Bumblebee is an effort to make NVIDIA Optimus enabled laptops work in
GNU/Linux systems. These laptops are built in such a way that the NVIDIA
graphics card can be used on demand so that battery life is improved and
temperature is kept low.

It disables the discrete graphics card if no client is detected, and start
an X server making use of NVIDIA card if requested then let software GL
implementations (such as VirtualGL or primus) copy frames to the visible
display that runs on the integrated graphics.

This package only provides features for using the proprietary nvidia drivers.
Users of the libre nouveau driver should prefer using DRI PRIME over

This package provides Bumblebee configuration files and binaries built
against the nvidia390 driver for GeForce 420 and later cards.
