Hi All
Happy news ... :) .... :
At least with the very latest xorg packages on Debian unstable/powerpc
software is getting installed, that enables screen cloning to an
external PAL TV monitor, in color mode. This is accomplished here via
the S-Video connector on the computer.
A color video can be seen here with mplayer, on the telly, if the LCD
is switched off. This picture is played by mplayer, and seen on the
TV set:

(The girl is Kelly Marie, from a video that should be available via
http://www.goodmagazine.com/section/Transparency/Internet_Porn - and
no, it's no porn video ... :)
Funny thing: watching a video on this telly seems to create a much
more pleasing picture on the TV monitor, than the X/KDE desktop as it
is seen on the TV set itself:
KDE desktop, as drawn on the computer, and seen on the TV monitor:

Machine:
Powerbook5,8.
Kernel:
$ git describe --long
v2.6.26-rc5-0-g53c8ba9
The system has the very latest packages - as of around June 10 - for Debian
unstable installed. With only
cinelerra gcc-3.4-base mplayer
held back.
And the upgrade wasn't without glitches: dpkg was bailing out during
upgrade because 1 or 2 packages refused to overwrite files that were
previously installed by different packages, or so. It could be fixed
manually, as it seems ... :)
Cloning was done like along the line of that:
1:
xrandr --output S-video --set load_detection 1
2:
xrandr --output S-video --set tv_standard pal
3:
xrandr --addmode S-video 800x600
4:
xrandr --output S-video --off
5:
xrandr --output S-video --mode 800x600
Seems one can omit step 4.
An S-video to composite adapter was used:
http://www0.info.apple.com/images/kbase/33001/33001_23.gif
which was connected via an adapter to a SCART cable. The latter
connected to a rather cheap 800x600 color PAL TV set.
I'm no sure whether this device is really a 800x600 one. But at least
it works with these values.
xrandr output, while both the LCD and the TV monitor are switched on (Don't
get misled by "S-video disconnected", below: TV monitor *is* connected
*and* shows the KDE desktop):
Thanks a lot to everyone out there who made this possible ... :)
If an Xorg.0.log or an "xrandr -q" is useful, please let me know.
xorg.conf is attached.
Best Regards
Wolfgang
