There must be something up with your $PATH env. variable when you login as root. You should try running
to see the full path to nautilus.

So then if nautilus is /usr/bin/nautilus you would do:
BTW assuming you have KDE installed you can happily run konqueror from within GNOME.

Unfortunately it does not work: the command

which nautilus

causes the promt to go back to

linux: /home/channi

and nothing happens

Neither were there any results for

which konqueror

Now I found a file search tool in the start menu which shows me where the nautilus executable is.
So I can start the executable, but then I get the error message:

Authentication rejected reason: Non of the authentication protocols specified are supported and host based authentication failed.

Any other way I can use nautilus as super user?

There is something wrong with your setup then. It should work, I've tested it on completely seperate computers running RHEL4 and Mandrake/Mandriva 9.2 to 10.2.

What distro are you running?

Does this help?:

I am running suse 9.3.

Thanks for trying to solve this problem.
If there is a problem with the setup, does this mean re-installation, or is there a way to fix it?

So you're logged into the gnome desktop as yourself? And you open a terminal and type ? Then /usr/bin/nautilus?

An interesting development:

Now the message

Authentication rejected reason: None of the authentication protocols specified are supported and host based authentication failed.

still appears, but nautilus also opens, and I have been able to copy the relevant files into /etc.

Suse 9.3 puts the nautilus files into /opt/gnome/bin/

(And now I can play the pc levels of oxydmag on my linux machine (with enigma) I have learnt quite a lot in the process and this forum is really good.)

Thank you
