G400 & OpenGL

[G400SG16mb]

Hi.

I've installed Matrox Powerdesk 6.82.0216. It says under information that OpenGL ICD 2.57.057 is installed. But OpenGL isn't working at all.

What do I need to do to make OpenGL work with my Matrox G400? I had used GLSetup the last time, but it is defunked now.

have you removed all instances of GLsetup? Have there been anyother cards installed in this machine?

BTW GLsetup should never have been used

that was a while ago, the hard disk has been formatted since then.

I've been previously using a Matrox Millennium 1, and onboard video before that. Onboard is deactivated, and the PCI MM1 has been removed.

You must have a hardware IRQ set to the card in the motherboard BIOS (prefferably IRQ9, 10 or 11).
Your desktop must be set to 16bit or 32bit color. Won't work at 24bit.

[G400SG16mb]

Desktop is at 32bpp, the video card is running on IRQ 11 according to the Help and Support program.

I didn't see anything in the Bios settings about assigning IRQs to cards.

[Kruzin]

There should be an option for "assign IRQ to VGA" in there somewhere.

[G400SG16mb]

No, there is abosolutely nothing like that in there. The McGee's Alice demo gives "GLW_StartOpenGL() - could not load OpenGL subsystem" when trying to start.

Direct3D works fine, so I doubt it's hardware damage.

Are you using dualhead?

I think his nick answers that...

SG stands for surround gaming right?

[G400SG16mb]

SG ram is a type of SD ram for video cards

It's a single display version. I got this card when they first came out (it is even an AGP 2x). The more expensive G400 versions were double the price at the time.

Well, he coulda had one of those upgrade daughterboards.

Ok, in Celestia, under OpenGL Driver Info, it says:

Vendor: Microsoft Corporation
Renderer: GDI Generic
Version: 1.1.0

And OpenGL mode won't work in Homeworld.

So the actual Matrox OpenGL driver isn't activated? Any tips on how to do this?

[G400SG16mb]

I tried the Matrox powerdesk removal utility, and reinstalled Powerdesk. But it still doesn't work.

The Matrox OpenGL .dll file is installed and referenced in the Windows registry.

Could it be because I've got DirectX9 installed? It'd be no small task to install DirectX 8 now.

do you have busmastering enabled on the G400? It needs busmastering for both OpenGL and DVDMAX functionality.
