LinHES Forums :: View topic - no tv out for me!

You are correct, this stuff is intended for display on a TV.

did you try the XF86Config-4.nvidia-tvout.sample file? it should be in the /etc/X11 directoty along with the XF86Config-4 file. backup the XF86Config-4 and copy the tv sample on top of XF86Config-4.

be sure to set the TVOutFormat correctly

Option "TVOutFormat" "SVIDEO"

or

Option "TVOutFormat" "COMPOSITE"

if you are using the svidio out on the card and using a converter to connect compsite to your TV, you probably want to use the COMPOSITE setting in the XF86Config-4 file of you might end up with a black and white picture.

very windows like in terms of setup ease!

Do you have a monitor hooked up also?

When the machine boots, both the tv and the monitor should be displaying the boot text.

If just the monitor displays anything when xwindows loads, and the tv goes blank at that point, then it's just a matter of what was posted above.

If you don't even get the boot text on the tv, and the monitor isn't showing anything ever, then there's a different problem going on.

OK, that didn't work, now I have NOO display at all. Boot sequence still shows on the monitor briefly, then nothing... Oh well Reinstall (again)

I've read "the pamphlet of Knoppmyth" but I must be missing something here. I've got an Nvidia Geforce4 Video card (old I know) with Svideo out and Composite (tv) out. But Myth wont use either. I can't find anything in the guide or the forums on this. Am I missing something?? I thought the point of this was to use myth on your Tv not monitor?? Or is there an undocumented config that I need to run to get Myth to output to my TV? I've been digging around and all I could find wat to edit xf86config-4. but that resulted in myth not loading at all! Help

Didn't see that file, but I will have another look. TV out has been so far my only disappointment. Everything else was easy to setup, and dar I say...very windows like in terms of setup ease!

You should be seeing at least the boot process on the tv, I believe, regardless of the linux configuration. Certainly the memory test happens before linux even starts to load. Is the cable to the tv correctly attached? Do you happen to have onboard video? What kind of video card are you using with what kind of outputs? What kind of tv is it and with how many different inputs? The tv tuner is normally set to 3 or 4, and the mythtv system is generally going on on channel 3 or 4, but I don't believe that could even be set before the boot process is finished, so you should see at least the boot process unless somehow something sets the outgoing channel before xwindows even starts.

Easier said than done. so far I've found the file, but 2 hours in and I still can make a backup of the original file. I find Linux command lines very frustrating. There's not real logic to the syntax I've found the Rename command. I'm tring to rename the oringal x686config-4 to .backup and then rename the nvidia sample to x686config-4 but I cannot figure out how to do this. Help!!

I think there are some linux tutorials on the wiki. but a couple commands are to rename or move a file Code: mv <originalFileName> <newFileName> to make a copy of a file, leaving the original intact Code: cp <originalFileName> <nameOfCopy> what I suggest you do is make a copy of the existing file Code: cd /etc/X11 cp XF86Config-4 XF86Config-4.backup then copy the tvout example on top Code: cp XF86Config-4.nvidia-tvout.sample XF86Config-4 For me, that just worked. depending on your connection S-Video vs. Composite, you may need to adjust the TVOutFormat line. to search for text in a file use grep Code: grep TVOutFormat XF86Config-4 the output of this command will probaby look like this: Code: root@mythtv:/etc/X11# grep TVOutFormat XF86Config-4 Option "TVOutFormat" "SVIDEO" If you are using s-video, you may be all set. if composite, you will need to change that line. search here or google for vi or nano for an editor

Thanx. I found the command just before I read your post. Who would have thought that the"rename" command isn't used to rename files! but you use MV instead!! Will give it a try and post back

Oh well Reinstall (again) Help First, before you re-install, see if you can telnet in (with putty.exe if you don't currently have an ssh telnet program), and rename the files back so you are using your old config file. Second, you may have a messup with your video cables, because you should be seeing something on your tv before it loads xwindows. Just seeing a blank even on bootup is suggestive of a problem there. Maybe you have your tv cable hooked to the onboard video, or perhaps you have your tv displaying the wrong input. (also, one thing to note is that if the tv has been receiving a signal it can't handle for a while, it could be temporarily messed up. Switch to another input and make sure it can still display regular tv. You might need to unplug it for a few minutes if it doesn't work.) Third, before you start messing with a lot of changes to the working config file, go back to the install instructions and check this piece out: "If you have an nForce chipset or any nVidia graphics card, and want to use its TV out capability, you may want to edit /etc/X11/XF86Config-4 and add: Option "ConnectedMonitor" "TV" "

Woohoo, Finally got it to work. Turns out that for some reason I can't use Composite out. Svideo works. Now on to the rest of it!
