But in the meantime the mailing list message I linked to suggested a fix to a reported Qt xcb load problem that involved installing some missing package and you could try what it suggests. I know Greg strongly discourages using the "generic Linux" ChimeraX distribution because this kind of missing library problem you describe is common since Linux distros vary so much in what system libraries they include.<div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Tom</div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Oct 8, 2021, at 12:50 PM, Stephen P.

Hi Stephen,

<div class="">� Our linux ChimeraX expert is on vacation but here
is an idea. �The problem is that the Qt window toolkit can't
start and that is almost surely a missing system library,
probably one that the Qt xcb plugin shared library needs. �I see
a ChimeraX mailing list discussion of this problem here</div>

<div class="">Supposedly the ChimeraX 1.2.5-1 builds on the
download page solved that issue. �If you are using the "generic
Linux" ChimeraX distribution I'd suggest instead using the
Ubuntu 18.04 ChimeraX version which is a .deb file for debian 10
according to the ChimeraX download page. �The advantage of using
the .deb distribution is that it uses the Debian package manager
to assure the needed libraries are installed, while the "generic
Linux" ChimeraX .tar.gz file tries to include �the needed
libraries but not always successfully since different linux
distros include different system libraries.</div>
