root user can't open display


I have been having problems with this for ages now...ane never figured out what's going on. The problem is that I can't run Gnome applications as root. Here is an example of what happens when the root user tries to run galeon:

bash-2.05a# galeon &
[1] 17824
bash-2.05a# Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Gtk-WARNING **: cannot open display: :0

[1]+ Exit 1 galeon


okay, so I don't need to run galeon as root anyway, but some apps such as ethereal do require superuser status.

Does anyone know what's going on here?

Hey chris...what if when I do xhost + and I get "xhost: not found"? I'm trying to start the VNC server on my box and when I start it, the log (../hostname:1.log) says, "xhost: unable to open display hostname:1"

well if that's a file not found error, mine is in /usr/X11R6/bin/xhost, so check you've nto got a path issue, assuming it's there somewhere - use whereis, find or locate.

Sorry about the double post...

Anyhow, I found xhost (/usr/X/bin), but when I issue the command:

xhost +myhostname

I get:

/usr/X/bin/xhost: unable to open display ""

Try doing it as the user who runs the X server from within an xterm. You should be able to put it in your .xinitrc too, if one exists.

Or if you're running 'su -' to become root and running your app within the root shell,
export XAUTHORITY=~<xuser here>/.Xauthority
before your run your app. Put it in root's .profile if you want it to stick.

root user can't open display

edit your /etc/X11/gdm/gdm.conf
You'll find a line which start your X :
X -a-lot-of-options
add "-ac" to this line.

Restart your gdm
/etc/init.d/gdm stop
/etc/init.d/gdm start

log as normal user. Su as root
export your display :
export DISPLAY=:0

try with xterm.
