Dear All, still me. Working on X configuration did not help me to find the problem.
I have been also looking in the /var/log/messages file, where I see this suspicious messages: 2013-04-24T01:18:53.991005+02:00 linux-3xop goa[23866]: last message repeated 2 times 2013-04-24T01:18:53.990935+02:00 linux-3xop dbus-daemon[560]: terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >' 2013-04-24T01:18:53.991297+02:00 linux-3xop dbus-daemon[560]: what(): boost::lock_error 2013-04-24T01:18:56.674087+02:00 linux-3xop systemd-logind[526]: Removed session 122. 2013-04-24T01:18:57.208721+02:00 linux-3xop xdm[581]: GdmManager: could not fetch uid of session '122': No such file or directory 2013-04-24T01:19:09.205729+02:00 linux-3xop dbus-daemon[560]: dbus[560]: [system] Rejected send message, 2 matched rules; type="method_return", sender=":1.0" (uid=0 pid=526 comm="/usr/lib/systemd/systemd-logind ") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.655" (uid=1001 pid=23715 comm="/usr/bin/gnome-session ") 2013-04-24T01:19:09.205745+02:00 linux-3xop dbus[560]: [system] Rejected send message, 2 matched rules; type="method_return", sender=":1.0" (uid=0 pid=526 comm="/usr/lib/systemd/systemd-logind ") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.655" (uid=1001 pid=23715 comm="/usr/bin/gnome-session ") 2013-04-24T01:19:09.257345+02:00 linux-3xop dbus-daemon[560]: dbus[560]: [system] Rejected send message, 1 matched rules; type="method_call", sender=":1.6" (uid=0 pid=617 comm="/usr/sbin/gdm ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.690" (uid=0 pid=24165 comm="/usr/lib/gdm/gdm-simple-slave --display-id /org/gn") 2013-04-24T01:19:09.257787+02:00 linux-3xop dbus[560]: [system] Rejected send message, 1 matched rules; type="method_call", sender=":1.6" (uid=0 pid=617 comm="/usr/sbin/gdm ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.690" (uid=0 pid=24165 comm="/usr/lib/gdm/gdm-simple-slave --display-id /org/gn") 2013-04-24T01:19:09.671702+02:00 linux-3xop kernel: [103103.982232] traps: gnome-shell[23876] trap int3 ip:7f9688dd908f sp:7fff8c7fbf30 error:0 2013-04-24T01:19:09.687707+02:00 linux-3xop dbus-daemon[560]: dbus[560]: [system] Rejected send message, 2 matched rules; type="method_return", sender=":1.0" (uid=0 pid=526 comm="/usr/lib/systemd/systemd-logind ") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.655" (uid=1001 pid=23715 comm="/usr/bin/gnome-session ") 2013-04-24T01:19:09.688044+02:00 linux-3xop dbus[560]: [system] Rejected send message, 2 matched rules; type="method_return", sender=":1.0" (uid=0 pid=526 comm="/usr/lib/systemd/systemd-logind ") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.655" (uid=1001 pid=23715 comm="/usr/bin/gnome-session ") 2013-04-24T01:19:09.691847+02:00 linux-3xop gnome-session[23715]: WARNING: Application 'gnome-shell.desktop' killed by signal 5 2013-04-24T01:19:09.825518+02:00 linux-3xop polkitd[615]: Unregistered Authentication Agent for unix-session:123 (system bus name :1.679, object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus) 2013-04-24T01:19:09.895364+02:00 linux-3xop xdm[581]: Failed to give slave programs access to the display. Trying to proceed. As you can see, it looks like the dbus-daemon exits throwing an exception, this causes the rejection of dus messages, and this in turns crashes the gnome shell BTW I tried the 3.8.1 iso images and I cannot reproduce the issue, so this must be related to updating 3.6 to 3.8.1 This is becoming supremely annoying as at home me and my wife switch user continuously during the day, and the 2nd or 3rd switch triggers the crash. If I cannot find the reason for this I think I will have to reluctantly switch to another distro (or DE). Grr, if someone has any idea...
