CUDA Toolkit6.5를 설치치중인데.. 설치 메뉴얼에 다음과 같은 문구가 있는데요,

6.3.1. Verify the Driver Version
If you installed the driver, verify that the correct version of it is installed.
This can be done through your System Properties (or equivalent) or by executing the
command
$ cat /proc/driver/nvidia/version
Note that this command will not work on an iGPU/dGPU system.

여기서 iGPU/dGPU라는 말이 있는데, 이게 뭔지 잘 못찾겠어요 ㅠ
