The system bell sound is annoying you. Which of the following can you use to change this and other userX preferences?

xset is the X user preference utility that allows users to configure X server settings including the bell (xset b [vol [pitch [duration]]]), key click, screen saver, mouse speed, and more. Running 'xset b 0' would silence the system bell entirely, or the volume/pitch can be adjusted as needed.

xconf is not a standard X utility - no such command exists in the X.Org toolset.

xbell is not a standalone X command - bell control is a sub-option of xset, not its own utility.

xmag is an X magnification tool that enlarges a portion of the screen for viewing, unrelated to user preferences.

xpref is not a real X utility - no such command exists in the X.Org toolset.
