Introduction

There are additional steps needed to integrate the package with optimus.

Also note that NVIDIA currently only support "outputsource" and not "offloadsink". It means that you cannot disable the dGPU (nvidia). The current workaround is to reboot onto the free Software version using an alternative grub2 boot menu.

GLVND enabled mesa

This is optional for optimus, and will enable a glvnd enabled mesa that will replace the fedora version. Once installed, it will be easier to switch between FOSS stack (nouveau) and the binary driver (nvidia). The long term plan is to have the switch enabled in fedora mesa build by default (see rhbz#1388810 ), probably by f26.

Note: Copr is not multilibs compliant, you need to copy the x86_64 repo as a new file and replace "arch" to i386, if using 32bit programs.

dnf copr enable kwizart/glvnd
dnf update

KMS for nvidia

Enable Kernel Mode Setting for nvidia-drm, this is needed for buffer sharing with the intel adapter:

grubby --update-kernel=$(uname -r) --args="nvidia-drm.modeset=1" --remove-args="video=vesa:off"

 [ -f /boot/grub2/grub.cfg ] && grub2-mkconfig -o /boot/grub2/grub.cfg

 [ -f /boot/efi/EFI/fedora/grub.cfg ] && grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Additional Configuration

For Fedora 24 and later, you still need a xorg.conf:

Please verify to Update the BusID earch GPU, specially for the nvidia device.

FAQ

  • Q: Why there is no nvidia-prime package ?
  • A: nvidia-prime is not something from NVIDIA despite the name. It's a collection of integration scripts made by canonical for Ubuntu. Best would be to avoid using custom scripts and to have the driver to setup appropriately if on optimus hardware or single GPU setup.
