The user that can become root (admin) is the user you created during installation. So as guest you wont be able to install new applications or modify anything in the system. You wont even be able to use the sudo command (Super User Do).

To troubleshoot your USB internet you will need to be under your user account and issue command using the sudo.

A quick fix would be if you log in to a terminal so at loggin press Ctrl+Alt+F2

Then type your user name hit enter then type your password, You wont see your password characters being typed so dont worry about it, hit enter once you are done

Then create the new user with the command (Press enter after typing each command)

Code:

sudo useradd john123 -m -s /bin/bash

Then set up a password for that user with the command

Code:

sudo passwd john123

Then add that user to some groups with the command

Code:

sudo usermod -aG adm,cdrom,sudo,dip,plugdev,lpadmin,sambashare john123

Those groups are the one your user will be able to use under that user name

reboot the computer

Code:

sudo reboot

after that and you will have that new user name at the loggin screen.

I'm, trying to log in to root, I've done the Cntl Alt F2 during boot up and when have a full UI screen.

I keep getting time outs, does seem to give me much time to type user name and password.

So when I press Enter it clears the screen and shows:

compLi5 login:

then 3 seconds later:

Quote:

[536.180016]mei_me 0000:00:03.0: reset: connect/disconnect timeout

What I would like to do is start over ( for practice ), wipe the HD clean with out damagaing or deleting basic start-up files/drivers.
I have read this as a warning:

I don't mind starting over.

Thanks
