I keep getting the following error in my log at random times.
Mostly every 5-30min

I’m running a GTX 1080ti on an Asus ROG PQ278QR Monitor @144Hz
NVIDIA Driver Version: 430.40
Linux 5.2.21-1-MANJARO
Gnome Version 3.34.1

That’s no error, this always logged when something queries displays/resolutions, e.g. by calling xrandr. Do you have any Gnome-Shell plugin enabled handling displays?

Not as far at I can tell.

I have the following extensions:

Arc menu
Dash to dock
Kstatusnotifieritem
Pacman updates indicator
Removable drive menu
User themes

I had the same issue, but it was logged every second on my machine. So I told my rsyslog (on ubuntu) to ignore those messages:

$ cat /etc/rsyslog.d/40-gdm-x-session.conf 
# Stop messages that contain "NVIDIA"
:rawmsg, contains, "NVIDIA" stop

This is quick and dirty, there is probably a better way to do this.
