Ubuntu not running installed nvidia driver

Hello newish to linux and this site.

I have scoured the internet in search for an answer tried many different solutions, but I have come up empty handed and at a total loss your help is much appreciated thank you. My computer is and old HP XW6400 workstation with a gtx1050ti with Ubuntu OS 20.04 nvidia driver 450 installed. But it only runs on integrated graphics. I cannot get the system to run on the dedicated graphics card,Also a funny thing is I have my hdmi cable to a tv coming from the dedicated gpu which does display everything but without sound but it says its running on integrated graphics? I do not have a secure boot option in my bios, sorry Im a greenhorn when it comes to linux.

Also the nvidia x server settings app opens to a blank screen. I have installed the latest Ubuntu OS 20.04 Nvidia 450 driver, after trying Ubuntu 20.10 Nvidia 455 driver version with the same issues.

dwill63@dwill63:~$ nvidia-settings

ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

(nvidia-settings:93443): GLib-GObject-CRITICAL **: 00:28:52.427: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 00:28:52.432: PRIME: No offloading required. Abort
** Message: 00:28:52.432: PRIME: is it supported? no

I have issues where my gpu driver is not running or being seen I get multiple errors trying to run different commands in the CLI like

dwill63@dwill63:~$ nvidia-smi

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

It shows the nvidia-driver-450 is installed and chosen in the additional drivers tab.
