I am using kde 4.4.5. When I try to run an application that needs root, I am asked for root password. In gnome I am asked for my password.

Gnome used gksudo, gksu-properties is configured to use sudo mode. I have no root password (it is not set on this machine).

I am not getting the kdesudo box when launching applications that are marked in menu editor as run as another user, I think there is a problem with the way the KDE desktop environment is setup.

How do I tell the kde menus to use kdesudo?

Have installed kdesudo, but it makes no difference.

I originally installed the default system, without kde. I then added kde. I just added kde-full. (still not working)

I have discovered that some admin applications launch properly, they have as there command gksudo …. I think this is not perfect as it will cause gtk libraries to load unnecessarily.

Please try sudo apt-get install kubuntu-desktop – izx Jul 16 '12 at 11:55

This is a bit of a hack, but gets the job done. Unfortunately it needs to be done for each offending application, in turn. And it will cause kdesudo to be used in gnome.

Right click on launcher icon, select menu editor. Find application, then in advanced tab remove tick for run as a different user, and in General tab edit command to be preceded with kdesudo.
