    Unhappy Triple Monitors Help


    First time configuring multiple monitor configuration. Not getting much of anywhere. Any help would be appreciated.

    I have 3 monitors.
    Samsung Syncmaster 913v
    Acer AL2223W Widescreen
    Samsung Syncmaster 920n

    Getting the following errors:
    (WW) RADEON: No matching Device section for instance (BusID PCI:1:11:0) found
    (WW) I810: No matching Device section for instance (BusID PCI:0:2:0) found
    (EE) Screen 0 deleted because of no matching config section.
    (II) UnloadModule: "i810"
    (EE) Device(s) detected, but none match those in the config file.

    Fatal server error:
    no screens found


    Video Cards:

    Onboard i810 chipset is hooked up to the AL2223W
    Radeon 9200 Video card (gets detected at 7000 though, see below)

    Relevant lspci results:

    00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)
    01:0b.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]

    Screen in device config doesn't mean screen... Bad naming!

    The "Screen" parameter in the device section has NOTHING to do with the defined screens. It's the identifier for each head on a multi head card. It's POORLY NAMED and NEEDS FIXED xorg devs!!!!

    Here's what it should look like.
