I've also posted this in the hardware section as it probably gets more traffic. I've searched the forums and have been trying for two days now to edit xf86config-4 file through various methods and it just won't work.

Libranet is working great (smooth graphics) but won't enable the second monitor.

I've tried xf86cfg and xf86cfg -textmode but don't know the exact specs of the desired hardware.

I'm using a Dell D1226H 19" monitor on an ATi Radeon 64Mb VIVO agp card (both detected fine and working) and an Optiquest Q71-2 17" monitor connected to a Matrox Millenium II video card (4Mb).

It's the Optiquest and Matrox that I have no luck with.

If I replace the Libranet xf86config-4 with a Xandros version from an old installation, I do get both monitors working but the graphics are very choppy. I assume that it's because DRI isn't enabled.

If I copy and paste the DRI text into the Xandros version, it doesn't make a difference and if I copy and paste the relevent device, monitor, screen and layout information into the Libranet generated version of xf84config-4 it causes an error.

So the question is:
1) Can DRI be enabled on a dual monitor setup?
2) If so, is the low video RAM on the Matrox causing the problem (Is it possible to have DRI enabled on only 1 of the 2 cards?)
3) How do I get my xf86config-4 file configured correctly? (As in how do I correctly select the model type, pci bus#, etc and resolution for my Matrox and Optiquest.)

I can post files if requested.

Thanks,
