Thanks. Works now. I didn't know you had to do everything from the terminal.
I changed the virtual to 800x600, but when I restart without vga plugged in, the One is displaying at 800x600 instead of 1024. I can change the virtual setting back to 1024x600, but I'd like to not have to get root access every time I want to use an external monitor. I've been looking for a thread I saw a couple weeks ago before I had my One but can't find it.
Any solutions?
