Audio-Visual Installation Question

If you can get your xorg.conf configured to a 'dual-head' setup where the 2nd
screen is on the external vga connector of your laptop - going to the
projector, then you should be able to achieve this.

The video player could sit on screen2 whilst audacity would sit on screen1 as
well as the control to the video playback (if separable).

Depending on the driver, this should be possible.

google the make and model of your video card and keywords like :  dual-head
ubuntu etc

You will have to dig around a bit, as I looked just now and didn't find any
success stories for that model.

You could try the ubuntu 'screens and graphics' menu option to see if it can see
the second display already, but I doubt it based on recent experiences.

Eventually, you will just need to configure /etc/X11/xorg.conf (make a backup
copy of it before you do anything to xorg.working so you can restore your
working display from the command line with 'sudo cp /etc/X11/xorg.working
/etc/X11/xorg.conf' should you loose crash your xserver) to include 2 screen
sections plus a layout section that looks something like :

Section "ServerLayout"
        Identifier      "DualHead"
        Screen      0  "Screen0" 0 0
        Screen      1  "Screen1" LeftOf "Screen0"
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"

The example is pretty rough, but might point you in the right direction.
