It is in /usr/share/libalpm/hooks/eos-nvidia-fix.hook.
It can be tested by reinstalling your nvidia driver, e.g.
sudo pacman -S nvidia-dkms
I just updated and it’s not there yet.
Installed and ready here

Did you dare to reinstall nvidia?
I just installed the hook manually since it wasn’t coming down in updates.
It is a new package, and not a dependency. So to use it you must install nvidia-hook:
sudo pacman -S nvidia-hook
Okay i did that. Now if you want me to test it i am on nvidia-dkms so to reinstall the drivers?
sudo pacman -S nvidia-dkms?
Yes, but without the question mark!

Looks like timeshift is doing something bad there.
Hopefully it is not messing with your backups.
Edit: the second try looks better.
I don’t use timeshift so I’m not sure why it caused the failure.
Maybe the scheduling of timeshift just was now?
I don’t know what this is?
/dev/dm-0
Must be something with timeshift.
I guess only @2000 could tell me if there was or is a problem but i think it is okay. I think it was running a snapshot at the time? Maybe?
Likely, but as I mentioned, I’m not using timeshift, so I don’t know much about it.
I don’t know much about it either but i have it installed on here.

We already have some threads about backup and timeshift in this forum. Maybe they provide more info about the pros and cons.
Not yet, I have just got wine working with an old game so in the middle of that. Not willing to overlap two projects ,-)

I can understand that! 
All worked here, as far as I can see, a reboot worked.
