    Default 2 screens: 1 on and second not in use->issue

    Hi here is one problem with my 9800 pro:
    1/ under ubuntu hardy
    2/ with fglrx driver from the distribution

    I have got 2 screens, first lcd display on vga output, second video projector on dvi output: if I switch off the vdi cable of the video projector all is OK in my LCD display.
    If I switch on the dvi cable on the video projector it is bad !!
    All I want is to have ubuntu in my LCD with my videoprojector switched on with DVI cable while it is inactive with no power.
    I tried many things on xorg.conf, destop=single etc...please help me :-)

    Are you trying to get the same picture from your LCD on your projector?

    Connect your Projector and have it powered on.
    Try this command:
    Code:
    sudo aticonfig --query-monitor
    You should see something like:
    CRT1,DVI1.

    replace "STRING,STRING" with what you see:
    Code:
    sudo aticonfig --enable-monitor=STRING,STRING
    Save what you are doing and reload X
    I forget the shortcut, I think it was CTRL+ALT+SHIFT+Backspace

    Sorry if it doesn't work, Linux is not my main OS. I only use it to test it's progression as a desktop OS.

    thx for your reply, I just want to use only my LCD only I dont care about my projector but it does interfere when connected (low resolution forced, that is what i said "it is bad") with dvi cable even if it is switched off.
    I am going to try what you said but I dont care to clone image in my projector :-)
