After upgrading from ubuntu 16.04 all the way to ubuntu 18.04 im seeing a lot of messeges like this during apt-get upgrade.

/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/nvidia_settings.conf

update-initramfs: Generating /boot/initrd.img-4.15.0-29-generic

/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/nvidia_settings.conf: No such file or directory

Sometimes my nvidia driver loads, simetimes it does not.
I'm currently using the ppa:graphics-drivers/ppa.
I've tried purging nvidia several times.
Would like to not have to fresh install.
It looks like the problem is that symbolic link for nvidia_settings_conf is going nowhere, but I'm not sure where it is supposed to be.

Output nvidia-smi

I had a similar warning after upgrading from 16.04 to 18.04

I have removed nvidia-settings.conf from /etc/ld.so.conf.d since it was pointing to files which did not exist. So far so good...

server:/etc/ld.so.conf.d$ sudo mv nvidia_settings.conf OLD_nvidia_settings.conf_OLD

Link of this file to /etc/alternatives/nvidia_settings.conf was broken, rename to OLD_nvidia_settings.conf_OLD in /etc/ld.so.conf.d as you don't know if something is looking for a file starting with nvidia_settings....
