Goal: lock down my manually-installed video driver so Ubuntu quits undoing it.

Every week or two I reboot my laptop, and each time I do, my manually-installed NVIDIA version 5.15.86.01 graphics driver gets changed, causing my external monitor to no longer work! What's the problem? How do I keep automatic updates or whatever is happening from altering my manually-installed video driver?

To manually install 5.15.86.01, I had followed my meticulously-detailed instructions here. Under the section titled "(Recommended) Option 2: download and install the driver straight from NVIDIA", see the "Install the driver" section.

I'm on Ubuntu 22.04 if that matters.

A few screenshots:

My currently-selected driver which I just chose after this last time of the manually-installed one getting undone by Ubuntu after my last reboot:

This driver seems to work okay since its version matches the manually-installed one I had previously installed. 5.15 works. 5.25 with the open kernel does not--it fails to work with external monitors (nothing displays), and it puts the laptop screen at full brightness and won't let me dim the screen.

This is not really an answer; it's a lame work-around:

I chose the 5.15 option provided by Ubuntu, and rebooted, and it seems to work just fine

From my answer here: Installed Ubuntu 22.04 and I experience frequent freezes and crashes (when using NVIDIA graphics card)
