XPS 15: Is there an option to turn off GPU in BIOS/EFI?
I'm considering a purchase of the XPS 15 9550. I will use it with Linux, though, which is not officially supported. Since several recent Laptops with NVIDIA Optimus technology had issues with Suspend (S3) I'd like to know whether there's an option in the BIOS/EFI to turn the NVIDIA GPU off altogether (or the other way around: to turn the Intel GPU off)? Can anyone with such a system take a quick look at the available options?
Or better, does anyone here already have experience with Linux on the new XPS 15 and with S3?
