This driver detects video modes available for use by io-graphics. The devgt-iographics driver loads hardware-specific DLLs, and calls into the DLLs in order to obtain mode information. The mode information is sent to standard output, and consists of a list of commands that will launch the graphics subsystem (io-graphics). The devgt-iographics driver is typically launched by crttrap.
