(Tip-toeing thru a minefield when trying to decide which laptop to buy is not much fun :-( .)
What hidden reefs am I going to strike if I buy a laptop, to install openSUSE (13.1- and beyond), which has for its graphics something called 'NVIDIA NVS 5400M Graphics with Optimus Technology'?
Will I be able to install oS on such a beast and get at least some fuzzy picture on the screen or not? (The laptop will come with Windows #8 pre-installed and which I will immediately consign to the latrine - after having it updated for free to 8.1 of course :-) .)
Anybody, please, have an answer to, comment on, the above question? There is a Bumblebee project http://en.opensuse.org/SDB:NVIDIA_Bumblebee

Definitely, You will be able to use at least one card with no big problems and performance looses. I wasn't able to get Bumblebee to work and I ended up with Intel graphic. And I'm fine. Thank you for this information.
But could you please elaborate on what you mean by, "You will be able to use at least one card with no big problems and performance looses"?
Do you mean that there are 2 cards involved in this graphic setup or that the Optimus feature can be turned off or what? Or do I need to install a new card (which one?) into this laptop which won't use the onboard NVS 5400M chip? Yes, there are two cards. Optimus technology is here to be able to switch between two graphic cards: one onboard (usually Intel, not strong, but power saving) and second (NVIDIA or ATI with high performance and higher energy consumption) very powerful. So You can choose in You need to save energy (laptop running from battery) or You need high performance (playing games or whatever). You can use kernel modules for Intel and blacklist those for NVIDIA or vice versa, so You use only the respective graphical card. It usually works fine. Bumblebee is here to give You possibility to switch graphic cards in running Linux system.

Good luck, Vojtěch
Thank you. I feel more confident now about 'NVIDIA NVS 5400M Graphics with Optimus Technology' :-) and I think I will now go ahead and order the laptop with this graphic feature.
