NAME
     cg14config - configure the cgfourteen device

SYNOPSIS
     /usr/platform/ platform-name  /sbin/cg14config  [  -d device
     ]  [ -r resolution ]  [ -g gammavalue ]  [ -G gammafile ]  [
     -u degammavalue ]  [ -U degammafile ]

DESCRIPTION
     cg14config sets up state on the selected cgfourteen  device.
     platform-name can be found using the -i option of uname(1).

     cg14config is supported only on Desktop SPARCsystems with SX
     graphics option.

     The interface, output, and command location are  uncommitted
     and subject to change in future releases.

OPTIONS
     -d device
           Use device as  the  cgfourteen  device  to  configure.
           Default is /dev/fb.

     -r resolution
           Use resolution as the desired screen resolution. Reso-
           lution  is  specified  in  terms  of  screen width and
           height (in pixels),  and  vertical  refresh  (in  hz).
           Available resolutions are:



           1024x768@60
           1024x768@66
           1024x768@70
           1152x900@66
           1152x900@76
           1280x1024@66
           1280x1024@76
           1600x1280@66
           1920x1080@72


     The default is the value read from the monitor sense  codes.
     Note  that  some  or all of the resolutions above may not be
     supported by any given monitor. If a  programmed  resolution
     is   outside of the range of allowable values for a monitor,
     unpredictable results can occur,  including  damage  to  the
     monitor.  Thus,  care  should  be taken when programming the
     resolution. See  Openboot Command Reference for  a  descrip-
     tion of how to reset the console device to the default value
     if it becomes unusable from programming an unsupported reso-
     lution.
           The -r option is not available when the window  system
           is running.

     -g gammavalue
           Each entry of the gamma lookup table  will  be  loaded
           with entry^(1/gammavalue).  The gamma lookup table has
           256 entries. Default  gammavalue is 2.2.

     -G filename
           Initialize the gamma lookup table with the contents of
           filename. The format of
            filename is 256 triplets (red  green  blue)  of  non-
           negative integers separated by NEWLINE characters. The
           integers must be in the range 0 to 1023, inclusive.

     -u degammavalue
           Each entry of the degamma lookup table will be  loaded
           with  entry^(degammavalue).   The degamma lookup table
           has 256 entries. Default degammavalue is 2.2.

     -U filename
           Initialize the degamma lookup table with the  contents
           of   filename.  The format of  filename is 256 entries
           of  non-negative integers separated by NEWLINE charac-
           ters.  The  integers  must  be  in the range 0 to 255,
           inclusive.

EXIT STATUS
     cg14config returns 0 on success and a  positive  integer  on
     failure.

     1     Selected device is not a cgfourteen device.

     2     Requested action failed.

     3     Unsupported resolution.

     4     Gamma or degamma value out of range.
