this option can be set in /etc/X11/xorg.conf. Just add Option "Interactive" "0" to the device section of your GPU. Here is what my device section looks like:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 460"
    Option         "Interactive" "0"
EndSection

I run the same version of CUDA in ubuntu but I'm using OpenCL. Profiling with one of these instructions causes high CPU usage and never finishes (I have to kill the process) - even when interactive mode is disabled. Anyways, you can give it a try.

Also make sure to verify the compute capability of your GPU and check if the requested count is supported : Visual Profiler User Guide. Although it seems that this is not the cause of you problem since it's working in OS X.
