put it on my SSD drive a month ago, and it's been working great.
I had the same issue with a second display. Here's what worked for me with an HP laptop. I plugged in the second display, then went up to the menu in the left side of the upper panel in the Xfce desktop, clicked on System tools -> Display and it was there. I used that tool to arrange things, and it worked fine. Since then, it's recognized whenever I plug it into the hdmi port, and a little requestor comes up asking me how I want to organize the displays. So, for me, at least, I had to do it using the display tool once, and then it worked fine. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
