using sudo while gksu is broken....

jeff story · 2010-08-17 20:44:14

My gksu is broken per bug http://bugs.archlinux.org/index.php?do= … k_id=19614

My desktop environment is Gnome 2.30.2

My question is what are the potential problems associated with using sudo for gui apps until the gksu bug is fixed?

example: sudo nautilus

Are you sure you are using gksu rather than gksudo?

For me:

 dave ~  $  gksu nautilus

works fine, but:

 dave ~  $  gksudo nautilus
sudo: sorry, a password is required to run sudo

So, I will use gksu on the very rare occasions I need to run a gui with privs.

If you launch gui apps with sudo it will be fine 90% of the time. The rest of the time it will screw the permissions in your home (e.g. changing .ICEauthority to root) and you won't be able to log in to X until you fix it. So, avoid doing that.

I have had a gnome "new menu" item that ran "gksu nautilus" as an "application", that has worked fine since day one.

It just stopped working with no "gui" errors after my last update.

When I run gksu nautilus in the terminal, I get a pop up dialog box asking for my password, I enter my password, then the terminal output is below.

[jeff@Arch2009p2 ~]$ gksu nautilus
sudo: sorry, a password is required to run sudo
[jeff@Arch2009p2 ~]$

I get the exact same results when I substitute gksudo for gksu.

[jeff@Arch2009p2 ~]$ gksudo nautilus
sudo: sorry, a password is required to run sudo
[jeff@Arch2009p2 ~]$

Look under System / Preferences / Privilege Granting

Is Authentication set to su or sudo?

If it's set to sudo try changing it to su.

That did it. Now I get nautilus listed as running as root .
However, see the terminal output, and no prompt for password!

[jeff@Arch2009p2 ~]$ gksu nautilus

(nautilus:9728): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported

[jeff@Arch2009p2 ~]$

Ths sudoers file using my fav editor Nano via: EDITOR=nano visudo

  GNU nano 2.2.5                                        File: /etc/sudoers.tmp
