This is a modified version of the x11/nvidia-driver that works with Nvidia optimus (muxless) laptops. This package also provides utilities to make it easier to run programs on the Nvidia GPU.
You can install this in 2 ways, one way is to grab the binaries from releases. and then install using pkg:
pkg install nvidia-optimus-driver-430.34.txz
or
pkg install nvidia-optimus-driver-390-390.116.txz
Please note these binaries are built on FreeBSD 12.
To build this on your system, you should clone this repo (or download the source) then do:
make install
or
make package
and then install using pkg.
To use Nvidia optimus driver, you need to start the optimus service. To do that, you can add
optimus_enable="YES"
to /etc/rc.conf
Alternatively you can do
service optimus onestart
The optimus service provides a few configurable options:
optimus_manage_kld: allow optimus to manage kldload/unload of
the Nvidia kernel modules (default="YES")
optimus_modeset: load Nvidia modeset kernel driver
(default="YES")
optimus_screen: Screen number for running the optimus X
server (default="8")
optimus_x_conf: Config file to use for X. If this doesn't
exist it will be generated automatically.
You should probably check the PCI address
specified in the generated config file as
it is extracted from pciconf automatically.
(default="/usr/local/etc/X11/optimus.x.conf")
optimus_x_flags: optimus X server flags
(default="-sharevts -noreset")
If you don't want optimus manage your kldload/unloads, you must load nvidia.ko and/or nvidia-modeset.ko yourself. Refer to x11/nvidia-driver for more info about this.
After you have the service running, you can use the provided optirun command to run your programs on the Nvidia GPU:
optirun glxgears
React
Typescript
Django
Laravel
Facebook
Microsoft
Google
Alibaba
D3
Tencent
