[SOLVED] Ubuntu w/ Openbox -- shutdown doesn't work properly

[chriswadams]

I've recently installed Ubuntu's 12.04 mini.iso with Openbox and Simple Login Manager, on an Acer Aspire One netbook. I want to be able to shutdown and restart from the Openbox menu, but I can't get it to work. There are a number of threads with solutions to similar problems over on the Ubuntu Forums, but none of them has worked for me. Note that I can shutdown with the terminal command '$sudo shutdown -h now'.

Here is the XML I have in my 'menu.rc' file:

Code: Select all

<item label="Restart">
    <action name="Execute">
       <prompt>Are you sure you want to Restart?</prompt>
       <command>sudo shutdown -r now</command>
    </action>
  </item>  <item label="Shutdown">
    <action name="Execute">
    <prompt>Are you sure you want to Shutdown?</prompt>
       <execute>sudo shutdown -h now</execute>
    </action>

In place of the command 'sudo shutdown -h now', I have used 'sudo /sbin/shutdown -h now', 'sudo /sbin/halt', 'gksu shutdown -h now', 'x-terminal-emulator -t sudo shutdown -h now', and even 'x-terminal-emulator -t shutdown -h now'. Nothing works.

My visudo file looks like this:

Code: Select all

# User privilege specification
root   ALL=(ALL:ALL) ALL
%shutdown ALL=(root)NOPASSWD: /sbin/reboot
%shutdown ALL=(root)NOPASSWD: /sbin/halt
%shutdown ALL=(root)NOPASSWD: /sbin/shutdown

%admin ALL=(ALL)ALL
%admin ALL=NOPASSWD: /sbin/reboot, /sbin/halt, /sbin/shutdown

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

Any help would be appreciated.

Thanks,

It would hel p if you were more specific than "not works". Do you get any error messages? Are there any entries in the system log?

I susepct that sudo wants a password but doesn't have a terminal to ask for it. You could try gksudo instead, or use visudo to edit /etc/sudoers to allow /sbin/shutdown to be run without a password.

Code: Select all

visudo

Then add

Code: Select all

yourusername ALL = NOPASSWD: /sbin/shutdown

I apologize for my vagueness; by "not works", I meant that the shutdown command simply wouldn't do anything. It wouldn't give any response at all.

But your suggestion worked perfectly. Thanks so much for your help!
