[kde-linux] sudo kjobviewer ?

[Alain M.]

How do I run kjobviewer as root without entering a password?

It should be possible using sudo, but it isn't, or al least not as
   sudo kjobviewer --all

All I ger is:
   ERROR: Communication problem with kjobviewer, it probably crashed.
and kjobviewer is running in memory as root but not visible

I am using Mandriva 2007 with KDE 3.4.5

thanks in advance,
Alain
