See also #16, which addresses this same issue, with a slightly different approach. I'm not sure which will perform better.

I think my solution is better, but both are similar.

I vote for this approach instead of #16. It is not always reasonable to turn off all displays first.
On the other hand, it would be much faster to do all the turnoffs in a single command, then let a second command activate outputs.

Note, that this approach also can turn off all displays first, depending
on configuration.

EG, when you switch from LVDS+VGA to HDMI, or LVDS to VGA+HDMI. It will
turn off LVDS first, next turn on VGA and HDMI.

However - it works ;)

I made a pull request, #21, with a similar solution, but combining both the speed from #16 and correctness of this solution.
It issues two xrandr commands to quickly disable then enable outputs, but instead of blindly disabling all connected outputs, it rearranges the configuration commands.

I believe this is outdated a bit.
