Last Tuesday, I performed an software update for Ubuntu and related software. Seeing how they required a reboot, I restarted my PC and went to log back in. Only to find that I could not log back in due to being kicked back to the login screen again and again.
Here were some symptoms before I tried to attempt a few fixes.
Boot up was a bit slower than usual.
There seem to be some screen color pixelation second before booting to the login screen. I presumed this has to do with some sort of graphics driver issue, since after I tried purging the NVIDIA drivers and reinstalling some different ones, that symptom has since disappeared.
I have looked around for a couple solutions thus far, though nothing concrete in terms of results except purging the NVIDIA drivers seemed to work. While I was able to login successfully after that, it messed up the UI to the extent that it rendered it unusable.
First it changed the font to something so tiny that it was difficult to read, and it also seemed to mess with the resolution as well. Additionally, I could no longer access the UI menu at the top of the screen upon logging in. So I was forced to shutdown and reinstall the NVIDIA drivers, which brought me back to step 1.
Tried a couple other things, including updating software to see if something was missed, but to no avail. Perhaps I missed a step.
I am still a relative newbie to using Ubuntu, so any help in step by step detail would be appreciated. I will provide additional details if requested.

First two are xorgs. The last is dmesg.
