no CUDA-capable device is available

Hi,

I succesfully installed cuda toolkit and compiled cuda SDK but when I run “~/NVIDIA_GPU_Computing_SDK/C/bin/linux/release/scan”, I get this message :

cudaSafeCall() Runtime API error in file <scan.cu>, line 100 : no CUDA-capable device is available.

I’m on ubuntu 9.10 with nVidia 190.42 driver from VDPAU Team PPA (https://launchpad.net/~nvidia-vdpau/+archive/ppa?field.series_filter=karmic)

Any idea?

Thanks!

Please be sure that you have writes to interact with graphics card. give rights to your user to read and write to Graphics Card.

Good Luck :teehee:

That is ls -l /dev/nvidia*

should discover at least two devices (nvidia0 and nvidiactl)

and your user id should have (rw) write access to them

even though they may be owned by root
