[SOLVED] Downgrading nvidia-open "Failed to find module 'nvidia-uvm'"

I am having an issue with the nvidia-open 525 driver where it is causing my UI to freeze (https://github.com/NVIDIA/open-gpu-kern … issues/425) so I downgraded to 520 and this was working fine. However at some point I ran into some plymouth upgrade issues and went through a process of changing things and now I cannot seem to get the downgrade to work anymore. Well to be specific I can downgrade the package but the module doesn't show up.

Here is the command I am using to downgrade:

sudo pacman -U nvidia-open-520.56.06-11-x86_64.pkg.tar.zst nvidia-utils-520.56.06-2-x86_64.pkg.tar.zst

However when I run "lspci -k" this is what I see:

2d:00.0 VGA compatible controller: NVIDIA Corporation GA104 [GeForce RTX 3060 Ti] (rev a1)
	Subsystem: NVIDIA Corporation Device 147a
	Kernel modules: nouveau

I do have a pacman hook that automatically runs mkinitcpio and running it manually makes no difference. Installing the 525 version of the packages works fine but of course I get the freeze. Looking at journalctrl I see the following indicating a problem with the nvidia-uvm module:

$ sudo journalctl -b 0 | grep -i nvidia

Here are the nvidia packages I have installed and the kernel version:

$ pacman -Q | grep nvidia
nvidia-open 520.56.06-11
nvidia-utils 520.56.06-2

$ uname -a 
Linux gnunn-lenovo 6.0.11-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 02 Dec 2022 17:25:31 +0000 x86_64 GNU/Linux

Am I running into an incompatibility between my kernel version and the module or am I missing a step here in downgrading?

Solved, downgrading to linux-headers 6.0.10 fixed the issue. Unfortunate as I was hoping to keep getting kernel updates while waiting for nvidia to sort this out.

You want to be using dkms, then.
