Diff for "Howto/Optimus"

Differences between revisions 1 and 5 (spanning 4 versions)

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)

!!! BIG FAT WARNING - This is still experimental documentation, only experimented users should follow.

GLVND enabled mesa

This will enable a version glvnd enabled mesa that will replace the fedora version.

Note: Copr is not multilib 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

Fedora 25

Not yet supported because xorg-server ABI but it should be simpler.

Fedora 24

For Fedora 24, you still need a (complicated) xorg.conf:

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