X.org / X-server HowTos

Fix: /bin/dbus-launch terminated abnormally without any error message and solution

Posted on in Categories , , , , last updated March 23, 2014

I am a new Linux server user. I need to tunnel X over ssh. I type the following command on a CentOS/RHEL based remote host to get display on a local desktop:

ssh -X [email protected]
xeyes &
firefox &

But, I am getting an error that read as follows:

**error**: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details – 1: Failed to get connection to session: /bin/dbus-launch terminated abnormally without any error message)

How do I fix this error on a newly formatted/installed RHEL or CentOS Linux 6.x server?

I am a new Linux server user. I need to tunnel X over ssh. I type the following command from OS X Unix terminal to login into far_away_machine (a centos server):

ssh -X -o options -A -p 22 [email protected]

But, I am getting the following error on screen:

X11 forwarding request failed on channel 0
Last login: Sun Mar 23 15:58:51 2014 from 1.2.3.4

How do I fix “X11 forwarding request failed on channel 0” on Linux or Unix-like systems?

Where Is The Xorg.conf File Located under Unix / Linux / BSD?

Posted on in Categories last updated April 24, 2012

I want to find and edit my xorg.conf file for tweaking and configure it for new settings. The problem is that I’m unable to find the file. According to my research, xorg.conf should in /etc/X11 or /usr/X11R6/lib/X11/ directory. I found directories but not the file in directories. How do I find the xorg.conf under Unix or Linux like operating systems?
