(WW) NVIDIA: No matching Device section for instance (BusID PCI:0:3:5) found

What does it mean? This is an ASUS P5N7A-VM with 9300 IGP.

# lspci
00:03.5 Co-processor: nVidia Corporation MCP79 Co-processor (rev b1)
        Subsystem: ASUSTeK Computer Inc. Device 8356
        Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 11
        Memory at f9580000 (32-bit, non-prefetchable) [size=512K]

And what's this:

(WW) NVIDIA(0): 32-bit ARGB GLX visuals require the Composite extension.
(WW) NVIDIA(0): Disabling 32-bit ARGB GLX visuals.

... running 64bit Debian Testing.

Also, how can I update the video BIOS?

That "Co-processor" device doesn't look like a graphics device. I don't know why your X server thinks it is one. You can just ignore that message.

As for the 32-bit ARGB visual thing, you can't have 32-bit visuals without the Composite extension, just like the message says. If you don't have the Composite extension enabled, that's expected. See the README for more information.

For updating the VBIOS, please contact your graphics card vendor.

OK.

I believe I must have Composite disabled for VDPAU, to stop tearing, right? This is what I've always been told.

Hm, Asus doesn't have a video bios update, although I know there is one...

[AaronP]

Since you didn't post a bug report, I can't tell what you have in xorg.conf but if you didn't explicitly set "AddARGBGLXVisuals", then that message is just informational and not a warning -- if you disable the Composite extension, which as you mentioned is currently necessary to get the VDPAU overlay presentation queue, then it's expected that you won't get 32-bit ARGB visuals. If you didn't specify "AddARGBGLXVisuals" and it's still printing those messages out as (WW), then that's a bug and I'll look into changing to (II).

If you bought your graphics card from Asus and Asus doesn't have a video BIOS update available, then there is no video BIOS update for your card.

Thanks Aaron.

With the current driver, is any of this unnecessary now?

EDID has never seemed to work no matter how new or expensive my projectors are. I know X now autosizes quite effectively, but I really want pixel perfection through to the display.

I see now why ARGB GLX visuals is coming up as a WW; as I'm disabling Composite maybe there's no sense in trying to enable it?
