Hello,

Please provide that file content to make sure things are right.
Make sure you do not have a custom xorg.conf file lurking around, so after editing and saving /etc/X11/mhwd.d/nvidia.conf, run this command:

sudo mhwd-gpu --setmod nvidia --setxorg /etc/X11/mhwd.d/nvidia.conf

I have a GTX 960 and never gave me any troubles with the updates … but i use early kms. Did you enable it too on your install? There are two ways to enable that. Both require in /etc/default/grub to have this line:

GRUB_CMDLINE_LINUX="nvidia-drm.modeset=1"
  1. First method is to add in /etc/mkinitcpio.conf to the MODULES=() line to be like this:
MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)
  1. Second method is to use the kms in the HOOKS line … here is an example from mine:
HOOKS=(base systemd autodetect modconf kms keyboard keymap block filesystems)

Do not use both methods!
After you made the changes run:
sudo sudo mkinitcpio -P && sudo update-grub

That and a proper nvidia.conf file should give a decent desktop experience, with no flickers, no tearing.
