Comment (by ebordon):

 We are testing our builds, searching from this bug to occurs and we are
 catching some logs.

 We are using the follows command:

 {{{
 #!/bin/sh

 # Create a script, to preserve logs of user session
 cat <<EOF >/usr/local/bin/olpc-dm-preserve-logs
 #!/bin/sh
 NOW=\$(date +%s.%N)
 tar --create \
     --xz \
     --file /home/olpc/power-logs/\$NOW.tar.xz \
     --transform "s,^,\$NOW/," \
     /tmp/olpc-dm* \
     /var/log/Xorg* \
     /var/log/olpc-dm* \
     /home/olpc/.sugar/default/*.log || true
 EOF
 chmod +x /usr/local/bin/olpc-dm-preserve-logs

 # Preserve logs when olpc-dm service fails
 sed -i -e '/^ExecStart/aExecStartPost=/usr/local/bin/olpc-dm-preserve-
 logs' \
     /usr/lib/systemd/system/olpc-dm.service
 }}}

 And also, we configure the .xsession file in this way:

 {{{
 # Procedimiento log.
 ulimit -c unlimited

 # make a timestamp, seconds, nanoseconds.
 NOW=$(date +%s.%N)

 # make evidence of session startup.
 touch power-logs/startup.$NOW

 # if a previous session log is found, save it.
 LOG=/var/log/Xorg.0.log.old
 [ -e $LOG ] && \
     grep -qi backtrace $LOG && \
         xz < $LOG > power-logs/backtrace.$NOW.xz
 }}}
