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 ]

AVAILABILITY

SUNWkvm

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.  Resolution 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 description of how to reset the console device to the default value if it becomes unusable from programming an unsupported resolution. 

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 characters.  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.
