(Get the code!)
Ok, sorry, dont have that tool as i dont have nvidia, just guessed where it could be and missed.
Problem is with Segmentation fault line between handler messages. That is result with which program ended, which means, program crashed (fault of program, never should do that).
So, try running "DISPLAY= sudo /usr/bin/nvclock -S -5", what will it report that. In other words, we need to know if that tool does need access to X server to work. If it does dim screen anyway, it does not need it. Post what it does return.
