Linux/Ubuntu: The problem of the line!

In my last post I went through the steps on how to set up a dual-monitor system in Linux the way you wanted to. I had my laptop on the left side of my main monitor and I couldn’t get it right with the ATI Catalyst Control Center so I had to resort to a script that utilized xrandr.

I mentioned in my last post that I experienced a little problem though, an annoying 1-2 pixel wide line that pushed the desktop on my main monitor to the right. I don’t know why but I figured out what seemed to have happened. It seems that the auto resolution on the laptop monitor caused it to extend onto the main display. The resolution which was set was 1366×758. I didn’t think it would do any good so I joked with the idea of setting the resolution down to 1360×758, and I did for fun and it magically fixed everything!

The only thing is that I don’t know why I had to do that, because the resolution I have on my laptop screen in Windows is 1366×758 and it works fine with dual monitors. It’s a strange world…
