 |
|
I've done some extensive system upgrades recently, and I'm hoping someone can help me figure out exactly what I did to break my TV tuner.
I've got a Hauppage TV tuner, and it's worked fine for quite some time. Recently, I upgraded my kernel (to 2.6.11-gentoo-r9), upgraded to X.org rather than XF86, and started using the nvidia drivers with TwinView. (I'd gone quite some time without using my second monitor.)
Starting xawtv gives me this error:

I've tried starting it with -noxv, or -nodga, or both, but it still won't work. This might be a simple fix: I just don't know a whole lot about X.
My /etc/X11/xorg.conf, in case it matters:

(I just tried adding the "Option XVideo" bit in a (fruitless) attempt to get it to work.)
The system does "see" the card, as this bit from phpsysinfo shows:

I'm sure that, somewhere along the line, I broke something that's needed. But can someone steer me towards figuring out what it was? |

I use MythTV, don't know if xawtv has different requirements...
Make sure you still have BTTV in your new kernel.
Here's what's in my /usr/src/linux/.config

CONFIG_VIDEO_BT848=m
CONFIG_VIDEO_BTCX=m

Hmm, looking at your error message again, I found this in my xorg.conf
| Quote: |
# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
SubSection "extmod"
Option "omit xfree86-dga" # don't initialise the DGA extension
EndSubSection
Load "extmod"
|
Not sure if that helps, but hope it does. |

Since the last baselayout upgrade my kernel modules don't load automatically, so I'm not able to use my webcam or tv tuner without loading them myself, and this could be your trouble. Look at your kernel config If you have bttv ( Devices->Multimedia->Video for Linux->BT848 ). If you have it marked as a module try
and then xawtv. If this works you have the same problem I had. Then, you have two choices
1. Put bttv in /etc/modules.autoload.d/kernel-2.6 ( assuming you are using kernel 2.6). This will work but you'll have to do so for some other modules ( like ide-cd if you have this as a module ) and perhaps you don't know which ones.
2. The easy way is coldplug. It'll load all modules for your hardware and you won't need to know their names or what are they needed for. Just do
| Code: |
emerge coldplug
rc-update add coldplug default
