Hello all.
I'm doing this in Kubuntu 10.04 with Zoneminder 1.24.2.

I have a bt878 card that's doing everything but showing me video. (It's only showing a black screen.) In short, the text on the zoneminder main page is green and looks like everything should be working. However, after clicking on the monitor, it does give me a frame-rate (12.90 per second) and no errors.....that I can see anyway. So, yes, it's behaving as if it's working just fine it's just that the output is black.

I have a similar card that works just fine in on another box using Ubuntu (not Kubuntu as in the non-working version) 11.04 using the same version of Zoneminder.

I've followed the instructions here:
http://bytebasket.com/index.php?option= ... &Itemid=76
......and created a bttv.conf under modprobe.d with the following text:

Code: Select all

alias char-major-81 bttv
options bttv card=77 tuner=4 radio=0 triton1=0 vsfx=0 autoload=0

For what it's worth, the working card (in the other computer running 11.04 Ubuntu) I created a modprobe.conf under /etc/ with the following text:

Code: Select all

options bttv card=77 tuner=4 radio=0 triton1=0 vsfx=0 autoload=0

I tried^^ that in the non-working one but it didn't work either. Same issue.

Oddly enough, in the working version lshw gives me this (notice the differences in the 'latency' bit):

Code: Select all

sudo lshw | grep bttv
                configuration: driver=bttv latency=132 maxlatency=40 mingnt=16card

In the non-working/black-screen-only version, the same command gets me this:

Code: Select all

aaron@George:~$ sudo lshw |grep bttv
                configuration: driver=bttv latency=66 maxlatency=40 mingnt=16

So perhaps the cards are different? Perhaps there's some glaring error here that I'm not picking-up on?

Here's the dmesg from the non-working one:

Huh.

Interesting.

Here's the output of 'proc/interrupts' on the box with my working card (different hardware and software. This box runs 11.04 Gnome on some sort of HP.)

Here's the output of proc/interrupts from the non-working version (running 10.04 KDE on ?? hardware):

From looking at each one's respective dmesg output it appears that there's something funky with the IRQ. Check out the non-working IRQ stuff within the dmesg:

aaron@George:~$ dmesg |grep bttv

[ 107.708248] bttv0: PLL can sleep, using XTAL (28636363).

Does it seem like I may be on to something here?

Is ata_pixx, and/or uhci_hcd:usb4 causing some sort of a race condition so that bttv0 isn't getting "picked-up"?

Looks like I'm getting some sort of "success" message with this in the working one, no?
[ 28.630989] bttv 0000:01:00.0: PCI INT A -> Link[LNKD] -> GSI 11 (level, low) -> IRQ 11

Not so in the non-working one:
[ 24.548979] bttv 0000:05:09.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18

Notice the "Link[LNKD]" bit in the working one? Where is it in the non-working one?

I wonder if simply upgrading to 11.04 on the non-working box would fix the whole thing?

Or is there a way to manually set IRQ's?

My brain officially hurts now.

Thanks for any advice!

I ended up installing 11.04 (standard gnome ubuntu.....not kubuntu) then upgrading to 11.10 immediately after and decided to try things out.

....and things work! Same video card and everything. I did reset my BIOS to its default settings but I don't feel like that was the culprit since I did that when trying to install zm on 10.04 kubuntu as well.

Here's my output of /proc/interrupts

I should note that I'm also using zoneminder 1.24.4 now. Just did an apt-get on it.

Zoneminder is awesome when it works.
