I recently switched from 32 bit Ubuntu 9.04 to 64 bit Ubuntu 9.04.
I am using 180.44 NVIDIA driver that comes with the unrestricted drivers released by Ubuntu
I have installed 2.2 Cuda, since I could not get 2.3 to run with the 180.44 driver, and newer drivers would not work correctly (always would go into low graphics mode or hang X-windows.
Everything compiles successfully in the SDK,
the output of deviceQuery is:
CUDA Device Query (Runtime API) version (CUDART static linking)

if I run simpleStreams I get:
running on: GeForce 8700M GT
cudaSafeCall() Runtime API error in file <simpleStreams.cu>, line 132 : feature is not yet implement
I never got this error running 2.2 Cuda on the 32 bit version. Any suggestions??
