XERROR: 'Xlib: connection to ":0.0" refused by server'

tsiMental · 04-02-2005, 09:41 PM

After I installed/converted to Debian Sarge. I get the following error message whenever I try to start a GUI-program from a Konsole in KDE. I am running a 2.6.8-2-686-smp kernel.

Quote:

Xlib: connection to ":0.0" refused by server

Xlib: No protocol specified

Does anyone know how to fix this error?

Are you trying to do this as the user who started the X session? If you are trying to do this as root or a user who didn't start the X session, then you need to do "xhost +localhost" before using "su" to switch to root or another user.

Tried it:

Quote:

user@linuxpc:~$ xhost +localhost
localhost being added to access control list
user@linuxpc:~$ su
Password:
linuxpc:/home/user# kedit
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

kedit: cannot connect to X server :0.0
linuxpc:/home/user#

Need this to edit configfiles as root (in an easy way).
If I pop up a terminal an type kedit as user, then kedit starts fine...

See if this helps, from the mepislover forums.

To fix the xhost error you see sometimes when you try to run a program as root from a terminal:

edit your /etc/kde3/kdm/Xservers file
On the line that says:
:0 local@tty1 /usr/X11R6/bin/X -nolisten tcp
Change it to:
:0 local@tty1 /usr/X11R6/bin/X -ac -nolisten tcp

Got this info from http://www.mepis.org/node/view/4535 which Carlos provided the link for.

"Need this to edit configfiles as root (in an easy way)"

You could also right click desktop choose the run command and enter "kdesu kedit" then enter root password. Just another option I thought maybe of interest or help good luck

With your favorite editor, open /etc/profile

Example: # nano /etc/profile

and add this line:

export XAUTHORITY=/home/your_user_name/.Xauthority

inserting the username you're using in this box, obviously.

save/exit

logout/login

You can edit config files with a console only editor like nano/pico, emacs, vi/vim etc. You don't realy need to start a gui text editor, but if you are not familiar with the others then the "kdesu" command suggested above is ok to use.

Use "sux" instead of "su"

the file /root/.Xauthority does not exist... Does that matter?

Tnx nurb!!! Works now, needed to reboot after I'd done this.

btw: "sux" didn't work in my Konsole...

I don't have /etc/kde3/kdm/Xservers.

Code:

# cd /etc/kde3/kdm
# ls
backgroundrc  kdmrc  kdmrc.dpkg-dist  Xaccess  Xreset  Xsession  Xsetup  Xstartup  Xwilling
#
