<p>systemd is not a dependency of GNOME: this page should instruct the user
to look in the syslog, and then expland that if systemd is running, the
logs will be redirected to the journal.</p>

<p>If you want to find more information about a problem in a session or want
to fix it, consult the system log, which stores log data for your user session
and applications.</p>
<p>The <file>~/.xsession-errors</file> X session log file has been deprecated
and is no longer used.</p>

<title>View session log on systemd-based systems</title>
<p>On systemd-based systems, you can find the session log data in the
<app>systemd</app> journal, which stores the data in a binary format. To view
the logs, use the <cmd>journalctl</cmd> command.</p>
<steps>
<title>To view your user session logs:</title>
<item><p>Determine your user ID (<sys>uid</sys>) by running the following
command: </p>
<screen><output>$ </output><input>id --user</input>
1000</screen></item>
<item><p>View the journal logs for the user ID determined above:</p>
<screen><output>$ </output><input>journalctl _UID=1000</input></screen>
</item>
</steps>
<p>For more information on the systemd journal, see the
<link href="man:journalctl"><cmd>journalctl</cmd></link>(1) man page.</p>
