    Kubuntu now thinks I have three, rather than two monitors [13.04 to .10]

    Hi.

    I upgraded to Kubuntu 13.10 from 13.04 yesterday. Kubuntu now thinks have three monitors -- LVDS1 (my laptop screen), HDMI1 (my secondary monitor) and VGA-2 (the phantom monitor) . The "Display Configuration" program is adamant that this monitor is connected, it won't stay disabled on restart.

    Is there a way to remove this monitor, that doesn't involve reinstalling Kubuntu?

    Thanks.

    I have the same problem. I've not three monitor but only two. But is impossible to delete the "phantom" monitor. The problem is that very often when I open an application or a window this go to the second monitor, and I can't work or move it. Someone know the solution?

    Thanks, Francesco

      Two things, guys:

      xrandr --output VGA-2 --off

      will turn off the ghost VGA monitor. If you want specific help for a specific problem, you'll need to post specifics.

          I have the same problem. Actually there's a whole bunch of problems with the external monitor.

          Kubuntu 13.10, laptop with Intel HD3000.

          xrandr --output VGA-2 --off doesn't seem to do anything.

              I got it sorted out. Didn't at first realize that the HDMI was connected to the Nvidia card (I have Optimus, Intel HD3000 + GT520M). After installing Bumblebee everything now works at it should and the "phantom" monitor is gone.
