nvidia-settings 275.09.07 hangs when changing display configuration.
I frequently switch back and forth between 2 of the 3 displays I have connected to my gts450, being as I can't show all 3 at once. After logging in with the shiny new drivers installed, I proceeded to disable one of them, applied it, then tried to enable another (pioneer vsx 1020k via mini-hdmi if that's relevant) and ... nvidia-settings hangs with 100% CPU usage. If I kill it and try to launch nvidia-settings again within the same session it doesn't start at all, which strikes me as odd. I guess I'm going to have to revert to 270.41.19 for now.
