nUbuntu Dual Monitor Help!


Hardware:
Compaq Presario Desktop
AMD Sempron Processor
ATI Radeon 8500 LE/R200 QL
HP L1940T Monitor
Norwood Micro Generic Monitor
nUbuntu 8.12 Beta

I am trying to run dual monitors on nUbuntu with kde desktop installed I would like them to run as separate desktops and I can drag windows from one to the other. I have 2 ports on my ATI graphics card. one is VGA and one is DVI. I have an adapter on the DVI port to make it VGA. I have both screens plugged into the ports and right now they are cloning each other. The Generic configuration for my xorg.conf file is this:
Code:
Section "Device"
   Identifier       "Configured Video Device"
EndSection

Section "Monitor 
   Identifier       "Configured Monitor"
EndSection

Section "Screen"
   Identifier       "Default Screen"
   Monitor          "Configured Monitor"
   Device           "Configured Video Device"
EndSection
I know...Very strange for a xorg.conf. Not even any file section or sections for my mouse and keyboard (which both work fine by the way), and no..there is no other files in the X11 folder that even resemble xorg.conf (such as XF86conf or xorg.conf-4). I have tried to manually configure it but with only the error that when I start up the computer and type startx. it shows errors such as "no screens found" and "fatal server error". Here is my manual configuration:
Code:
Section "ServerLayout"
    Identifier  "XoRg.cOnF"
    Screen      "screen0"
    Screen      "screen1" RightOf "screen0"
    InputDevice "Generic Keyboard"
    InputDevice "Configured Mouse"

    # I don't know if I need this...
    Option "xinerama" "on"
    Option "clone" "off"
EndSection

Section "Device"
    Identifier  "radeon0"
    Driver      "ati"
    BusID       "PCI:1:0:0" #I think this is the port..any way to check?
    Screen 0
EndSection

Section "Device"

    BusID       "PCI:1:0:0"

New xorg doesn't even need an xorg.conf, so most of the older xorg settings are being removed. Mine looks like this:

if the ati drivers have an xorg.conf configure program I'd recomend using it. You can also delete the xorg.conf as of a certain xorg release.... though I don't remember what release it was...

nnicnac,

Please do not post the exact same issue in more than one place. Other members would rather find your thread once and keep the discussion in a single location. Your other thread HERE will be closed.

For further info about creating threads and general LQ use, please read This

Thank you,
Sasha

AHAHA I figured out your major problem already!!! Oh man, so my roomate has a 9200 and if he didn't have that I don't know squat about ATI. Every chip r300 and below has been discontinued, that means your r200, the r250 (9xxx) and whatever the r300 is. You have to use the opensource drivers for ATI to get anything decent working. So go look towards the mesa drivers for ati, and good luck you will need it. Pretty much ATI dropped support for the old cards, so you can't install the propriatiary drivers.

I apologize, I was going to move the thread to this section to hope for more help, but I did not know how(very new). I thought I would just re-post here and delete my other post but I got side tracked with the problem and forgot.

It's a headache getting the older cards to work that's why I said good luck, AMD/ATi kind of made things muck. Just google ATI Open Source Driver and try different solutions. Some of the xorg flags still work and will help the card, though finding out what they are... It's a mess =( trial and error. I did get a nice FPS in glxgears once, don't remember how, but full 3D and other support is there.
