nVidia and non-permanent dual monitor setup

JoKo · 2015-08-01 18:00:08

Hello,

I own an nVidia GeForce GTX 970 and use the binary drivers (currently 352.30) to drive my dual monitor setup. To the left there is a 1920x1200 monitor and to the right a 2560x1600 one.

nvidia-settings generated the following file:

My question is if there is a way to have only my main monitor (the right one) working sometimes. With the current configuration file, if I don't switch on the left monitor, the right one is not working properly (screen is padded due to the +1920 setting in metamodes, I suppose). I have tried setting -1920+0 and +0+0, but it is not working. Would you suggest anything else?

I'm using xrandr commands packed into an .sh script, which I just run from console as needed.
