Unfortunately, load detection for tv-out is inherently unreliable on a lot of boards (You can end up with false positives and false negatives). The best option is to force the tv-out connection on or off in your console or xorg config.

Fair enough, however that's what I tried but it doesn't seem to work either. I have this definition in xorg.conf:

Section "Monitor" Identifier "S-Video Monitor" Option "Enabled" "false" EndSection

It's: Option "Enable" "False" However, some older xservers (maybe recent ones too), do not deal with enable false, you need to use: Option "Disable" "True"
