    Hello,
    for some reason the FN + F7 key does not work anymore when i press it, it used to work just fine but after yesterday or day before update for ubuntu it stopped working

    any idea what might be the problem or how to manually press it? because my DisplayPort is not enabled by default even when mirroring the screens it doesn't work, only the VGA port when mirroring screens works

    Please advise.

    Thank you

    Fn+F7 is the hotkey which switches display input/output. Like laptop only, laptop/external display, external display only.

    Screen Resolution tool in Preferences, maybe nvidia-settings if you have a nvidia card

    i have ATI card, but screen resolution does not detect the card as another monitor i need to clone my screen to work on VGA port but the DisplayPort it doesn't detect it...

    any other workaround?

    Only other way I can think of is to manually edit /etc/X11/xorg.conf
    And no I don't know what you should append in there.

    Try google or perhaps some Linux guru will give you the answer.

    Bashar: I have an Intel GPU in my T61, but it also uses the Fn+F7 display hotkey. The behavior of the key is controlled by the file:
    Code: 
    /etc/acpi/ibm-videobtn.sh
    Edit that file, and you can configure what the key actually does. I don't know how the ATI driver deals with it, but xrandr is the new X modification applications, changes how multiple screens and such are treated. I personally have Xdialog installed so I can pop up a dialog when I hit Fn+F7 and select how I want my screen changed. I've attached my ibm-videobtn.sh script if you want to use it or take a look at it. It should work with very little modification for you.
