Yes, although mux-less optimus laptops are by far the more common scenario, so option 2 is unavailable for many users, and we don't particularly care about option 1 since the user wouldn't install the nvidia packages in that case. > + Ignore this message if you have a laptop with NVIDIA Optimus technology > + (dual Intel and NVIDIA GPUs). > > Or can we somehow detect Optimus systems and show an entirely different > template there? Ack, probably a better idea than just assuming the user knows how to determine if their laptop uses optimus or not. How Canonical does this in their nvidia-prime package can be found at [1], which requires nothing more than lspci (not sure if we can just assume pciutils is available). I guess we could check for optimus systems in a similar manner somewhere in postinst, and then just avoid triggering the nvidia-support/create-nvidia-conf template?
