Hi Stephen,
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
https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2021-June/002339.html
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.

I am attempting the installation of ChimeraC-1.2.5(chimerax-1.2.5-rc-2021.05.24) on my up to date Debian v-1064 bit platform. I open the tar.gz package without any difficulties, but when I attempt to execute ChmieraX i get the following:

xcb is installed, but the Debian v-10 default version of python is 3.7. Is this the problem?
Is there a solution? Reinstalling did not fix the problem.
Thanks in advance.
