I have two ati cards - radeon 2200 HD and radeon 5870 HD
I want to configure both these cards on OpenSUSE 11.2 x64 box
with 2400HD for display
and the 5870 for the OpenCL compute only...
tried out the straightforward way of plugging in the two cards and installing the drivers - didn't work
the seconds card - 5870 hd is not recognized..
am i missing something ?
Did you use aticonfig to set up the graphics cards?
Type 'aticonfig --lsa' to list all installed graphics cards. If all cards are listed, type 'aticonfig --adapter=all --initial -f'. This will make sure that drivers for all cards will be loaded the next time you start X.
I had some problems using Gnome as a normal user (not root) after this, however (maybe because I was trying to use multiple GPUs but only one of them has a monitor connected). I solved this problem by using xterm instead of Gnome.
hey thanks dominik_g
yeah aticonfig --lsa lists both
But, when i run the stream SDK samples if fails with
and i am not able to see both the cards in amdccle (catalyst conrol center)
I guess the SDK fails because only the driver for the 2400 HD is loaded and this card is not supported by the SDK, right?
I'm surprised that amdcccle only shows one of the cards. Have you tried 'aticonfig --adapter=all --initial -f'?
If it fails you can always undo it by typing 'aticonfig --initial -f' (You may have to boot in single-user mode)
yeah 2400 HD is not supported by the SDK
so the CLInfo show only the CPU
i did aticonfig --adapter=all --initial -f, even with that 5870 doesn;t show up in amdcccle
but with aticonfig --lsa
both cards are listed with 2400 HD marked as the default...
is that a problem in anyway ?

That sounds fine. It recognizes both cards and te 2400 HD is used for output.
Can you print the contents of your xorg.conf ('cat /etc/X11/xorg.conf'). How many screens are listed in the ServerLayout section?
I should be having only one, right ?
i have a single display
here is the xorg.conf
Section "ServerLayout" Identifier "Layout0" Screen 0 "aticonfig-Screen-0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "Module" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "aticonfig-Monitor-0" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Device" Identifier "aticonfig-Device-0" Driver "fglrx" BusID "PCI:15:0:0" EndSection Section "Screen" Identifier "aticonfig-Screen-0" Device "aticonfig-Device-0" Monitor "aticonfig-Monitor-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection
Well, you only have a single display, but I think you have to pretend to have multiple displays if you want to use multiple GPUs. Normally 'aticonfig --adapter=all --initial -f' creates a new xorg.conf with one screen for each GPU...
What is the output of 'aticonfig --adapter=all --initial -f'?
so do i have to configure the GPUs with multiple head displays ?
below is the output of "aticonfig --adapters=all --initial -f"

Did you try running the CAL samples? 'FindNumDevices' sample will tell you if both the devices are being detected properly.
Also, do you have a monitor attached to the second card? If not, could you try that way too?
