BIG FAT WARNING - This is still experimental documentation, only experimented users should follow. I hightly recommands to have another PC == 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 }}} |

Introduction
With Fedora 25 and later, Optimus devices are automatically detected.
This Howto is a subset of the main documentation, please read the Howto NVIDIA first.
Known limitation
Please 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 boot option menu.
Proprietary/FLOSS switch
At this time, this can be done by manually removing "rd.driver.blacklist=nouveau modprobe.blacklist=nouveau" from the grub2 cmdline. The plan is to have a grub2 menu to have the choice. Please see Bugzilla [RFE] Switcher for Xorg nvidia/FOSS config
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.
