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
| NVIDIA-SMI 367.57 Driver Version: 367.57 |
|-------------------------------+----------------------+----------------------+

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-prime 0.6.2.1 amd64 Tools to enable NVIDIA's Prime
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!
