You have three choices: Run XDM on the console and use the X servers builtin screenblank. Or you can run the 4.1.x screenblank in compatabilty mode. Or you can compile you own screenblank from sources available from ftp://ftp.ececs.uc.edu/pub/sun-faq/Source/screenblank_27dec94.tar.Z You can always get the current screenblank from ftp://ftp.ee.lbl.gov/ or ftp://ftp.netcom.com/pub/je/jef/ Last Updated: Sept 18, 1995.
