This problem where ChimeraX won't start on Linux and complains about Qt plugin xcb was discussed a few months ago

Apparently it means that the Linux system is missing a needed library. And the above discussion says ChimeraX 1.2.5.1 on Linux fixed the problem.

Hi Vanessa, Please send ChimeraX questions to chimerax-users@cgl.ucsf.edu (CC'd here, so no need to do anything this time).
Since I don't know the answer, I kept waiting for somebody else to answer your question... and didn't notice until now that you had sent it to only me.

Dear ChimeraX development team,
We encountered issues while installing ChimeraX on our server and wanted to ask whether you could help us understand what the problem is? We haven't yet found a solution to our problem. Here is the output after installation:
# /home/apps/chimerax-1.2.5-rc-2021.05.24/bin/ChimeraX X11 connection rejected because of wrong authentication. qt.qpa.xcb: could not connect to display localhost:10.0 qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

We would greatly appreciate your advice on how to solve this issue.
Many thanks for your help!
