Cuda install thinkpad w530

my laptop has a quadro k1000m gpu and intel 3rd gen graphics
Ubuntu 14.04 LTS
I have cuda 6.5 installed (or so I think)
I have multiple nvidia drivers installed for the k1000m (352.63 , 340.96, 304.131) but I’m currently using version 352.68
after running through many configurations with deviceQuery saying many different things (all errors) I’ve settled on a configuration that I believe is mostly correct. Although the deviceQuery fails with error: no cuda capable device detected.

I’m not totally familiar with what info I need to post (like the output of nvcc -V?) so let me know if I missed some key information.

*****nvcc -V:

You think you have CUDA 6.5 installed but the nvcc -v shows CUDA 5.5. You list 4 different driver versions. It looks like a mess to me.

Almost certainly your driver install is broken.

I can’t tell by what methods you installed either CUDA or the drivers (runfile or package manager).

My suggestion would be to start over with a clean load of the OS, or else follow the instructions in the linux getting started guide and perform all cleaning/removal steps indicated for both package manager and runfile installers, for both CUDA toolkit and driver.

Then pick a single CUDA toolkit that you want to use, and follow the instructions to install it.
