Move window in dual monitor setup

  • 772

I'm running a dual monitor setup, with one of the monitors most of the time in standby, but connected (it's a TV). It works fine if both are turned on, but when the monitor is in Standby mode some windows still open on that screen. Where I can't see the window to select it and drag it back to the correct screen.

As I'm running Ubuntu 14.04 with Unity, I can't select the invisible windows either, because the Unity Launcher only shows application windows on the current screen/workspace?

What I can do however is use Alt+Tab to select the window and then drag it back with alt+f7. But this is quite a hassle if you have to do it with a lot of windows. Sometimes I resort to just pulling the cable from the back of my pc, which does move all the screens into the correct screen.

So is it possible to:

  1. Make the Windows open on the screen that is actually on and not just connected in Standby mode.

  2. Make unity show all windows in the launcher (I don't even have the launcher enabled on the second screen?).

  3. Have a shortcut to move the screens back to the correct screen in one go.

I have an ATI graphics card with proprietary drivers and the always on screen is the primary screen.

Thanks!

P.S. output of xrandr:

DisplayPort-1 disconnected (normal left inverted right x axis y axis)
HDMI-0 connected 1920x1080+1920+0 (normal left inverted right x axis y axis)
DVI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis)

    Based on your (truncated, I think) xrandr output, this command will turn the screen off:

    xrandr --output HDMI-0 --off

    And this one will turn it back on:

    xrandr --output HDMI-0 --mode 1920x1080 --right-of DVI-0

    Test them and if they do indeed turn the screen on and off correctly, assign a shortcut to each of them and you'll be able to turn them on/off at will.
