[noob here] I am trying to install CUDA 7.5 on my dell laptop which has both Intel and Nvidia GeForce 820M cards. Initially I installed it from .run file and went through so many problems like blackscreen on boot up, etc. After solving those, when I ran deviceQuery, I got error : No CUDA capable device detected.
The error is right as I cant find /dev/nvidia* anywhere.
Here is my inxi -bG output:

I cant find NVIDIA card here;
But when I ran lspci | grep -i nvidia , I got :

Also for running dpkg -l | grep nvidia , I got output:

Currently I have restored my system by installing old nvidia driver 340, and have CUDA 6.5 installed as I was experimenting it with nvidia 340 driver. However,I want CUDA 7.5 to be installed in my machine if possible.
I am fed up from re-installing nvidia driver for getting black screen upon boot up. Please help with this issue, coz I have deadline submission for machine learning very close.
Thanks
