I think I have a very recent version of the driver (as I updated to the last kubuntu release 9.10 karmic koala and I maintain it up-to-date quite often). In fact I wonder if some thing changed in the new Intel's driver. Indeed, before I upgraded ubuntu, I could run pythonOcc without any problem of such kind. Maybe I just need to recompile OpenCascade (but this would be quite unconvenient if I have to do this each time I update the Intels driver and anyway it does not make much sens to me). I'll check when back home.
