Hello list,
I've now been fighting for 2 weeks with my new Mythbox and specially with getting the stuff on the TV over the TV output of the PVR 350.
I succeeded in getting the Live TV working, but I can't find the solution allowing to also get the Mythtv menus on the television.
What I did/tried:
-loading ivtv-fb with the osd-...=1 Option
-loading fb at boot in order to get ivtv on fb1
-modifying my xorg.conf as explained at: http://www.ivtvdriver.org/index.php/Howto:XDriver or other very similar places.
down you can see my actual file. There are no errors in the logs *neither dmesg nor xorg.0.log. I only could find warnings about the "module"-section with messages like "will not load v4l. Module not loaded if not loaded at another place" or something like this.
At boot, the machine is working about one minute. during this time, the screen is black and the tv is flattering 2-3 times: something seems to go through the wires. After this an error message appears that there is no good x-configuration and I get the possibility to continue (over a fall back solution of ubuntu ?) or to configure manually. I am wondering that I can't find anything about this event in the logs... I had a look at dmesg and xorg.0.log... some hints for better places where to search ?
What I don't really understand here is that Google only shows me people using this option in order to eliminate the black screen in the middle of the picture. On my configuration, I can either NOT LOAD ivtv-fb and get a good result with: cat myfile.mpg > /dev/video16 and no LiveTV or LOAD ivtv-fb and see LiveTV, with online menus, and Mythtv on the graphic card... but with this configuration, If I try the Cat... video16 -stuff, I have got the black square in the middle of the picture.
Among the different things I have been able to read, I couldn't find anything about this problem... maybe it is not THE problem, an I am missing something ????
The last thing that might be linked to this whole story is that I don't have any terminal anymore on the computer display: CTRL+ALT+F1 through F7 shows only a black screen. I could imagine, that one of these blacks screen has something to do with the black square in the middle of the cat myfile.mpg > /dev/video16...
This was a quite long story, I hope there are enough details to make it possible to solve the problem. Pleas don't hesitate, if you need further informations !
many thanks in advance to everyone who can help!
Simon
