There is a race when gnome-session launches dbus. I think running a -rt kernel seems to make it occur more often. The bug that is happening (or something very similar) is described here:
http://bugzilla.gnome.org/show_bug.cgi?id=395488 I have strace'd the launch myself and I also find that the dbus child process receives a SIGPIPE. Any easy fix for this is to change your gnome session script to launch dbus before gnome-session. Then gnome- session wont try and start dbus itself. In /usr/share/xsessions/gnome.desktop change the line: Exec=/usr/bin/gnome-session to Exec=dbus-launch /usr/bin/gnome-session -- epiphany launch error: Unable to connect to session bus https://bugs.launchpad.net/bugs/85118 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
