Enabling .xsession
This page explains how to enable Telepathy debug output on your XO. If you haven't already seen Attaching Sugar Logs to Tickets, see that page first.
- First you need to enable your /home/olpc/.xsession file
cp /home/olpc/.xsession-example /home/olpc/.xsession
- Then edit .xsession and uncomment the lines about GABBLE_DEBUG, GABBLE_LOGFILE, SALUT_DEBUG and SALUT_LOGFILE
- For debugging lower level problems in the Telepathy connection managers, enable LM_DEBUG (for telepathy-gabble) or GIBBER_DEBUG (for telepathy-salut). Note that these will produce much bigger log files.
- reboot
Telepathy log files are now available at /home/olpc/.sugar/default/logs/telepathy-gabble.log and /home/olpc/.sugar/default/logs/telepathy-salut.log . Be sure to attach these files if you submit a ticket about a Telepathy issue.
Capturing core files
Core files are produced when a program crashes and contain useful debugging information.
As root:
echo /tmp/core-%p-%e > /proc/sys/kernel/core_pattern
This tells the kernel to put core files into the /tmp directory.
To make this persist across reboots, add the following line to /etc/sysctl.conf:
kernel.core_pattern = /tmp/core-%p-%e
Add the following line to /home/olpc/.xsession:
ulimit -c unlimited
This turns off any limit on core file size.
