  <title>Debug session problems</title>

  <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>

<section id="session-log-systemd">
  <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 its:translate="no" href="man:journalctl"><cmd>journalctl</cmd>(1)</link>
  man page.</p>
