i have 2 monitors,

the left one is my "main" monitor with 1920x1080_120, the right one my second with 1680x1050_60. (i have a nvidia card setup with twinview)

when i play a game or something in fullscreen mode, the full resolution is used in fullscreen (monitor 1 + monitor 2).

i read something about the metanodes i can use to shut down the one monitor that i dont need durning a "fullscreen session".

i used the following:

Option         "metamodes" "DFP-0: 1920x1080_120 +0+0, DFP-2: 1680x1050_60 +1920+0; DFP: 1920x1080_120 +0+0, NULL"

Its working great, the second (right) monitor is shutting down when i press "CTRL ALT +" and is starting agin when i press the same keystroke.

But in the second mode when the second monitor is "down", i got the full "monitor 1 + monitor 2" resolution on my first (left) monitor, i can move my mouse to the right to see the contents of the second monitor and move it again to the left to the what is normally seen on the first monitor. Its something sliding between the 2 monitors on one display.

How can i avoid this?
