I have been unable to get HGM's modified xboard (for duck chess) to work consistently under linux debian: https://talkchess.com/forum3/viewtopic.php?f=7&t=80829&sid=71ffce791c5430316d4bad03598012cd&start=200#p945483
I decided to start over with my debian VM on my work PC. I installed the standard xboard software, as well as a few chess engines (including stockfish 12). Most of the engines seem to work as expected, but stockfish 12 never makes any moves. Does this sound familiar to you?
