NAME

gtconfig − initialize the GT Graphics Accelerator and download microcode

SYNOPSIS

/usr/sbin/gtconfig [ −d device-filename ] [ −f filename ] [ −s0 filename ]

[ −s1 filename ] [ −I microcode-directory ] [ −E bit-code ] [ −g|G gamma-value ]

[ −degamma8|DEGAMMA8 on|off ] [ −i ] [ −m|M monitor-type ] [ −c 1-14 ]

[ −w 2-9 ] [ −v ]

DESCRIPTION

gtconfig initializes the GT Graphics Accelerator and downloads microcode from the host.  It is normally run as a part of /etc/init.d/gtconfig to download GT microcode files and to complete GT initialization. 

The standard version of the file /etc/init.d/gtconfig contains the following gtconfig command line:

/usr/sbin/gtconfig

If another configuration is desired, edit the command line in /etc/init.d/gtconfig

It is inadvisable to run the gtconfig command while the configured device is being used; unpredictable results may occur.  If it is necessary to change the gtconfig command, bring the system down gently, boot single user, edit the gtconfig line in the /etc/init.d/gtconfig file, and bring the system back up multi-user. 

Filenames may be either relative or absolute pathnames.  Relative pathnames are prepended with the path specified by −I, or the default path /usr/lib. 

OPTIONS

−d device-filename
Specifies the GT special file. The default is /dev/gt0. 

−f filename
Specifies the Front End microcode file. The default is gt.ucode. 

−s0 filename
Specifies the Setup Processor 0 microcode file. The default is gt.c30.ucode. 

−s1 filename
Specifies the Setup Processor 1 microcode file. The default is gt.c31.ucode. 

−I microcode-directory
Specifies the directory containing microcode files. The default is /usr/lib. 

−E bit-code
Initializes the cursor enable plane to contain all zeros or all ones.  The default is 0. 

−g gamma-value
Specifies the gamma correction value. The default is 2.22.

−G gamma-value
Loads the gamma correction table only; does not initialize the GT or download microcode.

−degamma8 on|off
Specifies automatic inverse gamma correction of 8-bit indexed color maps.  This allows colormaps with built-in gamma correction to work properly on GT.  The default is on. 

−DEGAMMA8 on|off
Like degamma8, but only specifies automatic inverse gamma correction; does not otherwise initialize GT or download microcode.

−i Initialize the GT backend. 

−m monitor-type
Specifies the monitor type of 1280_76, 1280_67, or stereo. The
 
default is 1280_67.

−M monitor-type
Sets the monitor type only; does not initialize the GT or download microcode.

−c 1-14
Sets the OpenWindows server CLUT quota. The default is 8. 

−w 2-9
Sets the OpenWindows server WID plane quota. The default is 5. 

−v Sets verbose mode.
