How Install

0 - clone the repository or donwload

git clone https://github.com/ryuuzaki42/24_Bumblebee-SlackBuilds-Packages.git

Or download

https://github.com/ryuuzaki42/24_Bumblebee-SlackBuilds-Packages/archive/master.zip

1 Create group bumblebee:

su -
groupadd bumblebee

2 Add users to the group: # Change USERNAME to your user name

usermod -G bumblebee -a USERNAME

3 Install - upgrade packages

cd Bumblebee-SlackBuilds-Packages/final_packages/upgrade/
upgradepkg xf86-video-nouveau-blacklist-1.0-noarch-1.txz

cd ../install/
upgradepkg --install-new --reinstall *z

cd kernel_upgrade/
upgradepkg --install-new --reinstall *z

4 Add bumblebee to start

chmod +x /etc/rc.d/rc.bumblebeed
echo "/etc/rc.d/rc.bumblebeed start" >> /etc/rc.d/rc.local

Reboot to test

If you use slackpkg+ (http://slakfinder.org/slackpkg+.html), Set nouveau to greylist: echo "xf86-video-nouveau" >> /etc/slackpkg/greylist

After a Kernel update need to rebuilt

bbswitch
nvidia-kernel

Test - Note: you need to re-login (or rebbot) to update take effect

Run:

glxinfo | egrep "OpenGL vendor|OpenGL renderer"

Result example:

OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) HD Graphics 620 (KBL GT2)

Now test the NVidia card:

optirun glxinfo | egrep "OpenGL vendor|OpenGL renderer"

Result example:

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: NVIDIA GeForce 940MX/PCIe/SSE2

Card version of the test: GeForce 940MX

Steam run game with bumblebee video card

https://support.steampowered.com/kb_article.php?ref=6316-GJKC-7437

Try

primusrun %command%

Sometimes optirun is more stable

optirun %command%

In some cases, neither of those work (e.g. in Team Fortress 2) so I use:

LD_PRELOAD="libpthread.so.0 libGL.so.1" __GL_THREADED_OPTIMIZATIONS=1 optirun %command%

Note: due to the sync between framerate and refresh rate, you may not see any difference between primusrun and the intel card in glxgears, although you will

see drastic differences playing high end games. In the past the vblank_mode set to 0 improved framerates and helped with screen tearing, now tho this should

only be used for benchmarks or tests:

vblank_mode=0 primusrun

Errors

Error - fatal: failed to load any of the libraries .../libGL.so.1

Backup libGL.so.1

mv /usr/lib64/nvidia-bumblebee/libGL.so.1 /usr/lib64/nvidia-bumblebee/libGL.so.1.back

Create a link simbolic from libGL.so.1.7.0

ln -s /usr/lib64/nvidia-bumblebee/libGL.so.1.7.0 /usr/lib64/nvidia-bumblebee/libGL.so.1

Error: Module glx does not have a glxModuleData data object

https://github.com/WhiteWolf1776/Bumblebee-SlackBuilds/issues/51

Sometimes just need the last part, with set the card in /etc/bumblebee/xorg.conf.nvidia

Go to the modules folder:

cd /usr/lib64/nvidia-bumblebee/xorg/modules/

Backup the old version of libGLX.so.0

mv libGLX.so.0 libGLX.so.0.back

Create a link simbolic from libglxserver_nvidia.XXX from the up folder

ln ../libglxserver_nvidia.so.450.66 ./libGLX.so.0

Now the error glx not appears, but the card is not detected. Need to set manually the correctly card

See the card ID

lspci | egrep 'VGA|3D'

Uncomment the line with "BusID ..." and set the value in the last command

I my case the value is "BusID "PCI:01:00:0"

nano /etc/bumblebee/xorg.conf.nvidia
