Comment 84 for bug 763688

Same problem is happening on my Acer Aspire 2920 subnotebook. Ubuntu 12.04 Precise is able to detect TV output, as you can see on command below:

user@leo-subnote:~$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 800, maximum 8192 x 8192
LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm
   1280x800 60.0*+
   1024x768 60.0
   800x600 60.3 56.2
   640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
   640x480_60.00 59.4
TV1 connected 640x480+1280+0 (normal left inverted right x axis y axis) 0mm x 0mm
   848x480 59.9 +
   640x480 59.9 +
   1024x768 59.9
   800x600 59.9
   640x480_60.00 59.4*

Ignore last TV1 and VGA1 modes. I added manually for testing purposes, to no avail.

I tested S-Video on Windows XP and it's working fine. Didn't tested on older Ubuntu versions, though.

I'll try applying Robert Lowert's patch on my subnotebook somehow.
