The GX is an 8-bit indexed color graphics accelerator, specializing in 2D and 3D wireframe, flat-shaded polygon, and general window system acceleration. Window system acceleration is automatic; you can access other acceleration features through Solaris graphics APIs. Several 8-bit visuals are supported, and the built-in default visual is 8-bit PseudoColor. The GX is available for SBus and P4 bus.
The GXplus device is similar to the GX with additional memory that can be used for double buffering and expanded screen resolution on SBus systems. The Solaris X server uses the GXplus to automatically accelerate X11 pixmaps by using offscreen storage whenever possible.
