<h1 class="title">General/Other Troubleshooting</h1>
<p><strong>Issue 1: I am seeing messages like "Unable to find GUI for username..." and "No GUI available" in the system log.</strong></p>
<p>Solution:</p>
<p>These are normal and should not cause any concerns.</p>
<p><strong>Issue 2: How do I check the syslog for HPLIP system errors?</strong></p>
<p>Solution:</p>
<p>With superuser (su/sudo) privileges, use the following command to view the syslog. Look for any errors during the time of the failure.</p>
<pre class="literal-block">
# tail -f /var/log/messages
</pre>
<p><strong>Issue 3: When I go to login to the CUPS web interface (http://localhost:631) it asks for my root password--and my root password doesn't give me access.</strong></p>
<p>Solution:</p>
<p>First verify with your distribution the best way to install your printer.</p>
<p>To enable the CUPS web interface follow these directions.</p>
<p>Edit the cupsd.conf file.</p>
<pre class="literal-block">
# gedit /etc/cups/cupsd.conf
</pre>
<p>Find this section:</p>
<pre class="literal-block">
# Restrict access to the admin pages...
<Location /admin>
#Order allow,deny
#Allow localhost
</Location>
</pre>
<p>Change it to:</p>
<pre class="literal-block">
# Restrict access to the admin pages...
<Location /admin>
Order allow,deny
Allow localhost
</Location>
</pre>
<p>Save/Exit, restart CUPS:</p>
<pre class="literal-block">
# /etc/init.d/cups restart
</pre>
<p>for Ubuntu</p>
<pre class="literal-block">
$ /etc/init.d/cupsys restart
</pre>
<p>Open your web browser, go to <a class="reference" href="http://localhost:631">http://localhost:631</a>. Complete the administrative tasks you need to complete.</p>
