I might be able to help you with the NVidia problem, although it probably isn't the answer you want to hear. I had the exact same issue with my GTX 970, along with various other issues relating to the GPU and Linux, and the only answer was to jump ship and go to team red. AMD drivers are baked into Linux and the quality shows. I'm able to play all my games at max settings with no screen tearing and no loss in FPS without proprietary drivers.I know now may not be the greatest time to buy a new card considering COVID-19, but if you can, I'd consider it The card I got is XFX's RX 5700 XT, and it was worth every penny! Just be forewarned that beast of a card is power hungry. They ask for a PSU that's at least 600W and it requires two 8 pin connectors.
NVidia dude, Linux support simply sucks. You don't have to get THAT card, I'm sure you can find something that performs as well, if not better than, the 750 Ti at a more reasonable price that openly supports Linux.Checking passmark's gpu benchmarks, the Rx 560 is very similar in performance to the 750 Ti. It's $100, but I can vouch for XFX as they make excellent quality Radeon cards, similar in quality to EVGA for NVidia cards...https://www.amazon.com/XFX-Radeon-1295MHz-Graphics-RX-560P4SFG5/dp/B072VH8NR5/ref=sr_1_5?keywords=rx+560&qid=1585710867&sr=8-5If replacing the card isn't an option, and I get it because times are pretty crappy at the moment, the only other option is removing the 750 Ti (using onboard graphics) or something software related (which I never could find and/or satisfy because NVidia can't seem to focus on the penguin).Good luck in your search!

So the 750 Ti has a 6600K. That's certainly enough. I think maybe you're seeing a difference in the xorg driver between 18x and 19x.
That's why I'm saying NVidia Linux support sucks. You shouldn't have to dig into config files and modify them, nor should you have to get a more powerful CPU. Think of how much time you've spent researching and troubleshooting. I, for one, reached a breaking point and got fed up with trying to get the performance I wanted, (we're talking years here), and I TRIED. If the software support was there, out in the open, then an NVidia card should be just as plug and playable as an AMD card without scrounging all over the internet for help.When I got my 5700 XT, I literally did a fresh copy of Ubuntu and out of the box, with NO configuring OR drivers, the card performed admirably, and still does. All my games function as they should, even Windows games at max settings! There's also the essential lack of screen tearing from every program I run, including VMs as well as Firefox.What I'm NOT saying is that NVidia cards suck, that's far from the truth. If I didn't have to search high and low while working my brain down to its last cell, I'd have stuck with my 970 providing the Linux support was there. Plus it made more sense for me to upgrade anyway as my 970 was starting to show its age while any newer titles I'll want to play would suffer from lower quality settings.CwF certainly has some good points, though. If you've got the time and determination, I'm sure you can get your 750 Ti working smoothly. At that point I'd start feeling like a developer than a user, lol. The quick and easy method, like in my case, would be to just replace the card.
