The following list explains how to change the defaults.
The X11 pipeline is the default pipeline for Oracle Solaris and Linux. Change this default as follows:
-Dsun.java2d.opengl=true Attempt to enable the OpenGL pipeline.
The use of DGA is controlled as follows:
NO_J2D_DGA unset Use DGA, if available.
NO_J2D_DGA set Disable the use of DGA.
MIT Shared Memory Extension (SHM) is controlled as follows:
To use SHM, if available, specify either one of the following properties:
NO_J2D_MITSHM unset
J2D_USE_MITSHM=true
To not use SHM, specify either one of the following properties:
NO_J2D_MITSHM set
J2D_USE_MITSHM=false
The general use of pixmaps is controlled as follows:
-Dsun.java2d.pmoffscreen unset Use pixmaps if DGA is not available.
-Dsun.java2d.pmoffscreen=true Force the use of pixmaps.
-Dsun.java2d.pmoffscreen=false Disable the use of pixmaps.
The use of Shared and Server pixmaps is controlled as follows:
J2D_PIXMAPS unset Use both types.
J2D_PIXMAPS=shared Use only shared memory pixmaps.
J2D_PIXMAPS=sserver Use only server-side pixmaps.
The choice of default visual is controlled as follows:
FORCEDEFVIS unset (default) Use the best visual available.
FORCEDEFVIS set to a hexadecimal value Use the visual whose ID is the hexadecimal value.
FORCEDEFVIS set to any other value Use the default visual.
