right after you boot up and see the lines,
(with the lines visible on the screen) run this:
#!/bin/bash grep modesetting /var/log/kern.log > vid grep Modeline /var/log/Xorg.0.log >> vid xrandr >> vidand then show us "vid"
As I said before, troubleshooting this is a pain, because the problem goes away until the system "sleeps" the vid output. However, I was able to check it this morning.
I did a "tail -F Xorg.0.log", and hit return a couple of times to give me some spacing between old output and new. Then I turned on the TV. When it did it's sync up, this is what was written to Xorg.0.log...

Here's the output of xranr. (I didn't think to run that command before I'd fixed the refresh after doing the above. I'll try it again tonight to see if it changes when it is screwed up.
