Nvidia Driver Not Loading and Second Monitor Issues

You should be able to get the nvidia drivers to work again. Downgrading them ought to trigger the dkms rebuild. Just downgrading the kernel was not enough it left the 530 drivers in place.

Essentially I used downgrade to roll the kernel back to 6.2.13-arch1 with:

downgrade linux linux-headers linux-api-headers

(for linux-api-headers, I went with version 6.1.9-1: there was no 6.2.13-arch1 version)

To downgrade the nvidia drivers, I used the same process reported here: Second Monitor Lags After Update - #3 by Nfox18212
