This has been asked and answered quite a few times already.

See here e.g. for how to configure kdesu to use sudo (and respect its settings) instead of the default su: https://forums.opensuse.org/showthread.php/512950-How-use-quot-sudo-quot-without-password?p=2750273#post2750273

Thanks
i use this command and worked but that for all apps kdesu

kwriteconfig5 --file kdesurc --group super-user-command --key super-user-command sudo

How do I go back to an earlier state?

but i want for apply selected my app (software management and gparted)

Delete the file ~/.config/kdesurc .

But why would you want to, if it works and does what you wanted?

but i want for apply selected my app (software management and gparted)

This works for all apps started via kdesu or xdg-su (when using KDE).
And in particular for YaST (Software Management).
If you are not using KDE, then your question was wrong in the first place though… :wink:

I’m not sure at the moment how gparted is started by the standard menu entry, I’d have to look.
But you can use KDE’s menu editor to change the start command.

I wanted and I did, but I asked to know
Your order will not be imposed on only a few apps under kdesu (except gparted)
I applied a few apps on sudo (/etc/suders)
Can the same thing be done kdesu(/.config/kdesure)
Not all of them for just a few programs kdesu

Ok, I was just just surprised about that question…

Your order will not be imposed on only a few apps under kdesu (except gparted)

It should work with all apps you start using kdesu.
And therefore for all apps using xdg-su as well when run inside a KDE session as I wrote.

I had a look though, and gparted uses a command named /usr/sbin/gparted_polkit to start it.
This in turn uses pkexec to start it.

So you should be able to configure that to not require a root password via the polkit settings…

I cannot tell you how to exactly do that at this point though.
I did explain how to run YaST via pkexec without requiring a root password in the past, maybe that will help.

After the change, kdesu uses sudo as mentioned, and should just respect everything you changed in /etc/sudoers.

But again, this only applies to kdesu, or xdg-su run in a KDE session (where it uses kdesu).

PS, particularly I mean:

If you replace “/usr/sbin/yast2” there with “/usr/sbin/gparted”, it should work I think.

I.e. create a file /usr/share/polkit-1/actions/org.opensuse.pkexec.gparted.policy with the following content:

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE policyconfig PUBLIC
 "-//freedesktop//DTD PolicyKit Policy Configuration 1.0//EN"
 "http://www.freedesktop.org/software/polkit/policyconfig-1.dtd">
<policyconfig>

  <action id="org.opensuse.pkexec.gparted">
    <message>Authentication is required to run gparted</message>
    <icon_name>gparted</icon_name>
    <defaults>
      <allow_any>auth_admin</allow_any>
      <allow_inactive>auth_admin</allow_inactive>
      <allow_active>yes</allow_active>
    </defaults>
    <annotate key="org.freedesktop.policykit.exec.path">/usr/sbin/gparted</annotate>
    <annotate key="org.freedesktop.policykit.exec.allow_gui">true</annotate>
  </action>

</policyconfig>

But I have not tested this… :wink:

Thank you very much for help
I have a question
i run this command

kwriteconfig5 --file kdesurc --group super-user-command --key sup
er-user-command sudo

then added this command /etc/sudors.

 think_alone ALL=(ALL) NOPASSWD: ALL

and worked for all apps kdesu
But why, when I run dolphin super user mode because it will remove the icons? (So simple it does not have all the graphics mode) this problem have for “kdesu systemsettings5”,too

#9

Well, you either set a icon theme for root that doesn’t contain the corresponding icons (you could change that with “kdesu systemsettings5”), or the applications do not detect that they are running inside a KDE desktop because sudo doesn’t forward the corresponding environment variables.

Try to add “XDG_CURRENT_DESKTOP” to the env_keep list in /etc/sudoers.
