dual head 2nd view setup with free radeon drivers on 64bit arch

Hi,

I have recently installed 64bit Arch on my desktop pc and having trouble getting the dual head setup to work.

Since the proprietary ati drivers seem not to be supported for my card (radeon X850) anymore, I tried the free radeon drivers. Singel head setup works fine, but i am allways getting a clone view. Here is my xorg.conf:

Section "Files"
    ModulePath   "/usr/lib/xorg/modules"
    FontPath     "/usr/share/fonts/misc"
    FontPath     "/usr/share/fonts/100dpi:unscaled"
    FontPath     "/usr/share/fonts/75dpi:unscaled"
    FontPath     "/usr/share/fonts/TTF"
    FontPath     "/usr/share/fonts/Type1"
EndSection

Section "Module"
    Load  "glx"
    Load  "dri"
    Load  "extmod"
    Load  "dbe"
    Load  "dri2"
EndSection

EndSection

Section "Monitor"
    Identifier   "Monitor1"
    HorizSync    30.0 - 98.0

           ViewPort    0 0
    EndSubsection

EndSection

    InputDevice    "Mouse0" "CorePointer"
    InputDevice    "Keyboard0" "CoreKeyboard"
EndSection


Section "DRI"
   Mode 0666
EndSection

When I unconmmend the Screen number identifier in the device section, the X-server freezes.

I hope you can help me with this.

Re: dual head 2nd view setup with free radeon drivers on 64bit arch

My video is the Radeon 4200 that is integrated on the AMi 785G chip set. I think that is RS780. Here's my xorg.conf that does dual head OK:

Section "Module"
    load "glx"
    load "dri"
    load "drm"
EndSection

Section "Device"
        Identifier  "HD4200"
        Driver      "radeon"
        BusID       "PCI:1:5:0"
    Option      "AccelMethod" "EXA"
    Option      "DynamicPM" "on"
    Option      "ClockGating" "on"
    Option      "DMAforXv" "on"
        Option      "Monitor-VGA-0"  "Samsung"
        Option      "Monitor-DVI-0"  "Dell"
EndSection

Section "Screen"
        Identifier   "HD4200"
        Device       "HD4200"
        DefaultDepth     24
    Subsection "Display"
                Virtual 3200 1200
        EndSubsection
EndSection

Section "Monitor"
        Identifier   "Dell"
        Option       "DPMS" "true"
EndSection

Section "Monitor"
        Identifier   "Samsung"
        Option       "DPMS" "true"
    Option       "RightOf" "Dell"
EndSection

Section "DRI"
 Group        "video"
 Mode         0666
EndSection

Thank you for the answer, but this creates one virtual screen over both monitors.
I need a setup with two separate screens.
