Get a tty console (ctrl+alt+F2) then run 'startx' and 'journalctl -b' to know about errors

I ran the commands you requested in tty. startx gave me a blank screen for some time and then came back with the screen in the attachment. The second command came back with 2007 lines of what is to me jibberish. Not sure if that created a log file somewhere i can upload or what to do next. If anyone else has any ideas im all ears!
edit: oops sorry forgot to attach the screenshot
