我刚刚在我的联想 ThinkPad X1 Extreme 上安装了 Ubuntu 18.04，除了我的 Nvidia 驱动程序之外，一切似乎都正常（最糟糕的是我无法连接到扩展显示器）。
我的规格
Machine Type : Notebook
Processor : Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz
Operating System : Ubuntu 18.04.1 LTS
GP107M [GeForce GTX 1050 Ti Mobile]
Kernel Version -
4.15.0-46-generic
BIOS settings -
*Discrete graphics
我尝试过的方法
* 使用 Ubuntu 自带的默认驱动程序 * 使用 安装驱动程序apt-get install nvidia-driver-418
* 使用 Nvidia 安装程序 安装驱动程序（不运行 x11，使用sh ./NVIDIA-Linux-x86_64-418.56.run）
* 运行nvidia-settings
* 使用 lightDM 而不是 GNOM
* 清除所有 nvidia* 并从发行版安装nvidia-driver-390（而不是推荐的那个）
* 以及我在网上找到的更多建议
我现在的状态是什么
驱动程序仍然无法工作 -
#> nvidia-smi
NVIDIA-SMI couldn't find libnvidia-ml.so library in your system. Please make sure that the NVIDIA Display Driver is properly installed and present in your system.
Please also try adding directory that contains libnvidia-ml.so to your system PATH.
（尝试运行但LD_PRELOAD=/usr/lib/i386-linux-gnu/libnvidia-ml.so nvidia-smi没有成功。）
该nvidia-settings命令仍然打开空白屏幕，输出是 -
ERROR: Unable to load info from any available system

** Message: 12:17:57.419: PRIME: No offloading required. Abort
** Message: 12:17:57.419: PRIME: is it supported? no
当我跑步时ubuntu-drivers devices我仍然会 -

尽管它已经安装好了。
该hardinfo命令显示“图形”是“未知”。

我真的不知道该怎么做，而且似乎司机已安装但实际上并未加载。
我找不到使用modprobe或其他任何方式加载它的方法。
任何帮助都会有帮助！：祈祷：
答案1
明白了。不幸的是，联想安全启动似乎阻止了驱动程序的启动。在 BIOS 上禁用它并重新启动进入 Ubuntu 后，我看到了 Nvidia 徽标，并且我可以使用nvidia-smi和nvidia-settings。
答案2
这就是我在 Thinkpad T580 上安装 Nvidia 显卡驱动程序的方法。
从应用程序菜单转到系统设置->细节并检查是否正在使用 Nvidia 显卡。打开软件和更新，然后点击额外的司机选项卡。选择选项使用来自 nvidea-driver-390 的 NVIDEA 驱动程序元包并点击应用更改按钮。
此外，禁用 UEFI 安全启动。重启电脑。在应用程序菜单中，打开 NVIDEA X 服务器设置，在 PRIME 配置文件选项卡中选择 NVIDEA。
