    trouble with my xorg.conf file


    I am kinda new to making my own X installation work so bear with me, I am trying to make gnome work in a arch 7.2 base install. I installed xorg7.0, the ati proprietary drivers and utils, and gnome. I ran xorgconfig to create a xorg.conf file, then ran aticonfig --initial --input=/etc/X11/xorg.conf to customize the xorg.conf file to the fglrx drivers for my card. when I run startx I get the no EE lines and the WW line
    fglrx: No matching Device section for instance (BusID PCI:1:0:1) found
    the following is my xorg.conf file as it is now, only with all the commented lines removed thanks to grep.

    Firstly, these aren't doing anything, delete them:

    Code:
    Section "Device"
    
    Identifier "Standard VGA"
    Driver "vga"
    VendorName "Unknown"
    BoardName "Unknown"
    EndSection
    
    Section "Device"
    
    #VideoRam 131072
    Identifier "** ATI Radeon (generic) [radeon]"
    Driver "fglrx"
    EndSection
    Next, try specifying the Bus ID in the following:

    Code:
    Section "Device"
    Identifier "aticonfig-Device[0]"
    Driver "fglrx"
    BusID "PCI:1:0:0"
    EndSection
    You likely have a dual head card and it often finds PCI:1:0:1 as the second-head pseudo-device living on the AGP card. You may note that
    Code:
    X;
    starts a very boring X server, while
    Code:
    startx
    throws an error.

    you were right that I was able to start it with X;, but only before I made your changes. now I am getting the error
    undefined device "** ATI Radeon (generic) [radeon]"
    whether I start x with "startx" or "X;" I know enough to know that that is coming from the section where I define my screen resolutions and colors but I don't know what it should be referencing so that I can fix it. also I took out all the default stuff thats started in xinitrc but I don't know what I need to add so that it starts gnome for me. once again thanks for the help, and the knowledge.

    A good thing to do might be to change all of the identifiers to simple stuff like "AtiCard", "Screen0", etc., so that when you reference these things throughout the conf its clearer whats going on. try simplifying this conf file to just one screen, one display and one device each labeled reasonable identifiers. then replace the references to each with the only possible identifier which will then have to be correct.

    I understand what you are saying. I guess the question really is; does that section, the one defining resolution and color settings, get described as a monitor, a screen, or a device? I know its not device, I understand that that is my video card. what I don't understand is what distinction does Xorg make between a screen and a monitor. since I don't know the difference I don't know what section falls into which category. sorry if I sound kinda noobish but I have never set up X manually before, always gone console only or used a distro that configured it for me.
