If you want to check your Xauthority permissions, do this: ls -lA
There are 2 possible sources of failure here:
(with Alt+arrow keys, you can switch between screens: Login, command line, etc.). So now, Press Ctrl+F3 to get back control over your command line. If you cannot log in to your account but the GUI is back, you have to fix your drivers from the command line (you broke them in step 1!!!)

(Used up the majority of CPU in my case). If Xorg is selected (The third option in the screenshot), it’s probably not the best. You can see that in your Software updates application under “Additional Drivers”. This is probably because Ubuntu defaults to the XOrg drivers with a new Installation. I decided to document it once and for all, for everybody suffering from new installations of Ubuntu like me. In the process of fixing these errors, I went through the all-too-familiar NVIDIA, light-dm issues that I had to go through a couple of times as a Ubuntu newbie. The trouble came afterward when the installation was suuuuper slow. Having had enough of Kubuntu, I switched to Ubuntu 20.04, which wasn’t all so much a pain to install, you know… the GUI support, and all. I recently noticed that I haven’t used my Kubuntu PC in a while during which it gathered dust. I switch between Windows and Flavors of Ubuntu a lot.
