<p>The nugget of good news was that you were able to install
ChimeraX using apt-get. That means all of the dependencies we
currently know about were installed. So the problem is probably
that either (A) you need to update your graphics driver or (B)
that we missed a dependency.</p>
<p>For (A) we recommend the proprietary Nvidia driver if you have
Nvidia graphics, or the open-source drivers if you have AMD or
Intel graphics. Please send me the output from "lspci | grep VGA"
so I can see what graphics device(s) you have.<br>
</p>
<p>For (B), please send me the output from running:</p>
<p> ldd
/usr/lib/ucsf-chimerax/lib/python3.9/site-packages/PyQt5/Qt/plugins/platforms/libqxcb.so</p>
<p>If there is a line that says "not found", then we have found the
missing dependency, and I can add it to future deb packages so
other people don't have this problem. But there could be other
errors that show up.</p>

<p>Dear ChimeraX users,</p>
<p>I have a problem with the installation of ChimeraX under Debian
10 buster. <br>
</p>
<p>I downloaded the ucsf-chimerax_1.3ubuntu18.04_amd64.deb from
the official website. I installed it one time with: <i>sudo
dpkg -i </i><i>ucsf-chimerax_1.3ubuntu18.04_amd64.deb </i>and
also with <i>sudo apt-get install ./</i><i>ucsf-chimerax_1.3ubuntu18.04_amd64.deb.</i>
Both times I get the same error message:</p>
<p>qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "
" even though it was found. This application failed to start
because no Qt platform plugin could be initialized. Reinstalling
the application may fix this problem.</p>
<p>The full error message is as attachment in this mail.</p>
<p>I searched the web for an answer and came up with three entries
of this mailing list. I followed the described way in these
mails, but nothing worked for me (1st mail:
