I've learned how to use ctrl+alt+F2 to come into command line but fail to know how do I live up to being a root admin so I have permission to shutdown from command. It fails from GUI every time.
I did a successful reboot after failing to give login and psw for root three times and suddely the system allowed me to write sudo reboot and that one worked successfully.
So now I need to test sudo shutdown does it need anytying more like .H or what ever for us newbies unknown things?
what login name and psw is there for the admin?is it same us for user when I log in? I tried that one three times and it failed.
I fail to use the sudo it ask me to give login and password and don't accept the username and psw that the GUI login to Ubuntu accept so easily After servaral failing it took my sudo shutdown -h now but failed to power off. But the hard reboot didn't destoy my files and I was able to start windown again.
What to do next?
