Ubuntu20.04 NVIDIA 470 driver is not loaded

@ ubuntu 20.04
kernel 5.11.0-34-generic
I have had a couple of problems with the graphics since I installed the system. Right after the install apt autoremove wanted to delete my nvidia driver. I marked it as manual and all was well. Now after the latest security update my driver does not load:

$ nvidia-settings

ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

(nvidia-settings:9594): GLib-GObject-CRITICAL **: 11:39:29.529: g_object_unref: assertion ‘G_IS_OBJECT (object)’ failed
** Message: 11:39:29.531: PRIME: No offloading required. Abort
** Message: 11:39:29.531: PRIME: is it supported? no

So now I was thinking of looking at the problem a little closer. currently I have 768p resolution on a 4k screen and can not change it. I have reinstalled the nvidia 470 driver by following this post on nixcraft

  1. Boot Ubuntu into a single user mode/recovery mode by following https://wiki.ubuntu.com/RecoveryMode
  2. Search for Nvidia driver, run:
    apt search nvidia-driver
  3. Reinstall Nvidia driver:
    sudo apt reinstall nvidia-driver-470
  4. Reboot the system.

and followed the instructions in this post:

but it did not help. I also created a blacklist file /etc/modprobe.d/nvidia-blacklist.conf with:

blacklist nvidiafb
blacklist nouveau

I attach the bug report:
