Do you have any documentation, or even random notes, on how you set that up? I have an optimus laptop and couldn't make the proprietary drivers work ( tried both rpmfusion and negativo17). I m happily using nouveau for now but at some point I ll need to use CUDA again.

I have an older Thinkpad T440p with Geforce GT 730M running Fedora 29. I use the MATE desktop rather than GNOME. I just installed the akmod-nvidia packages from rpmfusion which also pulls in xorg-x11-drv-nvidia and xorg-x11-drv-nvidia-cuda. Search for "PRIME" discussions in the README.txt under /usr/share/doc/xorg-x11-drv-nvidia. I cannot be sure every bit of my config is still necessary, as I left it alone once I got it working. First, I have /etc/X11/xorg.conf.d/nvidia-prime.conf with a small amount of config: Section "Module" Load "modesetting" EndSection Section "Device" Identifier "nvidia" Driver "nvidia" Option "AllowEmptyInitialConfiguration" EndSection Then, I created a custom script in /etc/lightdm/display_setup.sh: #!/bin/sh if rpm -q xorg-x11-drv-nvidia \ && lsmod | grep '^nvidia' ' then xrandr --setprovideroutputsource modesetting NVIDIA-0 xrandr --auto xrandr --output eDP-1-1 --set "PRIME Synchronization" 1 fi And in my /etc/lightdm/lightdm.conf I added one line to call that script: ... [Seat:*] ... display-setup-script=/etc/lightdm/display_setup.sh To be honest, my old GPU is too slow and with too small RAM to be worthwhile for OpenCL. I find it more practical to just use the Intel OpenCL runtime for multi-core CPUs on this old quad-core laptop or on newer workstations. I do get some use out of xorg-x11-drv-nvidia-cuda on a Titan X desktop GPU though.

  Thanks a lot! I 've already created a thread about my problems in askfedora, made a last post there now linking to your post here in case they help somebody else. https://ask.fedoraproject.org/t/black-screen-after-installing-negativo17-nvidia-drivers-on-optimus-laptop/1967/8?u=iolaum https://ask.fedoraproject.org/t/black-screen-after-installin... I 'll try your notes when I have enough free time to re-install if things go bad.
