Recently, I asked this question on how to solve a login loop on Ubuntu 18.04.1.
My problem seems to be specifically associated with the Ubuntu desktop environment, as I am able to successfully login using the LXDE environment. And so I thought if I could completely uninstall and then reinstall that desktop environment, I might be able to login again.
The problem is, I don't know what exactly my desktop-environment is called, or how to completely remove it. It is the default I have used ever since first installing Ubuntu, but, being a very inexperienced Linux user, I don't know what it's actually called.
Could anyone suggest a way to find out what my desktop-environment is, and how to uninstall/reinstall it?
