nVidia has their own OpenGL implementation, which isn't compatible with DRI (known as NV-GLX). So, you could have 3D on the GeForce2 MX (with the closed-source driver, the open nv driver is 2D-only), but that would nuke DRI on the G450 and the Radeon. The flipside is that you could have DRI on the MGA and ATi, but not the GeForce2.
The following chipsets support DRI: ATi Radeon 7500 ATi Radeon DDR ATi Radeon SDR ATi Radeon VE ATi Rage 128 Pro ATi Rage 128 3dfx Voodoo5 3dfx Voodoo4 3dfx Voodoo3 3dfx Voodoo Banshee Matrox G450 Matrox G400 Matrox G200 3DLabs GMX 2000 Intel i810 (i815/i830 also, IIRC) The TNT, TNT2, GeForce, GeForce2 and GeForce3 series support nVidia's NV-GLX, which overwrites the DRI OpenGL libraries (libgl.so, etc) -----Original Message----- From: Lee Stoltz [mailto:[EMAIL PROTECTED]] Sent: Wednesday, November 14, 2001 12:04 AM To: [EMAIL PROTECTED] Subject: Re: [Newbie]Multiple displays "Sprague, IT3" wrote: > > Might wanna go with 2 MGAs instead, unless you want OpenGL issues (the > GeForce2 MX only has dualhead support with the nVidia binary drivers, which > stomp on DRI, meaning that the G450 and Radeon VE won't do HW-accelerated > GL.) However, I see no reason why multiple g450's wouldn't work. > Yeah, you're probably right, but what fun would that be? *grin* I probably wouldn't mind solely having g450's except that the 3d performance isn't as good, and they have less memory. Actually, I haven't really messed with DRI at all yet. That's probably the next thing I should work out. Will the nv and the tdfx driver both support DRI simultaneously? Does nvidia have their own 3D setup or something? I couldn't imagine that they'd go without 3D hardware acceleration. Is anyone working on open source dual head drivers? _______________________________________________ Newbie mailing list [EMAIL PROTECTED] *** To unsubscribe , or change message options, see: http://XFree86.Org/mailman/listinfo/newbie _______________________________________________ Newbie mailing list [EMAIL PROTECTED] *** To unsubscribe , or change message options, see: http://XFree86.Org/mailman/listinfo/newbie
