Why can't I start a X application from Konsole root logged ?

MaikoID · 08-24-2011, 04:36 PM

Hi, I'm using Kubuntu 11.04. In all Ubuntu's versions I always did the login with root in a terminal using the command:

Code:

sudo su -

then I put my password, after this I could do everything until I close the terminal. In Kubuntu 11.04 I can't do that.

Code:

maiko@maiko-laptop:~$ sudo su -
[sudo] password for maiko: 
root@maiko-laptop:~# kate
No protocol specified
kate: cannot connect to X server :0
root@maiko-laptop:~# kpackagekit 
unnamed app(2644): KUniqueApplication: Cannot find the D-Bus session server:  "//bin/dbus-launch terminated abnormally with the following error: No protocol specified
Autolaunch error: X11 initialization failed.
" 

unnamed app(2643): KUniqueApplication: Pipe closed unexpectedly. 

root@maiko-laptop:~#

Could anyone explain to me why can't I start a X application from root's terminal in Kubuntu?

Use kdesu

sudo frontend for KDE
KdeSudo is a graphical frontend for the sudo utility, which allows users to run programs as root (or another user) by giving their own password.

Same error:

Code:

root@maiko-laptop:~# kdesudo kate
No protocol specified
kdesudo: cannot connect to X server :0
root@maiko-laptop:~#

Try running

Code:

kdesudo kate

as a user that has sudo privileges not as root.

I don't want to start my applications as a normal user, I want to do that with root privilegies without exit from my current terminal session or write the password again. I always did that in ubuntu why is it different in Kubuntu ?

You will be running the application with root privileges, using sudo to elevate your user.

Code:

kdesudo kate

then enter your user password to run kate as root.

you aren't understand me. I don't want to leave my current opened root shell session, I would like to have a behavior similar to Ubuntu.

I don't want to type root's password again.

You run "kdesudo" as a normal user, not as root.

And by the way, isn't it "kdesu", not "kdesudo"?

That is what I thought, but I guess not.
