When the same information is supplied in more -than one way, the highest precedence mechanism is used. The list of -mechanisms is ordered from highest precedence to lowest. Note that not -all parameters can be supplied via all methods. The available command -line options and environment variables (and some defaults) are -described in the Xserver(__appmansuffix__) and -__xservername__(__appmansuffix__) manual pages. Most configuration file -parameters, with their defaults, are described below. Driver and module -specific configuration parameters are described in the relevant driver -or module manual page. -.SH DESCRIPTION -.B __xservername__ -uses a configuration file called -.I __xconfigfile__ -and files ending in the suffix -.I .conf -from the directory -.I __xconfigdir__ -for its initial setup. -The -.I __xconfigfile__ -configuration file is searched for in the following places when the -server is started as a normal user: -.PP -.RS 4 -.nf -.IR /etc/X11/ <cmdline> -.IR __projectroot__/etc/X11/ <cmdline> -.IB /etc/X11/ $XORGCONFIG -.IB __projectroot__/etc/X11/ $XORGCONFIG -.I /etc/X11/__xconfigfile__ -.I /etc/__xconfigfile__ -.IR __projectroot__/etc/X11/__xconfigfile__. <hostname> -.I __projectroot__/etc/X11/__xconfigfile__ -.IR __projectroot__/lib/X11/__xconfigfile__. <hostname> -.I __projectroot__/lib/X11/__xconfigfile__ -.fi -.RE -.PP -where -.I <cmdline> -is a relative path (with no \(lq..\(rq components) specified with the -.B \-config -command line option, -.B $XORGCONFIG -is the relative path (with no \(lq..\(rq components) specified by that -environment variable, and -.I <hostname> -is the machine's hostname as reported by -.BR gethostname (__libmansuffix__). -.PP -When the __xservername__ server is started by the \(lqroot\(rq user, the config file -search locations are as follows: -.PP -.RS 4 -.nf -<cmdline> -.IR /etc/X11/ <cmdline> -.IR __projectroot__/etc/X11/ <cmdline> -.B $XORGCONFIG -.IB /etc/X11/ $XORGCONFIG -.IB __projectroot__/etc/X11/ $XORGCONFIG -.I /etc/X11/__xconfigfile__ -.I /etc/__xconfigfile__ -.IR __projectroot__/etc/X11/__xconfigfile__. <hostname> -.I __projectroot__/etc/X11/__xconfigfile__ -.IR __projectroot__/lib/X11/__xconfigfile__. <hostname> -.I __projectroot__/lib/X11/__xconfigfile__ -.fi -.RE -.PP -where -.I <cmdline> -is the path specified with the -.B \-config -command line option (which may be absolute or relative), -.B $XORGCONFIG -is the path specified by that -environment variable (absolute or relative), -.B $HOME -is the path specified by that environment variable (usually the home -directory), and -.I <hostname> -is the machine's hostname as reported by -.BR gethostname (__libmansuffix__). -.PP -Additional configuration files are searched for in the following -directories when the server is started as a normal user: -.PP -.RS 4 -.nf -.IR /etc/X11/ <cmdline> -.IR __sysconfdir__/X11/ <cmdline> -.I /etc/X11/__xconfigdir__ -.I __sysconfdir__/X11/__xconfigdir__ -.fi -.RE -.PP -where -.I <cmdline> -is a relative path (with no \(lq..\(rq components) specified with the -.B \-configdir -command line option. -.PP -When the __xservername__ server is started by the \(lqroot\(rq user, the -config directory search locations are as follows: -.PP -.RS 4 -.nf -<cmdline> -.IR /etc/X11/ <cmdline> -.IR __sysconfdir__/X11/ <cmdline> -.I /etc/X11/__xconfigdir__ -.I __sysconfdir__/X11/__xconfigdir__ -.fi -.RE -.PP -where -.I <cmdline> -is the path specified with the -.B \-configdir -command line option (which may be absolute or relative). -.PP -Finally, configuration files will also be searched for in directories -reserved for system use.
