What is written here is an awfull translation of this frenchy thread.
If you have configured X11 in order to get :0.1 display on your TV set, and :0.0 display on your standart PC display, then you should try to use VLC like this:
You will get the control windows on your display, but once you have select a video and it start to play, it will play on TV set, in fullscreen mode.( the control windows remains on your main display)Code:vlc --alsadev hw:1,0 --vout x11 --x11-display :0.1 --fullscreen --no-wxwin-embed
--alsadev hw:1,0 : Use it if you have two sound cards, and the second one is linked to TV set
--vout x11 : to invoke X11 mode
--x11-display :0.1 : to get the video windows on :0.1 display
--fullscreen ( ok, it is already translated... )
--no-wxwin-embed : mandatory! : in order to separate control window and display window. VLC will fail without this.
In order to get dual X11 configuration, you can take a look at xorg.conf configuration file here, and i'm sure that a lots of thead already exists on this forum about this subject.
hope it will help
