At this point I have tried out a few things and what it looks like I am going to have to resort to is to swap out the #NVidia for something that works better with #Linux.
While Pop!_OS is a very nice OS as a desktop / casual browsing / Libre Office platform, and it seems pretty comfortable around the NVidia, the problem it has now is that it does not work with Virtual Box. Its Linux kernel version, 5.18, is one that Oracle is not yet ready to support in Virtual Box. I have too many VMs already built to throw that out and start over. And the other virtualization platforms seem to be somewhat behind even Oracle in this regard. Not one that I tried would let a VM run for more than a few minutes without glitches in teh applications on the guest.
So I need a Linux distro that will work smoothly supporting Virtual Box while also not barfing on the GPU. At this tender moment in the history of Linux and cutting-edge hardware, that sounds like no more NVidia.
