Nvidia settings not sticking on reboot

Hi, I’ve just installed Pop_os on my desktop after using it on my laptop for a few months. My issue is that my Nvidia settings are not sticking after I reboot. I’m using Nvidia setting because I’m using custom resolutions for my side monitors. They are 1920x1080, and my main monitor is 3440x1440, so in order for everything to look good I always run them at 2560x1440 in windows. I can manage to get the monitors to run at 2560x1440 trough the Nvidia settings. I start by opening nvidia-settings with sudo, then change settings as desired, and save it as /etc/X11/xorg.conf.d/20-nvidia.conf.

However it wont stick on reboot, I have also tried to follow this.

I’m running driver version 435.21

This is my 20-nvidia.conf:

Are there any other files in /etc/X11/xorg.conf.d/? Does /etc/X11/xorg.conf still exist? If so, those other files may be overriding the NVIDIA settings.

It would also be helpful to post the Xorg logs from /var/logs/ (I forget the exact layout/filename. Generally you should always make logs available when asking for help :slight_smile:

Good luck.
