The SUNWifb_config utility is specific to Expert3D; it cannot be used with any other frame buffers. You can use the SUNWifb_config utility to:
Specify a different screen resolution
Type of visuals (linear or nonlinear
Whether to use 8-bit pseudocolor visual (overlay visual)
Whether linear visuals will be reported before their nonlinear counterparts in the screen visuals list
How to set the default screen visual
How OpenGL visuals will be supported
Specify whether Server Overlay Visuals (SOV) will be available
Enable slave mode so that the video from this frame buffer will be synced with the video of the display that is connected to it
Enable stereo mode
Enable frame buffer memory to be allocated for accelerated accumulation buffer for windows
Configurable gamma correction by specifying a gamma value or a file containing a gamma-correction table
