You are missing the X11 screen saver shared library. "yum search Xss" shows that it is provided by the libXScrnSaver package. So your IT can do a "yum install libXSrcnSaver" to make it available.

I have been working with my IT department to port a script that uses Chimera from an old linux machine to a new Linux machine running RHEL.

I setup my own test node at home with RHEL (same version). I got the script working on my test node. I am now moving the system to the IT node. When I reinstalled the same version of Chimera (Chimera64-2024-04-12) on that machine and run the script when Chimera starts I get Tkinter errors and others (see below).

What do I need to do to get this version of Chimera running? Any suggestions would be appreciated. Should I try a more current build?
