Blender 4.0 is not recognizing CUDA. (Downloaded from blender.org)

I have installed Nvidia driver using HowToNvidia and HowToCUDA.

Is this issue related to kernel or due to Nvidia driver update?

I tried to check by booting with old kernel version, nvidia failed and throw driver mismatch error.

For me the update to the 545 driver also broke cuda since cuda was updated from 12.2 to 12.3.

I fixed it on my system by downgrading back to the 535 driver.

sudo dnf remove \*nvidia\*545\*
sudo dnf install akmod-nvidia-535.129.03* xorg-x11-drv-nvidia-cuda-535.129.03 nvidia-{settings,persistenced}-535.129.03

Note that this will only replace the kmod-nvidia package for those kernels where the 545 driver is already installed. You can see which driver is installed for all kernels with dnf list installed kmod-nvidia-\*

I am unsure if the install of the 535 drivers will work if you are using the rpmfusion-nonfree-nvidia-drivers repo since I do not use that repo. It worked for me with the rpmfusion-nonfree repo.

Thankyou so much for solution :heart:. Will try and update here.
