I recently installed the Cuda Toolkit 3.2.16 for 64bit Ubuntu 10.04 on my machine that is running 10.10 with a GeForce GTX 260 card. I was able to install and compile SDK examples fine. On running deviceQuery it passes:
./deviceQuery Starting…
CUDA Device Query (Runtime API) version (CUDART static linking)

but running bandwithTest fails with:
./bandwidthTest Starting…
Running on…
Device 0: GeForce GTX 260
Quick Mode
bandwidthTest.cu(598) : cudaSafeCall() Runtime API error : all CUDA-capable devices are busy or unavailable.
Running matrixMul gives the same busy/unavailable error. I then ran matrixMulDrv to check the error code and got an unknown:
./matrixMulDrv
[ matrixMulDrv (Driver API) ]
Using CUDA Device [0]: GeForce GTX 260
GPU Device has SM 1.3 compute capability
Total amount of global memory: 1878327296 bytes

cuSafeCallNoSync() Driver API error = 0999 from file <matrixMulDrv.cpp>, line 89.
I tried drivers 260.19.36 and 260.19.26.
Does anybody know what problem I might be having? Is it just not possible to run the toolkit designed for 10.04 on 10.10?
Thanks for any help!
