[chimerax-users] ChimeraX 1.3 not working fully on Manjaro Linux - missing libraries

[Greg Couch]

linux-vdso.so.1 is preloaded, so that is not an issue.  And LIBRARY_NAME 
is not literal, look for "not found".  If it is not one of those 
libraries, then try checking all of the other libraries in that directory.

This could also be a Wayland problem.  If Manjaro has switched to 
Wayland by default, you could fix this by switching back to X11. Another 
fix is to use the ChimeraX daily build if you can.  The current ChimeraX 
Linux daily builds have switched to Qt6, which has better Wayland 
support, but only for Ubuntu 20.04 and CentOS 8.  Ideally you would 
convert the Ubuntu 20.04 .deb or the CentOS 8 .rpm to a Manjaro package, 
and install that.  It is also possible to install the pypi versions of 
PyQt6 and PyQt6-WebEngine by hand to switch any daily build to PyQt6.  
Assuming CHIMERAX is the directory where ChimeraX is installed:

     sudo CHIMERAX/bin/python3.9 -m pip install PyQt6 PyQt6-WebEngine

Look at the chimerax symbolic link to see where it was installed.   
CHIMERAX/bin should *not* be on your path.
