Hej,

I'm using a laptop with an external screen connected to the VGA port at home (extended desktop, monitor next to Laptop-Screen). When I take my laptop to work, I usually get it into suspension mode and carry it away. So when I fire up my laptop at work again my screen is still as big as if the external monitor was still connected. I just get the popup saying me that the external monitor has been disconnected, if I want to reconfigure my screen. Sure I want that. The only problem with that: Since the monitor is not connected anymore, I can't select the mode for it and thus I can't disable it. A command line xrandr command does the job here, of course...
If I think about that in advance, so if I disable the external monitor back home before I disconnect it, I still get the popup when I disconnect the monitor and I just think: "Come on, I just disabled it!"

My suggestion to this "problem": There is already a standard configuration applied when booting up with the external monitor connected. Maybe one could extend this one to be applied whenever an external monitor is connected (maybe one could ask me first, as well) and then automatically disable it, when it gets disconnected. As I see it, the technical basics are all implemented, already, there would just an additional button in the popup dialog so that there is "configure", "ignore" and "default screen".

What do you think about this suggestion?

Cheers
Felix
