Hybrid graphics

This page currently has some details about NVIDIA and Intel and Hybrid graphics using them.

I was running a setup where:


 * My display is connected to the Intel chip physically.
 * There is no hardware multiplexer available (and therefore no BIOS option to switch to one of the cards)
 * NVIDIA and Intel cards are the two graphic cards on this laptop.

You have several options at your disposal:


 * 1) Use Optimus: Official NVIDIA DRiver (blob) and Intel driver : https://wiki.gentoo.org/wiki/NVIDIA/Optimus
 * 2) Use bumblebee: OFficial NVIDIA Driver(blob) and Intel driver : https://github.com/Bumblebee-Project/bumblebee-gentoo/
 * 3) When running bumblebee, you have two options of using either optirun or primusrun (PRIMUS is NOT PRIME, they are different.)
 * 4) Using nouveau and Intel with bumblebee, I couldn't set it up.
 * 5) Installing PRIMUSRUN without nvidia-drivers was seemingly impossible because it kept trying to pull it.
 * 6) Use PRIME: Open Source NVIDIA Driver (nouveau) and Intel driver: http://nouveau.freedesktop.org/wiki/Optimus/
 * 7) When running this setup with PRIME, DRI2 and DRI3 are two options.
 * 8) According to some threads floating around, NVIDIA official driver has better performance than Nouveau.
 * 9) Although nouveau is considered slower than NVIDIA, nouveau + prime + DRI3 was the only option that worked for me.

Some pages that may be useful in order to install the NVIDIA official drivers or the nouveau driver:
