Any thoughts on how to reinstall the current nVidia driver?

Moderator edit: Fixed formatting for readability

It appears you need to update to the NVIDIA 580xx series.

Done ...

Looks like I can’t update the driver, any ideas?

Since MHWD doesn’t know about the 575xx series anymore and nothing was done to mitigate issues like this (sorry, not my department), you’ll have to manually remove the related packages first.

First check what NVIDIA packages you have installed with:

pacman -Qs nvidia

All the packages with 575xx in the name can be removed with the following command in order to yank them out without anything complaining:

sudo pacman -Rdd <package names here>

Then use MHWD again to install the current drivers:

sudo mhwd -a pci nonfree 0300

Make sure you do the above all at once and do not reboot until the drivers are successfully installed.

Followed the recommendations listed in the last post. No luck, ran into other issues. Unfortunately, I did not copy the these before rebooting. Reboot failed with black screen. I have reinstalled by backup image and all is fine. I will try again, this time I will copy the final error comments before rebooting. The best I can remember is some problem with MPV (not sure about MPV) library mismatch, still slowing 575xx not matching 595.xx
