Actually, as I read this again, I noticed that it is behaving as per the spec:
XBell(dpy, 100) with base = 0: base - [(base * percent) / 100] + percent = 0 - 0 + 100 = 100 XBell(dpy, 100) with base = 100: base - [(base * percent) / 100] + percent = 100 - 100 + 100 = 100 So... this just seems a bit deceptive... if 'xset -b' is supposed to mute the keyboard bell, why was XBell() designed to work around this?
