[chimerax-users] ChimeraX won't start on Ubuntu 16.04

[Paul Buscemi]

Greg,
 
Thank you very much for the response. Yes it does.. I was hoping….  
Chimera is a fine program and I hope you see your way into incorporating it or as a GUI/ file preparation system

 I will look ino ISOLDE/OpenMM

Regards,
Paul

So add that directory to the LD_LIBRARY_PATH environment variable and rerun ldd on libqxcb.so. And please let me know what you find out so I can make sure the .deb package avoids that problem.
