[KDE4] in Konsole sudo can not execute programs (e.g. kate)

[Onlinelli]

in KDE 4 (Hardy) i cannot exectute programms with 'sudo', e.g. editing the xorg.conf with kate.

nelli@chuck-norris:~$ sudo kate /etc/X11/xorg.conf
sudo: kate: command not found

What the output of the following command on your system?
$ sudo sh -c 'echo $PATH'

For me it works, and the output is:
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

$ sudo sh -c 'echo $PATH'

gives

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

but for me it still does not work.... How can I provide more information?

Same problem here.
I use Hardy-KDE4 64 bit and there is no way for me to execute kate or kwrite with su-permissions. kdesu gives the same error (command not found).
My Path is the same as Daniel's (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin) but it seems kate-kde4 (which is also known to the system as kate) is located in /usr/lib/kde4/bin/kate which is obviously not in the path.
It works as normal user, so it seems the problem is restricted to the root-path.

I tried adding /usr/lib/kde4/bin to my path, but that just works for the userpath.
So echo $PATH now shows '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/kde4/bin' but it still can't find kate.
The strangest thing is, that tab completion for sudo ka<Tab> shows kate, but when i to execute it won't find it.
Executing sudo /usr/lib/kde4/bin/kate directly does work though...

This bug is a duplicate of https://bugs.launchpad.net/ubuntu/+source/kdesudo-kde4/+bug/191264 so it should be closed.

[Ralph Janke (txwikinger)]

sudo should not be used to start kde applications from commandline. Please use kdesu or kdesudo instead.

However, both those have the same problem as seen in https://bugs.launchpad.net/ubuntu/+source/kdesudo-kde4/+bug/191264.
