[SOLVED] API Mismatch causes Nvidia Driver fail

In Xorg.0.log, i get

NVIDIA: Failed to initialize the nvidia kernel module.

In journalctl, i get

NVRM: API Mismatch: the client has the version 455.45.01, but
NVRM: this kernle module has the version 455.38. Please
NVRM: make sure that this kernel modula and all NVIDIA driver
NVRM: components have the same version.

I'm stumped on this one.
Should I give up and use Nouveau?

Did you start/restart the X server since the 455.45 package installation without rebooting?

I believe so, but I also tried rebooting after I noticed the problem.

My video is running off my CPU right now so it's slow, but I can find additional info if you need.

Re: [SOLVED] API Mismatch causes Nvidia Driver fail

Another thing that's part of this weird issue is when I go to remake my initramfs, there's now possibly missing firmware for

xchi_pci

which was not missing before.
This is probably the graphics card PCI connection.

The card isn't dead though.
I booted into windows and ran a video game and everything functions normally.

Re: [SOLVED] API Mismatch causes Nvidia Driver fail

What is the output of the following:

modinfo nvidia
uname -a
pacman -Q linux

and what package provides the nvidia module?

SOLUTION:

I solved this with:

$ sudo pacman -Rdds nvidia
$ sudo mkinitcpio -P
$ reboot

$ sudo pacman -S nvidia
$ sudo mkinitcpio -P
$ reboot
