Alex: Noob question Could you please give some instructions on how can I test this? I have 2 partitions available for testing on fresh installations. I'll be using Ubuntu (10.10 or 11.04) on a Vostro 3500 laptop, similar hardware as asus kj50 series (Intel i5 integrated graphics + nVidia 310M). And please can you instruct me on how i can report useful data on the results of these test? If not just the first part. I've tried acpi_call with a working method but with very unstable results to turn off Nvidia card.
Thanks in advance.
