Unable to use Optimus Manager

Similar to - https://bbs.archlinux.org/viewtopic.php?id=255752

I used to switch between Nvidia GPU and AMD GPU using optimus-manager

After I updated all packages yesterday, I am no longer able to boot into Nvidia and Optimus Manager does not work as well.

Whenever I try to use Optimus manager (using a command like - optimus-manager --switch nvidia or optimus-manager --print-mode), I get the following error logs -

ERROR: the latest GPU setup attempt failed at Xorg pre-start hook.
Log at /var/log/optimus-manager/switch/switch-20220824T143825.log
Cannot execute command because of previous errors.

The contents of /var/log/optimus-manager/switch/switch-20220824T143825.log are -

The above exception was the direct cause of the following exception:

Looking at the logs, I tried modprobe nvidia and got the error - modprobe: ERROR: could not insert 'nvidia': Invalid argument

The contents of optimus-manager.conf are - https://pastebin.com/UK0AUnri
Display manager - sddm
I have tried playing around with prime-offload and prime-switch but to no avail.
How can I fix this?

Re: Unable to use Optimus Manager

pacman -Syu tells me that there are no packages to be updated.

Re: Unable to use Optimus Manager

Ok, that's the good one.
Did you rebuild the dkms packages after installing this version ~4h ago?

Re: Unable to use Optimus Manager

Oh.. I think I did not. How do I rebuild all my dkms packages?
Or by rebuild do you just mean reinstall all the packages with dkms in the name?

Re: Unable to use Optimus Manager

sudo dkms autoinstall did not do anything

Re: Unable to use Optimus Manager

# dkms build nvidia/515.65
# dkms install nvidia/515.65

Module nvidia/515.65.01 already built for kernel 5.15.62-1-lts (x86_64).

Module nvidia/515.65.01 already installed on kernel 5.15.62-1-lts (x86_64).

Don't think it did anything.

Do I need to remove it first using dkms remove nvidia/515.65.01?
