Twinview a LCD and HD projector

[addisor]

Where should I start? would like to have my LCD monitor screen (via vga) and my Yamaha projector (via dvi) for movies. I have a basic understanding of twinview, but would like to tweak output so that film only plays on projector and ubuntu stays on LCD.

Hi

I couldn´t get a similar setup with twinview, so I decided to go with 2 xservers.
works pretty well.
Standard dekstop on LCD, Movies on my 1080p RPTV.

Here is the relevant part from my xorg conf

I´m starting just mplayer or xine with a smal script, so the movie starts playing on the 2nd Display.

DISPLAY=:0.1
mplayer -lavdopts threads=2 -vo xv -monitoraspect 16:9 -fs -ao alsa -ac hwac3 -cache 8096 "$@"

I´m using a nvidia 7600GS, LCD on DVI, HDTV on DVI-HDMI cable, Driver 9746.

hope this helps
