很抱歉让你陷入这种困境，但我很确定我不是唯一一个遇到这个问题的人：
我有一台相对较新的笔记本电脑，配备 Ge-force 1050TI。由于我需要能够运行需要 cuDNN 库的初步模型，因此我无法使用 ubuntu 驱动程序，而是在 Ubuntu 19.04 系统上安装了 nvidia 430 驱动程序。驱动程序运行良好，包括 cuDNN，但无论我尝试什么，我只能让内部或外部显示器工作：使用 GDM3 时，只有内部显示器可以工作。使用 Lightdm 和 xorg 时，只有外部显示器可以工作。
请有人帮我省去花更多时间处理这个问题的麻烦！以下是一些调试输出。如果您需要更多信息，请告诉我 - 我会尽我所能。

对于有同样问题的人：
我必须重新安装并安装 ubuntu nvidia 驱动程序。在安装过程中选中该复选框或：sudo ubuntu-drivers autoinstall
当前适用于我的自动安装版本是 418.56 ， 430+ 目前处于测试阶段。
为了使 tensorflow > 1.3 工作，仅通过 Anacona 安装 CuDNN（使用 conda install tensorflow-gpu 而不是 pip install tensorflow-gpu）。
现在，除了 s2idle 或任何挂起/待机/休眠之外，显卡周围的一切都正常工作。似乎也与 NVIDIA 有关，但也可能是 HP Spectre x360 特有的。当我找到解决方案时，我会发布。
