NAME
       dexconf - generate Xorg X server configuration file from debconf data

SYNOPSIS
       dexconf [ options ]

DESCRIPTION
       dexconf	retrieves  values  from debconf(7)'s database and uses them to
       build an xorg.conf file.

       The information that dexconf uses is typically entered  via  a  debconf
       frontend	 (or  possibly in part by hardware autodetection tools).  Note
       that dexconf itself does not set any values in the debconf database; it
       only  retrieves them.  If configuration parameters of the debconf data‐
       base need to be changed, dpkg-reconfigure(8) should be used to do so.

       More experienced users should feel free to use  dexconf-generated  con‐
       figuration  files  as  a starting point for their customizations, since
       individual preferences vary greatly.

OPTIONS
       -h, --help
	      Display a usage message and exit.

       -o file, --output=file
	      By default, dexconf writes  to  /etc/X11/xorg.conf  This	option
	      instructs	 dexconf  to write to file instead.  Note that dexconf
	      unconditionally overwrites its destination file if it has suffi‐
	      cient access rights to do so.

ENVIRONMENT
       COLUMNS
	      This variable is used to format diagnostic messages so that they
	      fit the width of the terminal.  If not set, a terminal width  of
	      80 columns is assumed.

       TMPDIR dexconf  creates	a subdirectory of the directory name stored in
	      this variable, and uses that subdirectory as a scratch area.  If
	      not set, /tmp is used as the parent of the scratch directory.

OUTPUT FILES
       /etc/X11/xorg.conf
	      is the configuration file for the Xorg X server.

DIAGNOSTICS
       dexconf	produces  diagnostic  messages upon encountering various error
       conditions.  These messages are prefixed with the name of  the  command
       and a colon; for example:
	      dexconf: message
       A list of diagnostic messages currently issued by dexconf follows.

       This option, and XFree86 3.x output, are no longer supported.
	      dexconf  no  longer  supports  the -f, --format option.  See the
	      “HISTORY” section below.

       cannot create temporary work directory; dirname does not	 exist	or  is
       not a directory
	      dexconf  was  unable  to	create	a scratch directory to work in
	      because the parent directory (dirname) was not does not exist or
	      is  not  a  directory.   Create  dirname and set its permissions
	      properly, or set the TMPDIR environment variable to the name  of
	      an existing directory.

       cannot  create  temporary  work	directory  in  dirname;	 directory not
       writable
	      dexconf had insufficient permissions to create  a	 directory  in
	      dirname.	 Change	 the  permissions on dirname or set the TMPDIR
	      environment variable to the of a writeable directory.

       cannot generate configuration file; question not set
	      An answer to the indicated question was expected in the  debconf
	      database, but none was found.  dexconf cannot write a valid con‐
	      figuration file without this information.	 This problem  can  be
	      rectified	 by  reconfiguring  the	 X  server  package  with  the
	      dpkg-reconfigure(8) command.

       creation of temporary work directory dirname failed
	      dexconf was unable to create a scratch  directory	 (dirname)  to
	      work  in.	  This	diagnostic  is	only  issued after dexconf has
	      checked to ensure	 that  the  parent  directory  of  dirname  is
	      writable,	 and after the temporary directory to be used has been
	      removed (if necessary).  This diagnostic message could  indicate
	      that  something  on  the	system	is  attempting to use a tempo‐
	      rary-file race condition to compromise the system's integrity.

       error while getting options
	      dexconf received an error from  getopt(1)	 while	attempting  to
	      interpret	 the  command-line arguments.  Use only the documented
	      options.

       received signal; aborting
	      dexconf was sent a fatal signal; see the section on asynchronous
	      events below.

       this program does not know how to configure the package X server
	      dexconf  only knows how to write configuration files for XFree86
	      version 4.x X servers.  The value of the shared/default-x-server
	      debconf  template was set to a package name that dexconf did not
	      recognize.  A different tool will have to be used	 to  configure
	      the  selected  X	server, or dpkg-reconfigure(8) will have to be
	      used to change the default X server.

       unable to write to configfile
	      dexconf was unable to write to configfile because it lacked per‐
	      missions	to  do	so.  Run dexconf as a user with permissions to
	      write to configfile, or specify an alternate file to write  with
	      the -o or --output options.

       unrecognized option option
	      An  unrecognized	option was specified.  Use only the documented
	      options.

ASYNCHRONOUS EVENTS
       dexconf traps the HUP, INT, QUIT, and TERM  signals.   dexconf  removes
       its scratch directory and exits when it receives any of these signals.

EXIT STATUS
       0      A configuration file was successfully written.

       1      An  error occurred, or dexconf was interrupted.  See the section
	      on diagnostics above.

BUGS
       See the Debian Bug Tracking System ⟨http://bugs.debian.org/
       xserver-common⟩.	  If  you  wish to report a bug in dexconf, please see
       /usr/share/doc/debian/bug-reporting.txt or the reportbug(1) command.
