no access to display as root

rdking · 2005-06-23 12:31:01

anytime I try to run a program as root from a console i get an error opening display. Can someone let me know how to rectify it:

[root@myhost ryan]# kate /etc/rc.conf
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

kded: cannot connect to X server :0
kded: ERROR: KUniqueApplication: Registering failed!

you're not supposed to run a program as root while in regular user.

Do you mean console (no x sessions started) ore a terminal while user is logged into kde?

via terminal while user is signed into wm. So I have to exit X, sign in as root to simply modify a file not wrtieable by the user?

you cant open a display as root while in a regular user is what I meant. If you need to open up that program do it as regular user.

like penguin said, it's recommended, highly to not run X apps as root... there is no good reason for it, ever...

that said, running "xhost +localhost" as a user will cause X to accept root connections....

just *don't do it* -this is informational only

why am i never having problems with this?
i'm using lazy-pac(pygtk) as root without problems,

there is also a wikipage explaining what phrakture said,

Usually, I use emacs as root without any problems. I use a setup similar (same?) to the one described in the wiki.

Also, some X apps like qtparted needs to be run as root. :?

what about compiling a kernel or editing a system config file with gvim? I think those are very good reasons to have root access X apps

Are you using KDM? It's default settings block apps running from root. For a quick work-around, try using a CLI based editor like nano or vim, or switch over to GDM. I did the latter.

use vim from a terminal then... the *terminal* can be started as a user, then you just su over
