Comment 3 for bug 135353

I have the same situation. I configured my dual head as a forced 2-screen display, when one is not present at X starting but is forced to be dtetected. This way I can eg. plug in my beamer (projector) and use nvidia-settings to activate the second screen. I don't have to restart, which is a BIG advantage. Prebiously, when the beamer was not connected when X server was starting, it was able to display only 640x480 maximum resolution.

When I try to run displayconfig-gtk 0.3.2 on this configuration I get:

$ displayconfig-gtk
[]
