Help! I'm running Xubuntu 10.10 (Xfce 4.6.2) on a Thinkpad R51 with onboard Intel graphics. I'm basically trying to set this up as a HTPC with XBMC to using in the living room. I've finally got everything working, except I still can't get the S-video output to work.

I've searched all over and found a few tips/workarounds, but nothing has helped.

If I startup with the S-video cable connected, the TV flashes white once, briefly, at the POST screen, but nothing else.

Here is the relevant part of lspci:


00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)
00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)My xorg.conf file looks like this (most of it was copied to cope with the error explained here: https://wiki.ubuntu.com/X/Bugs/Mavericki8xxStatus). I have to use the intel driver, otherwise Hardware Acceleration/OpenGL get disabled and no-go on XBMC.


Section "Device"
Identifier "Configured Video Device"
Driver "intel"
Option "monitor-VGA" "VGA"
Option "monitor-TV" "TV"
Option "monitor-LVCD" "LVCD"
Option "monitor-Svideo" "S-Video
EndSection

Section "Monitor"
Identifier "Configured Monitor"

Section "Monitor"

Option "Ignore" "true"

Section "Monitor"

EndSection

Section "Monitor"

EndSection
When i view xrandr, it shows the laptop display and the VGA port, but not TV out or S-video I've verified the VGA port works with this config just by plugging it in (I'm viewing a cloned desktop on a CRT monitor right now).

720x400 85.0
640x400 85.1
640x350 85.1 I don't need extended desktop, or anything like that. I just want to view the screen on a TV so I can leave the laptop on a shelf closed.

Does anyone have any tips or ideas on what I can do to get S-video output working on my machine? If more info is needed, I'd be happy to provide to get my problem resolved.

Thanks.

i810 drivers works for s-video. somehow i810 drivers dont work well with recent kernels. dont know what modifications they need.
how about using vga to s-video converter and do vga out.
p.s. vga to s-video cable may not work in some cases you will
need converter only.

You could check if it is intel/kernel related.
Disable the xorg.conf (or choose "vesa" instead of "intel" ),
then check
xrandr -q again....
