<div dir="ltr">Hi,       When i run the dbus binaries on the arm platform the dbus-launch , dbus-uuidgen and dbus-cleanup-socket  are working fine... But when i am running the dbus-monitor the following error is coming: Failed to open connection to session message bus: Failed to execute dbus-launch to autolaunch D-Bus session When i am strace to that dbus-monitor it shows like this <meta http-equiv="CONTENT-TYPE" content="text/html; charset=utf-8"><title></title><meta name="GENERATOR" content="OpenOffice.org 2.3 (Linux)"> <style

Process 1053 detached =================================================== when i am compared this one with my i686 machine strace dbus-monitor the difference is It not starting the socket on the arm platform(MSM 7200 board).Please give me the solution to run the dbus-monitor on the arm platform. </div>
