I'm currently using a live USB session.
I was watching some TV (Plex) and using Firefox. I installed some software an hour or so ago (audacity) with no problems using paman. I ran an update in terminal - using my password which is very easy to type and remember.
However, a little later I tried to install 'cmatrix'. The terminal refused my password.
I switched to a tty, it refused my login.
I tried a reboot - I was greeted with a default cursor and black screen - switching to tty I was also unable to login.
Is this issue affected by my setting the desktop to auto-login? How can I fix it?
