Can you explain a bit more what you did? I understand that you use ScreenCount() to avoid useless tests. But you're only testing the NV-CONTROL extension on :X, not on each :X.Y. Is it guaranteed that :0.0, :0.1 ... support the same list of extensions? Isn't it possible to have a single X server with a NVIDIA board driving :0.0 and a non-NVIDIA board driving :0.1 ? By the way, please try to not reindent the code next time, it makes the patch much harder to read :/ (your editor may be doing it in your back) Brice
