Ever since I started posting about this, I've been receiving lots of suggestions from the Linux Mint community. I've also been discussing this with TOS, and Joe Collins. I'm probably going to end up removing the nvidia card and just use the onboard skylake graphics until I might buy an AMD card replacement. There is one thing that I haven't tried yet. Going directly to nvidia's website, downloading the run file and installing that way.
I tried adjusting so many different things, that I'm not sure I can remember them all. I checked for screen tearing, and that was fine. I messed around with all the nvidia settings, one by one. None of them made any difference.
I will share with you guys something very weird. POP OS 20.04 works with the nvidia card, right out the box! That is, until you need to update chromium. The original chromium browser for POP OS is a deb package. But the replacement is a flatpak. The flatpak makes it get all jumpy again.
When I was trying out POP OS! I thought I found a solution. I looked at the specs and decided to try configuring Linux Mint in much the same way. I updated the kernel from 5.4 to 5.11 kinda like POP is running. It made absolutely no difference. So far the only solution that has worked for me, is use a fresh install of Linux Mint XFCE and just run the skylake graphics. The reason for the fresh install, is because something weird happened to my main install. I think the nvidia driver on the system causes the skylake graphics to screen tear when they wouldn't normally. Whenever I test the skylake graphics out on a Linux Mint XFCE Live disc or just make a new install to a test drive the screen tearing on the skylake just magically goes away. Also the skylake doesn't jitter like the nvidia is.
