<p>Glad to hear you got it working. And thank you for the link to
libffi6. We plan to have a native Ubuntu 20.04 version soon.<br>
</p>
<p>There are lots of reasons why your ChimeraX might be slow. Maybe
you have too many other programs running and are running out of
memory, or you have NVIDIA graphics and are using the open source
driver instead of the proprietary one, or your using an
underpowered laptop, or .... For us to give you a good guess
instead of a random guess, please use ChimeraX's Help / Report a
Bug dialog to send us some basic information about your computer
and how it is configured (use a recent daily build since there
have been recent improvements in the information gathering).</p>
<p> HTH,</p>
<p> Greg<br>

<div>Installed it successfully with Ubuntu 20.04 AFTER I
found where to get libffi6.</div>

<div>I got it here:<br>

<div>Now the only problem is that it runs very slow when
fetching a PDB file locally.</div>
<div>I think that my graphics is slow.</div>
<div>Thoughts?</div>

<p>Please try the Ubuntu 18.04 version, there's a good
chance it will work on 20.04. And please let everyone
know if it works or not. I will look into building a
20.04 version.<br>
