I know, I can load X applications (X apps) as root with 'sudo xappname' and giving the password. But that takes too much time, every time I want to do something as root which involves the X server, I have to type the root password. But in other distros I was used to logging in as root in a shell (konsole) and typing 'xappname' and it would be displayed on the X server of the current user. But in Ubuntu I get Code: Xlib: connection to ":0.0" refused by server if I start gvim (my favorite editor) for example. I haven't found this issue on the web yet. Can anyone tell me, how to change the behoaviour of the X server of Ubuntu somehow, because root should really have every right shouldn't he? This is the only thing that keeps annoying me in Ubuntu.
xauth cookies That's what I know. It's not what I wanted to do (as I mentioned). Anyway, I figured it out. If you want to execute X apps as root (logged in as root in konsole or similar) while you are logged in with the user called user, you have two ways: 1. (prefered because more secure) Log in as root and do Code: cp /home/user/.Xauthority ~/ Then you can start an X app as root while user is logged in on the same X server. 2. To allow any user to access the X server while logged in as user, use the xhost command (being user): Code: xhost + Hope that helps someone who has the same problem.
