CAL version:1.4.792 driver: 10.8 SDK:2.2 CARD: 5970

i install a 5970 card in my server with SDKv2.2, driverv10.7, 

Then i run /root/ati-stream-sdk-v2.2-lnx64/samples/cal/bin/x86_64/FindNumDevices,

Finding out number of devices :-
Device Count = 1.

i found the driver update in 8/25 which version is 10.8.

After updating the driver, FindNumDevices still  isn't normal.

Supported CAL Runtime Version: 1.3.185
Found CAL Runtime Version: 1.4.792
Use -? for help
CAL initialized.
Finding out number of devices :-
Device Count = 0
CAL shutdown successful.

Press enter to exit...

calDeviceGetCount() return error.

What's wrong with my card??

did you run aticonfig --initial --adapter=all?

then try export DISPLAY=:0

default value of DISPLAY is :0.0 which select only first GPU. :0.1 select second etc.
