Hello

In order to edit /etc/apt/sources.list I opened Konsole, and typed "su -" to get root-privileges. Become root, I typed

Code:

# kwrite /etc/apt/sources.list

and I got this answer:

Code:

Invalid MIT-MAGIC-COOKIE-1 keykwrite: cannot connect to X server :0.0

I tried another time, but typing "sux" instead of "su -" and all worked fine.
Which is the right command to get root-privileges and be able to launch graphical applications like kwrite?

Thanks for the help

Kano

That is sux if you want to stay root. If you want to execute only one command for X as root you can press alt+f2 then kdesu app or from cli you can use gksu app.
