With Lenovo anyway, there is a BIOS setting to select the graphics card you want to use, with Auto / Optimus the default. Change to PCI / External for the nVidia card or Internal for Intel, and it works fine for SL6.x...

Subject: Re: SL on Dell Precision M4800 Mobile Workstation
Hi,
i, for one, would approach any laptop using Nvidia Optimus technology with caution, particularly if i want to run Linux on it.
I googled your laptop config and it comes with 'Intel(r) Core(tm) i7-4900MQ Processor' meaning Intel(r) HD Graphics 4600 built in.
I just wander, why the laptop sellers stopped to announce Nvidia Optimus technology on their laptops - nowadays noone says a word. Is it because it got a bad rep? In my eyes it indeed does.
Bumblebee is working solution on Linux, but not entirely convenient? - you need to switch between VGAs manually as far as i understand the problem.
I don't have personal experience with Optimus, as i do not own any newer built laptop (my own is 6yrs old).
But after reading many many angry threads on various linux (and even a
windows) forums, i'd think twice before buying one.
