Dear all,
I accidentally purged my nvidia driver (375.82), a big mistake…
Then I tried to reinstall it using: sudo apt-get install nvidia-375
After the installation, running ./deviceQuery from cuda samples, it pops out：
$ ./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
The info from running nvidia-smi are:

The I tried to reinstall cuda 8.0 (./cuda_8.0.44_linux.run, downloaded from nvidia official website, ignoring the installation of cuda), the same problem still remains.
Some further information about my ubuntu environment are:

lspci | grep -i nvidia :

Does anyone have any idea how to fix this problem?
Thanks a lot!
Best regards,
