the GVX420 uses GLINT R4 rasterisers and GLINT Gamma 2 geometry
the `glint' driver supports GLINT Gamma, GLINT MX, GLINT 500TX. It doesn't
specifically say that it supports the GLINT R4, but I am using a
GVX1 on my home computer which uses GLINT R3 rasteriser and GLINT Gamma 1
geometry processor, and it works beautifully with the `glint' driver.
This suggests it will work for the GVX420.
From the looks of it, the GVX420 uses two separate graphics processors,
which are accessible individually by Xfree86. You actually configure two
"device" entries, one for each chip. Then you can use Xinerama to set up
the dual monitors so that the two monitors act as a single huge
I have some jpeg scans of a `Maximum Linux' article describing how to do
dual monitors with both dual graphics cards and dual-output agp cards.
There are four images, for about 10MB for the group. If you want, I can
put them up for download. I think you will find that the article will
answer all your questsions re: dual monitor xfree86 configuration.
Let me know by email if you want these scans.
