Chapter 6. Software Application Considerations

This chapter discusses operating system tasks related to the POWER GXT800P
graphics adapter.

Starting the Server in Overlay and Color Planes

The X server can create windows in a separate set of frame buffer planes called
overlays. The X server supports this by defining distinct visuals for the overlay and
color planes.

The -layer n parameter for xinit gives the system the ability to select the hardware
frame buffer planes in which to run the X server. A value of:

0 indicates the color plane.
1 indicates the overlay plane (default).

These are the only valid choices. All other choices will default to layer 1.

Starting the X server in the color planes

API Required Parameters

Following are xinit options that take advantage of 3D hardware capabilities. These
options are required to run the 3D application programming interfaces (APIs).

API for PEX:  

Starting the X server for the PEX API requires an additional

parameter

 -x pex

. For example:

xinit -- -x mbx -x abx -x pex 

<

other flags

>

API for OpenGL:  

Starting the X server for the OpenGL API requires an additional

parameter

 -x GLX

. For example:

xinit -- -x dbe -x abx -x GLX 

<

other flags
