X Window server
The xmetax program may start the local X Window server automatically. The statement
serverCommand server_program server_argument...
declares the name of the X Window server program and its arguments. All words up to the end of the command line or the configuration file are taken as server_argument.... Since succeeding key words are not recognized, this statement must be the last on the command line or in a configuration file.
Contrary to other configuration statements, the arguments of all serverCommand statements are concatenated.
In most cases, the first server_argument is the non-default display number :1 (Display connection).
The xmetax program transparently passes the signals HUP, TERM, and USR1 and takes care of correct authorization automatically (Authorization).
The statement
serverNice nice_value
changes the relative process priority of the X Window server process. A negative nice_value from -1 to -20 increases the priority, a positive nice_value from 1 to 20 lowers the priority, the default value is 0.
