C.3.3.9. The DRI section
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 is rarely used, as the DRI Group and Mode are automatically initialized to default values. If a different Group or Mode is needed, then adding this section to the
xorg.conf file will override the default values.
The following example shows a typical
DRI section:
Section "DRI" Group 0 Mode 0666 EndSection
Since different video cards use DRI in different ways, do not add to this section without first referring to http://dri.freedesktop.org/wiki/.
Where did the comment section go?
