Install Dependencies<\/strong><\/p>\n

#yum install -y libbsd-devel libbsd glibc-devel libX11-devel help2man autoconf git tar glib2 glib2-devel kernel-devel kernel-headers automake gcc gtk2-devel<\/p>\n

You also need to install VirtualGL. Download the latest version for your arch at the VirtualGL download page or use yum command<\/p>\n

#yum install VirtualGL <\/p>\n

If you want to run 32 bit apps on your 64 bit system, then also install:<\/p>\n

#yum install VirtualGL.i686 <\/p>\n

Install Bumblebee<\/strong><\/p>\n

Install the Bumblebee yum repository
\nFedora 21<\/p>\n

$yum install http:\/\/install.linux.ncsu.edu\/pub\/yum\/itecs\/public\/bumblebee\/fedora21\/noarch\/bumblebee-release-1.2-1.noarch.rpm<\/p>\n

Install Bumblebee:<\/p>\n

$yum install bbswitch bumblebee<\/p>\n

Bumblebee with the NVIDIA proprietary drivers<\/p>\n

The previous commands install bumbleblee with the nouveau drivers. If you want to install bumblebee with the NVIDIA proprietary drivers you must also follow these instructions:<\/p>\n

Install the bumblebee-nonfree repository:
\nFedora 21<\/p>\n

$yum install http:\/\/install.linux.ncsu.edu\/pub\/yum\/itecs\/public\/bumblebee-nonfree\/fedora21\/noarch\/bumblebee-nonfree-release-1.2-1.noarch.rpm<\/p>\n

For all versions<\/p>\n

Make sure you have glibc-devel installed because it is needed for bumblebee-nvidia to compile the driver<\/p>\n

sudo yum install glibc-devel<\/p>\n

Now install bumblebee-nvidia<\/p>\n

#yum -y install bumblebee-nvidia<\/p>\n

“bumblebee-nvidia” is both a rpm package and a shell script. The “bumblebee-nvidia” package contains the shell “wrapper” script, init scripts to run it at bootup, and a SELinux security policy, and lastly a copy of the NVidia Linux binary driver “blob” downloaded from NVidia’s UNIX drivers page. This is why the packages are so large compared to the bumblebee package.<\/p>\n

Reboot.<\/p>\n

Testing Bumblebee<\/strong><\/p>\n

To verify you are now using the NVIDIA driver, run the glxgears demo (from mesa-demos):<\/p>\n

optirun glxgears -info | grep “GL_VENDOR”<\/p>\n

You should see some gears rotating. In the terminal you should see “GL_VENDOR = NVIDIA Corporation” or something similar.
\nPrimus<\/p>\n

For speed imrovements you can use primus. Primus is a shared library that provides OpenGL and GLX APIs and implements low-overhead local-only client-side OpenGL offloading via GLX forking, similar to VirtualGL. It intercepts GLX calls and redirects GL rendering to a secondary X display, presumably driven by a faster GPU. On swapping buffers, rendered contents are read back using a PBO and copied onto the drawable it was supposed to be rendered on in the first place. Currently primus requires the NVIDIA proprietary drivers.<\/p>\n

Install primus:<\/p>\n

#yum -y install primus <\/p>\n

If you want to run 32 bit apps on your 64 bit system, then also install:<\/p>\n

#yum -y install primus.i686<\/p>\n

Testing primus<\/strong><\/p>\n

Open up a terminal and run:<\/p>\n

PRIMUS_VERBOSE=2 optirun -b primus glxgears -info<\/p>\n

If primus is working properly, you should see “primus: profiling:” messages every so often in the terminal you ran it from.
\nHow to use Bumblebee<\/p>\n

General Usage:<\/p>\n

optirun [options] [application-parameters]<\/p>\n

If you installed primus, then you can use the following command to take advantage of it:<\/p>\n

optirun -b primus [application-parameters]<\/p>\n

Start Windows applications:<\/p>\n

optirun wine .exe<\/p>\n

with primus:<\/p>\n

optirun -b primus wine .exe<\/p>\n

By default, primus renders up to 60 fps. To render more frames per second:<\/p>\n

vblank_mode=0 optirun -b primus [application-parameters]<\/p>\n

In practice this will probably only waste power, as most screens do not display more than 60 frames per second.<\/p>\n

You can always run “man optirun” for more information. <\/p>\n

Optimus and Steam for Linux<\/strong><\/p>\n

To make a game run using the discrete GPU, use these simple steps:
\n1. Select a game – that you want to run using your discrete Nvidia card – from the Library page of the Steam client, right-click, and select Properties.
\n2. Click the SET LAUNCH OPTIONS… button and specify primusrun %command% for the command line.
\n3. Save your changes.This method allows you to pick when the discrete NVidia GPU should be used on a per-game basis.<\/p>\n
