为 Nvidia Geforce 820M 安装 Ubuntu 16.04 驱动程序

为 Nvidia Geforce 820M 安装 Ubuntu 16.04 驱动程序

我有一台联想 Z50-70 笔记本电脑,它有英特尔集成显卡和 Nvidia Geforce 820M;但是,自从我安装了 Ubuntu 16.04 以来,它一直没有使用显卡。我尝试卸载所有与 Nvidia 相关的东西并重新安装nvidia-375,然后声明它依赖于libc6-i386,然后返回

The following packages have unmet dependencies.
 libc6-i386 : Depends: libc6 (= 2.23-0ubuntu3) but 2.23-0ubuntu5 is to be installed
E: Unable to correct problems, you have held broken packages.

当我尝试安装时libc6,我得到了libc6 is already the newest version (2.23-0ubuntu5).

我该如何安装这些,或者是否有其他方法可以使我的显卡工作?

就其他命令而言:

lspci -vnn | grep 3D -A 12返回:

答案1

  1. 如果您grep VGA使用 ,则会看到 Nvidia 适配器grep 3D

  2. nvidia-340不适合此适配器。安装nvidia-375

您只连接了mainuniverserepos。转到系统设置 -> 软件和更新并启用所有其他 repos,尤其是restrictedxenial-updates也没有连接。您也需要启用它。

您可能需要在安装驱动程序之前更新系统。
