xserver has no DGA support - /dev/video0 No such file or dir

I recently ordered and installed a pci card for use with zoneminder (ordered from bluecherry, so I am sure it is compatible)- I believe it uses the BTxxxx(forget exact)? drivers. I am running gentoo, and have installed a stable zoneminder.

Here is what I get when running xawtv:

zoneminder@gentoo1~> xawtv
your xserver has no DGA support
can't open /dev/video0
v4l-conf had some trouble, trying to continue anyway...
v4l2: open /dev/video0: No such file or directory
v4l2: open /dev/video0: No such file or directory
v4l: open /dev/video0: No such file or directory
no video grabber device available

I would like to know what kernel options I need to enable and what other tests I should run... Can someone point me in the right direction?
TIA

I've done some research and some tweaking but I'm still not getting a picture....

Here is what I have done:
recompiled my kernel, enabling everything I could find related to v4l1 or v4l2 and anything starting with bttv or bt848

I disabled the ivtv module I had loading.
I enabled all the bttv and bt848 modules...

Now using nvidia proprietary drivers with glx and dga.

Here's what I get now when I try xawtv as root:

Code: Select all

root@gentoo1~>xawtv
This is xawtv-3.95, running on Linux/i686 (2.6.23-gentoo-r8)
xinerama 0: 640x480+0+0

Sorry to triple-post, but I am making little progress and would really like to get a working zoneminder to see what it's all about.

Let me summarize and ask one or two specific questions:

I've been focusing on getting video to display on my Xserver. I am sure the cameras work; I am sure the card is bttv.

The tool I've been using is xawtv, as I thought this program was specifically for the bttv drivers, but all I am getting is a blank screen.

Is there a good resource for exactly what kernel options need to be compliled?

I know my cameras work, how do I know they are detected / connected properly?

What diagnostics tools can I be using instead of xawtv? Is there a command output that would be useful to post here?

Thanks for your time
