a full install is always an option with linux
i hate to suggest it because it can be a hassel,
but if you are worried that you errantly clicked a feature that is complicating your system,
or there is a potential for corrupt install media you can give a reinstall a try...
the more you do it the less intimidating it is
so your whoami is saying unk, meaning you are logged in as a user
linux has different permissions based on access granted to users
the root is the most powerful user, and to do a great deal of things you must utilise the root user
this protects your system from programs changing your system without your knowing and unwanted guests assuming control of your sytem
you can read up on the whys and wherefores:
the screen lock looks like a permissions issue:
is this password issue affecting your use of your system in other ways?
i've made the same mistake as unktv, and ive made the same mistake you are making now by accusing jdkaye of trying to confuse someone,
by attempting to help someone new to the community you are encouraging that person,
i hope unktv figures this out and learns to love linux and gives back to the community when thae knows what's up and and someone new has a problem thae've dealt with,
derriding jdkaye's 'senior member' status is laughable... that is just a title associated with someone who contributes a great deal to this community, i am sure jdkaye has as much control over that being displayed as my account saying 'member'...
look at jdkaye's post history: 4,122; that means jdkaye has voluntarily either helped or attempted to help people more than four thousand times, that is commendable, hardly deserving of derision
i, and jdkaye, are just trying to help unktv solve his problem?
i felt jdkaye clearly and elegantly explained the lack of information in my post to unktv
sometimes clarification is necessary,
that is a symptom of communication,
i hardly see how it would "confuse newcomers and make their life (myself included) unnecessarily difficult"
if you have a clear solution that is simple to unktv's issue i'd like to hear it
