Recommended CLI Commands to Execute for Error Log?

[stevef]

Trying to understand the issue a bit more.

I made some changes in the display UI

What tweaks were done just before the machine froze.

Upon reboot it sent me to the infamous login loop

A description of what happens might help.

went to my system snapshots and I'm installing my first clean setup from there'

Is this using Timeshift aka System Restore Utility or DejaDup aka Backups or something else

Just a suggestion, but  after logging in to the tty via ctrl+alt+f2 maybe try the command

Code:

startx

Followed by return and post the result with any error messages
