How to reset iPython/Jupyter profile after upgrade to 'factory' defaults?
<p>Returning to using iPython Notebooks after a year, [I installed my distro's version of Jupyter and now] Jupyter launches without menu bar. I'm guessing some of my old settings are carrying over. I'm guessing the fastest way to fix this is to .bak the old profile and create a new default.</p>

<p>First, initialized a Jupyter profile from <a href="https://groups.google.com/forum/#!topic/jupyter/7q02jjksvFU" rel="noreferrer">instructions on how-to setup multiple Jupyter profiles</a>:</p>

<pre><code>$ jupyter notebook --generate-config
</code></pre>

<p>Then, [after further investigation] I created a new iPython profile,</p>

<pre><code>$ ipython profile create foo
</code></pre>

<p>I followed <a href="https://stackoverflow.com/questions/28253864/setting-ipython-default-profile">found advise</a> to renamed <code>profile_foo</code> to <code>profile_default</code>. Then, </p>

<p>Still not reset to 'factory'. What am I missing?</p>

<p>UPDATE: [edit] plus, I reordered what were my actual rebuilding profiles steps--in case there is some propagation of settings, where the order matters (haha. Maybe I'm recreating the incorrect order...?)</p>
