After = all its a software issue. It works well on Windows 7 without any BIOS chang= e. I'm afraid that nVidia has publicly stated that they will not be providing support for "Optimus" in their open-source drivers. There is an effort underway to reverse-engineer the "Optimus" hybrid stuff and write a driver for X, but I would not hold my breath. The big issue is that, while Optimus uses the GPUs that are supported in their binary blobs, the "Optimus" implementation uses the frame buffers in the Intel graphics, so is quite different to actually use or program for. --=20 R.
