gtconfig - initialize the GT Graphics Accelerator and download microcode.

---

SYNOPSIS

DESCRIPTION

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

The standard version of the file /etc/rc.local contains the following gtconfig command line:

/usr/etc/gtconfig

If another configuration is desired, edit the command line in /etc/rc.local.

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/rc.local 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.
