fbconfig is the generic command line interface to query and configure frame buffer attributes.

The following form of fbconfig is the interface for the device independent operations performed by fbconfig:

fbconfig [-list | -help]

The following form of fbconfig is the interface for configuring a frame buffer:

fbconfig [-dev device_filename] [-prconf] [-propt] [-res]

If the -dev option is omitted, the default frame buffer (/dev/fb or /dev/fb0) is assumed. In the absence of specific options, the response will depend upon the device specific configuration program and how it responds to no options

The following options are supported:

-dev device_filename

Specify the FFB special file. The default is /dev/fbs/ffb0.

-help

Print the fbconfig command usage summary. This is the default option.

-list

Print the list of installed frame buffers and associated device specific configuration routines.

Device Filename Specific Config Program --------------- ----------------------- /dev/fbs/ffb0 SUNWffb_config /dev/fbs/ffb1 SUNWffb_config /dev/fbs/m640 SUNWm64_config /dev/fbs/cgsix0 not configurable

-prconf

Print the current hardware configuration.

-propt

Print the current software configuration.

The following operands are supported:

device_specific_options

device_specific_options are specified in the format shown by the -help output, or the corresponding device-specific man page.

See attributes(5) for descriptions of the following attributes:

afbconfig(1M), ffbconfig(1M), attributes(5)

Because of limitations in the m64 kernel driver and related software, fbconfig (with the -prconf option) is unable to distinguish between a current depth of 24 or 8+24. The -propt option returns the depth specified in the OWconfig file, which will be in effect following the next restart of the window system. The xwininfo utility, usually shipped in the package containing frame buffer software (such as SUNWxwplt), reports current depth of a specified window.
