when i plug in an s-video line which is connected to a TV it does not get 
recognized by xrandr and i can't switch with Fn4 between LVDS and VGA-0, here 
is what i get from xrandr:
laptop:~# xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2304 x 1024
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 
0mm
   1024x768       60.0     60.0*
   800x600        60.3
   640x480        59.9
S-video disconnected (normal left inverted right x axis y axis)

only after a reboot i can use Fn4 to switch the s-video output to watch on the 
TV but still it's not recognized with xrandr.

also, i get these line in xorg log file:
information	RADEON(0): Output S-video has no monitor section
information	RADEON(0): Output S-video disconnected
