DRI

The optional DRI section specifies parameters for the Direct Rendering Infrastructure (DRI). DRI is an interface which allows 3D software applications to take advantage of 3D hardware acceleration capabilities built into most modern video hardware. In addition, DRI can improve 2D performance via hardware acceleration, if supported by the video card driver.

This section rarely appears, as the DRI Group and Mode are automatically initialized to default values. If a different Group or Mode is desired, then adding this section to the xorg.conf file will override those defaults.

The following example illustrates a typical DRI section: 

Article "DRI"
 Group        0
 Mode         0666
EndArticle

Since different video cards use DRI in different ways, do not add to this section without first referring to .
