Just confirming that we have all 5 machines with the Optimus video cards
running with various versions of Linux...they will run with the Optimus
turned on, but we have never been able to "see" the NVIDIA card, just the
slower on board one. With Optimus disabled in the BIOS Linux sees the NVIDIA
card and will run perfectly well with the Nouvea and NVIDIA proprietary

Please post any further findings as it is something to be aware of for us
all :-)
