Do you start gnubg from some kind of menu or desktop icon ? If this is 
the case, could you try to start it from a terminal to see if there are 
some useful error messages, and if it ends immediately or runs but 
stays stuck early, before showing the GUI.

In the latter case, could you run top or "ps ux" in another terminal to 
see if it really does nothing or if it is using 100% of a CPU. Could you 
try using "gnubg -t" as well to see if running without GUI makes a 
difference


OpenSuse 15.1 release information claims that it provides a more recent 
gcc compiler. It is not clear how much change from 15.0 that means and 
how its packages were built, but your problem may be due to the 
following issue (gnubg 1.04 is older than that):

2015-10-07  Michael Petch  <address@hidden>
        Fix problem identified by
        Mike Frysinger where __attribute__ and  _GNU_SOURCE may not
        be properly defined in some situations. This may result in
        an infinite loop on newer compilers.

There were some discussions about this in this mailing list in 2015 when 
other distributions started to use the hardening features of gcc by default.
