Ran basic kernel update via built-in updates this morning.

Now my NVidia 1660 is not recognized.

Tried to install nvidia drivers again using:

$ sudo ubuntu-drivers autoinstall

That fails with erros which look like:

Traceback (most recent call last):

  File "/usr/bin/ubuntu-drivers", line 513, in <module>

    greet()

  File "/usr/lib/python3/dist-packages/click/core.py", line 1128, in __call__

    return self.main(*args, **kwargs)

  File "/usr/lib/python3/dist-packages/click/core.py", line 1053, in main

    rv = self.invoke(ctx)

    return __callback(*args, **kwargs)

  File "/usr/lib/python3/dist-packages/click/decorators.py", line 84, in new_func

Now, the graphics show up like:

llvmpipe (LLVM 13.0.1, 256 bits)

Only 1 of my 2 monitors works and my display is at 1024x768.

Have no idea what to do.

Update

I just found this but it seems to be a false positive.

I attempted to run the NVidia provided .run file to install and saw this:

I believe the important part is :

ERROR: Unable to find the kernel source tree for the currently running
kernel.

Then i tried switching in the panel and saw this:

This must be happening to someone else, also, right?

I have installed the kernel headers in an attempt to get the NVidia drivers to work:

sudo apt-get install linux-headers-$(uname -r)

I'm now downloading Ubuntu 22.04 iso, imaging a USB stick and going to see if I can repair the installation.

So there is no "repair" option but when I run the USB stick version I get both monitors back and at a valid (high) resolution.

This is ridiculous. All because I accepted a kernel update from the official updates. Oy!

Definitive Answer

I had to install Ubuntu 22.04.1 LTS again. I was very lucky because I had just done a complete backup of my system yesterday. Phew...Very lucky.

Beware!

I've always immediately installed kernel updates. I will now wait to install them if I am able.

Restore Previous Kernel

I also attempted to restore the previous kernel.
Here is a snapshot of the choices I had:

I tried each one, but none of them got me back to a good place.
Even after trying each one I still only had 1 screen & it was stuck at 1024x768.

I just started my computer up & it is back to 1 screen & 1024x768.
I really dislike Ubuntu now. Would this happen on Mint?
