help
This option gives you AGP support for the GLX component of the
XFree86 4.x on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850 and 860 chipsets.
XFree86 4.x on Intel 440LX/BX/GX, 815, 820, 830, 840, 845, 850
and 860 chipsets and full support for the 810, 815, 830M, 845G,
852GM, 855GM and 865G integrated graphics chipsets.
You should say Y here if you use XFree86 3.3.6 or 4.x and want to
use GLX or DRI. If unsure, say N.
use GLX or DRI, or if you have any Intel integrated graphics
chipsets. If unsure, say Y.
