When I start the front-end of Mathematica 11.3 or 12.0 on Scientific Linux 6.10, I see the splash screen and after it says "Opening Welcome Screen" the splash screen vanishes and nothing happens. There are no windows showing up and also no messages in the terminal. The program is still running and there is a "Mathematica" process, two "WolframKernel" processes, a "java" and a "XML.exe" process showing up in the output of
ps aux. The only thing I can do is kill the process, e.g. via
This does not happen with Mathematica 11.1 or earlier versions and I can also successfully start just the kernel for 11.3 and 12.0 without the front-end. I've already removed the ~/.Mathematica folder, but nothing changes.
How do I even start to debug this?
