TV-out does not work on HP Compaq nx6325 notebook with the infamous
RS482 (Radeon Xpress 200M) video card (yes, I know that Xpress chips are
not well supported).

The output looks like a black screen with some noise which changes
depending on what is displayed on LCD screen, so I guess it does output
something, but not correctly.

I am using xrand to enable TV-out:

xrandr --addmode S-video 800x600
xrandr --output S-video --mode 800x600

Although the cable is connected, it insists that it is not:

Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 1400 x 1200
VGA-0 unknown connection (normal left inverted right x axis y axis)
   1280x800       60.0
   1280x768       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9
LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis)
305mm x 228mm
   1400x1050      60.0*+
   1280x800       60.0
   1280x768       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9
S-video disconnected 800x600+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
   800x600        60.3*

I thought this was related to PAL/NTSC, but setting the TV standard via
xrand changes nothing:

xrandr --output S-video --set tv_standard pal

I don't know whether TV output on RS482 has been tested. But FWIW, load
detection
of the TV output is disabled by default (it creates some problems in
some cases). That's
probably why xrandr says S-video is disconnected. To reenable TV load
detection (and
maybe get xrandr to report S-video as connected), try:
    xrandr --output S-video --set load_detection 1

Just tested with 1:6.7.198~git20071223.ad3325f6-1, and it has only got
worse, I am afraid. The "load_detection" option makes absolutely no
difference, and now I cannot enable S-video at all:

 $ xrandr --addmode S-video 800x600
 $ xrandr --output S-video --mode 800x600
 xrandr: cannot find crtc for output S-video

 $ xrandr --output S-video --mode 800x600 --crtc 0

Your VGA-0 output is marked as unknown (load detection on Xpress 200
board doesn't work well yet), it's using the second CRTC (the hardware
pipeline in the board).  The internal panel (LVDS) uses the first CRTC.
So there is no CRTC available for S-video (only 2 are available for all
outputs).

You should disable VGA-0 so that one CRTC becomes available. If you
don't care at all about the VGA output, you should just add:
    Option "Monitor-VGA-0" "Foo"
to the Device section and add the following section above:
    Section "Monitor"
    Identifier "Foo"
    Ignore "true"
    EndSection

The upstream developers are well aware of this bogus load detection on
Xpress fortunatelly (that's why it says "unknown" in stead of a vague
"disconnected" as earlier). There are some other bug reports about this.
So I hope we can expect some fix soon.

Guys,

Do you still have problems with multihead on your Xpress 200 board? If
so, can you try 6.12.5 in unstable or 6.12.191 in experimental with KMS
and a recent kernel?

thanks

I finally got a chance to play around with multihead on Xpress 200 based
laptop. I am using KMS with Gallium from xorg-edgers repository on
Debian Sid/Experimental.

I was trying to get S-video output to work with KMS, but failed. TV
screen remains largely empty and black, but with slight noise here and
there. In other words, no luck.

When I switched to UMS, I was able to get S-video output working after I
disabled and enabled it for the second time. I got garbled screen the
first time. Other than that, it does seem to work just fine. Just
finished watching a movie, and noticed no problems with the picture.

I currently do not have a way to test VGA output.
