Do you mean it does not start? Or "just" that your old virtual screen feature does not work? What resolution do you get at startup? Are you able to move/resize the display correctly with xrandr? As explained earlier, the current "Virtual" line does not seem to have the exact meaning that you want. This Virtual line seems to be only meant to resize/place multiple heads in a same big screen with xrandr --pos/--above/--right-of/... From what I understood, you were moving inside your 'virtual' screen by hitting the corners with the mouse, right? I don't know how to do that today. But I also don't really see why you need this :) Brice
