After adding myself as a user in User Accounts on a persistent USB install, I find it is impossible to shut down using the Shut Down command on the top panel.

Is there a way to fix this?

"sudo shutdown -h now" works, but requires opening terminal and typing a password. I am hoping for something simpler, maybe adding a desktop icon.

If you have sudo set to NOPASSWD for your user, then you can create a desktop icon containing this text:

#!/bin/bash sudo shutdown -r now

chmod +x ~/desktop/yourfile and it will do this task for you.

  • A few more questions please. Is there a simple way to create a desktop icon? Right clicking the desktop used to work, but no more. Googling, I could not find a method for my simple brain to follow. Also, is there anything like an exception list for sudo? I don't think I need a password to shut down, but would like one for things like installing software and viruses. – C.S.Cameron Feb 08 '15 at 03:59
  • Right-click ought to work. Sudo works better as an inclusion list - where you edit the sudoers file, you can explicitly permit a program (or list) to be NOPASSWD. Take a look at man sudoers - there are examples. – Mark Williams Feb 08 '15 at 08:17
  • Right clicking is still not working for me, but I have to give you credit for getting me on the right track. – C.S.Cameron Feb 08 '15 at 11:06
  • Right-click menu in an unspecified desktop manager is a whole other question! Is it Unity, Gnome, xfce, ..? – Mark Williams Feb 08 '15 at 15:28
  • ubuntu-14.04.1-desktop-i386 , Is there something I got to click to give you points? – C.S.Cameron Feb 11 '15 at 04:25
  • Plain ubuntu - probably Unity desktop then - I don't use/like it, which is why I left it as 'a different question' - seriously, pose it as a separate question! Does this look like the same thing? You did the 'points' thing already, thank you. – Mark Williams Feb 11 '15 at 14:35
