I am willing to test any patches/configs to help with this one.
Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

X log without xorg.conf
Without xorg.conf my system hangs completely and I need to power cycle the
machine. And no TV output either.

tv-out support is pretty experimental so far, so I'll see what I can figure out
Thanks for looking into this. I noticed the experimental state of tv-out support
but just wanted to make this bug for reporting how it works.
Actually there's an upstream bug report so I think this one can be closed.
I agree, this should be resolved upstream first. We will continue to track the
issue in the centralized upstream bug tracker, and will review any bug fixes
that become available for consideration in future updates.
Thank you for the bug report.
The upstream bug mentioned is not the same : it is about garbled TV output.
With mobility x700 (I have one too), there is no TV-output at all. The driver doesn't even know about TV-output according to xrandr:
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 4096 x 4096
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
800x600 60.3 56.2
The laptop hardware is the same (different brand though) as the one
in this bug report :

My graphics card has exactly the same video bios rom as the one
attached in the report in
I have DRI2 and KMS working.
I would like to report this bug upstream, but where should I report it
(kernel (KMS), xorg...)?
