The xsetroot command sets the default cursor, so you can make it be the more normal arrow
cursor pointing to the top left. Other fun options, depending on your cursor theme, are 'boat', 'trek', 'shuttle' and 'hand1'. This all depends on the Xcursor "theme" you have selected, of course. You can put this command in your ~/.xinitrc file so it always runs when you
begin your X session.
