Hello,
I used CUDA for a while without any problems, but after some problems of version that appeared a few days ago, I have decided to re-install cuda toolkit 7.0.
So I tried to remove all traces of old driver and toolkit versions, and I re-installed it.
The problem is that I cannot run the toolkit samples, nor any other cuda program :
$ ./deviceQuery
./deviceQuery Starting...
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL
However, the driver version is the one installed with the toolkit (352.68) :
$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module 352.68 Tue Dec 1 17:24:11 PST 2015
GCC version: gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04)
$ nvidia-settings -q NvidiaDriverVersion
