kwrite(12926): Session bus not found
To circumvent this problem try the following command (with Linux and bash)
export $(dbus-launch)

KCrash: Application 'kwrite' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/root/.kde4/socket-localhost/kdeinit4__0

[1]+ Stopped kwrite /etc/X11/xorg.conf

So that the file will open the dbus command has to be run everytime.
I have tried running other files and get the same error message

You can't run KDE apps easily as root, because that's what you are trying to do.
Use another editor for that, like mcedit (of Midnight Commander) on a terminal.

before you try to run gui apps as root type this as user:

Code: Select all

xhost +

This has nothing to do with X access controls, but with the fact the there is no dbus session running for the root user.
You see that above in the error message in the first line: "Session bus not found [...]" and kdeinit is not running for the root user.

One could try running it with kdesu, by doing it like this:

Code: Select all

/usr/lib/kde4/libexec/kdesu kwrite

In a konsole use

Code: Select all

su -

for a full root environment.

Code: Select all

kwrite

will then work as expected.

The su - and kwrite works properly with no dbus-launch error

Thanks for the reply and the help

Marking as solved
