Re: Shutdown/Reboot Ubuntu

The problem is that the 'shutdown' command used by IceWM can be executed only by 
root. (This is the default case for most (all?) Linuxes.) Here are a few 
choices:

1) Use sudo to give permission to regular users to execute the 'shutdown' 
command without password prompting. This requires editing your sudoers file 
(with visudo) but is probably better than the following option. I set my box up 
so all member of the 'plugdev' group can execute 'shutdown'. I did this by using 
visudo to add:

%plugdev ALL=NOPASSWD: /sbin/shutdown

as the last line in the sudoers file. To power down, configure IceWM to use:

sudo shutdown -hP now

To reboot:

sudo shutdown -r now

2) Set the 'sticky' bit on the shutdown command to give all users the ability to 
execute the 'shutdown' command directly. The problem with this approach is that 
if the 'shutdown' command get an update in the future, you will have to set the 
sticky bit again. As root:

chmod u+s /sbin/shutdown

(I think this is correct! I haven't done this in a while.)

3) If you have Openbox and GDM installed as well, you can use 'gdm-control' to 
handle the power stuff. See the man pages for gdm-control if you want to do it 
this way.
