These settings are used to initialize the frame buffer device the next time the window system is run on that device. The persistence of these settings across window system sessions and system reboots is determined by the \fBxorg.conf\fR file. .sp .LP The second and third command forms display information, and do not alter the \fBxorg.conf\fR file. The presence of the \fB-help\fR and/or \fB-res\fR \fB?\fR options will cause any other option (not shown in the third form) to be ignored. .sp .LP You can configure only one frame buffer device at a time. To configure multiple devices, invoke the \fBfbconf_xorg\fR utility separately for each device. .sp .LP Only frame buffer device options can be specified with \fBfbconf_xorg\fR. Use the normal window system options to specify default depth (see \fBsvccfg\fR(1M)), default visual class, and so forth. Specify these as device modifiers on the command line. See\fI Xserver(1)\fR, part of the OpenWindows, not the SunOS, man page collection. .sp .LP You can specify which \fBxorg.conf\fR file to open. By default, \fBfbconf_xorg\fR opens the machine-specific file, \fB/etc/X11/xorg.conf\fR. Use the \fB-file\fR option to specify an alternate file. For example, the system-global file, \fB/usr/X11/xorg.conf\fR, can be opened instead. .sp .LP These standard \fBxorg.conf\fR files can be written only by the superuser or someone with the Primary Administrator role. Consequently, the \fBfbconf_xorg\fR program is run with setuid root permission. .SH OPTIONS .sp .LP The following options are supported for all frame buffer devices: .sp .ne 2 .na \fB\fB-defaults\fR\fR .ad .sp .6 .RS 4n Sets configuration options for the specified device to their default values.

If \fBmachine\fR is specified, the machine-specific \fB/etc/X11/xorg.conf\fR file is opened. If system is specified, the global \fB/usr/X11/xorg.conf\fR file is opened. The absolute pathname of a configuration file can be used instead. If the specified file does not exist and is to be updated, it will be created. The file system that will contain the \fBxorg.conf\fR file must be writeable by someone with superuser-like privileges. This option has no effect unless other options are specified.
