What is the correct "BusID" syntax for device 0x0c:0:0 ?

[chrisr]

Hi,

I have just installed a new 4650 card into my laptop's docking station, and am trying to configure X for dual screen. This is my device section:

Section "Device"
        Identifier  "FireGL-fglrx"
        Driver      "fglrx"
        Option      "OpenGLOverlay" "off"
        Option      "VideoOverlay" "on"
        Option      "UseFastTls" "1"
        Option      "UseInternalAGPGART" "no"
        Option      "MaxGARTSize" "255"
        Option      "BlockSignalsOnLock" "off"
        Option      "TexturedVideoSync" "on"
        BusID       "PCI:1:0:0"
EndSection

Section "Device"
        Identifier  "HD4650-fglrx"
        Driver      "fglrx"
        BusID       "PCI:12:0:0"
        Screen      1
EndSection

However, fglrx is hating this. (It appears to crash the driver.) Omitting the BusID doesn't work either because then I get the following:

(WW) fglrx: No matching Device section for instance (BusID PCI:0@12:0:0) found
(WW) fglrx: No matching Device section for instance (BusID PCI:0@12:0:1) found
(--) Chipset Supported AMD Graphics Processor (0x71D4) found
(WW) fglrx: No matching Device section for instance (BusID PCI:0@12:0:1) found
(**) ChipID override: 0x9498
(**) Chipset Supported AMD Graphics Processor (0x9498) found

Does anyone have any ideas, please? Note that the laptop's primary device is a V5250, and so upgrading the fglrx driver from 9.3 is not an option.

Thanks,
Chris

AFAIK configuration for dual head is done with aticonfig, not with xorg.conf :

aticonfig --initial=dual-head -f

Are you able to disable the internal V5250 ? I'm not sure how the driver will handle multiple GPUs if one is pre-6xx and the other is post-6xx.

Thanks for the reply. I was hoping to keep the V5250 enabled for those times when the laptop is not docked ;-). Regardless, aticonfig seems to imply that the BusID is always the primary device, even for the second Device section. The point seems to be adding "Screen 1" to the second Device section. Although it still doesn't work...

This is as far as it gets.
