Good afternoon. I just purchased a pair of ATI 6970M cards for my 'laptop' (clevo x7200). And i'm seeing some very strange behavior.
I run ubuntu 11.04, installed the newest ATI drivers from their site (11.11), configured crossfire, had to use the --acpi-services=off flag just to get GDM to load, and viola, it runs.
oclhashcat+ though, is a different story. It sees both of the GPUs, but runs slower with both than with one:
