关于 Nvidia 驱动程序的困惑

我是 Linux 新手,使用 ubuntu 14.04 LTS,我的问题是,我对 nvidia 驱动程序设置感到困惑,使用nvidia-smi,它给出

并且在 Nvidia X 服务器设置的 PRIME 配置文件中,它显示我使用的是 NVIDIA 卡,而不是 Intel 卡,但在软件和更新中,使用附加驱动程序时,它显示我使用的是 nouveau 驱动程序,但未选择 Nvidia 375 版本的驱动程序。(抱歉,我没有足够的声誉来发布图片)但是dpkg -l|grep nvidia,我只安装了 367 版本:

cc@cc-Lenovo-Rescuer-14ISK:~/Downloads$ dpkg -l|grep nvidia
ii  nvidia-367                                            367.57-0ubuntu0.14.04.1                             amd64        NVIDIA binary driver - version 367.57
ii  nvidia-opencl-icd-367                                 367.57-0ubuntu0.14.04.1                             amd64        NVIDIA OpenCL ICD

ii  nvidia-settings                                       367.48-0ubuntu1                                     amd64        Tool for configuring the NVIDIA graphics driver

所以我的困惑是:我真正使用的是什么?这个版本 375 是否已安装在我的系统中,我可以切换到它吗?附加驱动程序选项到底有什么用?提前致谢!

编辑lspci -k | grep -EA3 'VGA|3D'给出:
