you guys are absolutely right, I think I got some kind of misconception
of how X works. So my apologies especially to, Alex. I tried what you
suggested in your last mail and it worked.
That is I disconnected everything but the TV. The TV was switched on but
I zapped to another channel so that I didn't have to see the garbage
during the boot process.
Then I blindly logged in and called the tv-out script. After the sound
began to play I switched the TV to AV1 and that's it -- I got a picture
(and a really nice one, too).
So now I know that it works. But allthough the picture is great this I
would like to be able to access my flat panel. I'm now trying to play
with "CRT,CRT" and tricking the X server a little. :)
If you got any ideas I'd appreciate to hear them.
