    So back to sudo gedit /etc/x11/xorg.conf ..... empty. hmm

    Pasted in the contents again and it wouldn't let me save it saying something about not existing.

    Double checked the path... nope got it right. So what's going on??

    I can look in /etc/x11/xorg.conf with nautilus and see the contents but if I sudo gedit /etc/x11/xorg.conf there's nothing in there and furthermore I cannot edit it.

    arrgghh

    any thoughts greatly appreciated

    The file should be at: /etc/X11/xorg.conf (capital X). If you are going to use a GUI text editor such as gedit then the incantation from the terminal should be
    Code:
    gksudo gedit/etc/X11/xorg.conf
    If you wish to use a terminal based editor such as nano or vim you can use
    Code:
    sudo nano /etc/X11/xorg.conf
    The command sudo should only be used for terminal based apps. The command gksudo is used for GUI based apps (even if you are launching them from the terminal). FYI -- to detach the GUI editor from the terminal you can use an & at the end of the incantation. This will allow you to close or reuse the terminal without killing gedit. It looks like this
    Code:
    gksudo /etc/X11/xorg.conf &
    -BAB1

    For ubuntu 11.10 the only thin which worked was

    1) Install dummy monitor by
    Code:
    sudo apt-get install xserver-xorg-video-dummy
    2) Backup xorg.conf by
    Code:
    sudo  mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
    3) Then create a new xorg.conf
    Code:
    sudo gedit /etc/X11/xorg.conf
    with:

    Code:
    Section "Device"
        Identifier  "Configured Video Device"
        Driver      "dummy"
    EndSection
    
    Section "Monitor"
        Identifier  "Configured Monitor"
        HorizSync 31.5-48.5
        VertRefresh 50-70
    EndSection
    
    Section "Screen"
        Identifier  "Default Screen"
        Monitor     "Configured Monitor"
        Device      "Configured Video Device"
        DefaultDepth 24
        SubSection "Display"
        Depth 24
        Modes "1024x800"
        EndSubSection
    EndSection

    here's a simple hardware solution that causes computer to recognize a fake monitor, all you need is three, 75 ohm resistors.
    here is the link

    Re: 10.04 won't boot without monitor / keyboard (headless)

    Sorry to dig up such an ancient topic from grave, but I need help. Trouble following instructions per /etc/default/grub. Such a file doesn't exist on my system, ubuntu 10.04. Boots otherwise just fine. What would the alternative to this file be?

    I think it's under "/boot/grub".

    The answer is actually a combination of two separate solutions, each of which did not work separately. I have 10.04 now working headless on two different servers (different MB, Video...) and both are working great.

    Step 1. Create a xorg.conf in (...)
    Step 2. Disable KMS for your video card (...)
    Step 3. Reboot...Putty In...startx...GTG!
    OH MAN I COULD KISS YOU RIGHT NOW!!!!!!!!!!!

    Spend DAYS looking for this solution.. HEADLESS 10.04 LTS 64bits but nothing worked.. until you came and saved the day!!

    If I weren't buried in depth and without a job, I would surely donate! Thank you, neoliberals!

    Again, thank you so much!!

    *NOTE* I had previously also installed the x11 dummy driver
    (sudo apt-get install xserver-xorg-video-dummy) in case someone trying this.
