Some X servers may have alternative ways of providing the parameters described here, but the values provided via the command line options should override values specified via other mechanisms. :displaynumber The X server runs as the given displaynumber, which by default is 0. If multiple X servers are to run simultaneously on a host, each must have a unique display number. See the DISPLAY NAMES section of the X(7) manual page to learn how to specify which display number clients should try to use.
