Cannot boot on Fedora 36 (510.68.02 driver). "Failed to start nvidia-powerd.service"

System: GTX 3070ti (FE), Ryzen 5600x, 32GB RAM, 2560x1440@170Hz (desktop system)
Output of UNTITLED - Pastebin Service
Driver version: 510.68.02 from RPM Fusion repositories
Distro: Fedora 36 (clean install)

I tried to install the proprietary driver from RPM Fusion but it causes boot to hang with the error message “Failed to start nvidia-powerd.service”.

I don’t think that it is a wayland or X server issue - it comes before it in the boot process and I tried to troubleshoot it by booting to the text console with the same results.

This system previously ran fine on Fedora 35 and X server is useable with the nouveau driver.

The only similar issue that I can find on google is this /r/Fedora/comments/unfbel/fedora_36_akmodnvidia_driver/
(sorry, the forum only allows me to put in one link!)

Thanks for your help in advance!

There are no nvidia modules available. Please try reinstalling kernel headers and driver.

Thanks generix.

I’ve already tried this unfortunately. I did a second clean install of Fedora 36 and installed the driver with the same result. I also tried uninstalling the driver and reinstalling with the same result.

I ran the various debug commands using nouveau since I couldn’t boot using the proprietary driver. Is that maybe why it’s showing the modules as unavailable?

For reference, I used the instructions here: Howto/NVIDIA - RPM Fusion I made sure that I was on the latest kernel and rebooted prior to doing the installation as per instructions. I also let the computer sit for 15 mins and checked htop that there were no processes running to ensure that it had fully built.

For anyone else searching, it looks like a known issue. More info here: Black login screen when nvidia v470.103.01 drivers are installed on fedora 36 fresh install - #7 by dragontome

I have this trouble on my Fedora 36

If I restart the service, my Fedora back to work

So I do systemctl stop nvidia-powerd.service ;
sudo dnf reinstall xorg-x11-drv-nvidia-cuda-3:515.57.-1.fc36.*
systemctl start nvidia-powerd.service
