[SOLVED] Problem getting X to display on PVR 350 TV-out

[dougsnell]

I have TV-out working for "Watch TV" in Myth ... but X is still displaying on my monitor ... not my TV.

So, I figured I'd list a bundle of stuff out, see if anyone has any ideas. The one thing I did notice which seemed out of place is my /var/log/syslog has a line:

ivtv0-fb: Display size 640x400 (640x400 Virtual ) @ 8bpp

Not sure if that describes a problem, or is a reflection of the problem I'm having.

Here's my relevant lspci:

00:09.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 Encoder (rev 01)

Here's xorg.conf:

Here's hoping somebody out there knows what I'm looking at :)

[andrewb78]

Have you checked out the Gutsy HOWTO (https://help.ubuntu.com/community/MythTV_Gutsy_hardware_pvr-350_TV-out)? That might have a few answers.

Are you falling back to failsafe X on boot? Your xorg.conf actually shouldn't work in Gutsy. In the Device section for the PVR-350, use "ivtv" not "ivtvdev" for the driver. Also, how did you determine that your framebuffer was /dev/fb0? That may be correct, and looking at your dmesg I'm guessing it is, but what is the output of cat /proc/fb?

[dougsnell]

0 cx23415 TV out

... is from cat /proc/fb

That howto did the trick ... every search I've done turns up the Feisty or Edgy howto. Copying the xorg.conf right off that page and changing the PCI numbers did the trick for me.

I still have some tweaking to do as some things are a tad off the screen.

The last issue I'm having is one of a lack of sound. I'm running everything through default alsa. I'll have to do some more digging around ... but if you (or anyone else) has any suggestions, I would appreciate it.

Thanks!

[andrewb78]

Regarding things being off screen, see the (brief) discussion of overscan near the end of the Gutsy HOWTO. (The Gutsy HOWTO is only a couple days old, so it's probably not on Google yet.)

Regarding sound, are you trying to play sound through the TV? I don't think ALSA will do that (though if I'm wrong, I'd like to know how to do that). You can get the TV sound through the TV speakers by going to Utilities/Setup -> Setup -> TV Settings -> Playback. About the fifth screen is "Hardware Decoding Settings." Make sure "TV audio through PVR-350 only" is checked.

If you are instead trying to get your TV's sound through your regular sound card, you need to connect the audio out on the PVR-350 TV out to a line-level sound card input. I don't have it set up that way, so I don't really have more details.

[dougsnell]

Ah! :) Bingo.

I thought those cables were for input only (yes ... I know I connected the S-video cable to my TV, but for some reason I recall reading in the documentation that came with the card that the other cables were for input). I had considered changing things around, but hadn't gotten around to it.

TV is playing normally, now :) I'm thrilled ... and waiting for my wife to discover what's going on.
