最近我注意到，在窗口周围以及所有应用程序的右键菜单上，都有这些奇怪的彩色条纹。它们在我重新启动 Ubuntu 或 Unity 后消失，但不久后又出现。
我的笔记本电脑使用的是 NVIDIA GeForce 960M，对于那些知道的人来说，我几周前才开始 CUDA 编程。
这些是与 nvidia 相关的已安装的软件包：
quan@quantran:~$ sudo apt list --installed | grep nvidia

罪魁祸首确实是 NVidia 驱动程序的新版本。恢复到 375 不起作用，因为在我看来它也已更新（次要版本）和/或其依赖项是多个版本的混合。无论如何：
- 删除 PPA。在我的电脑上，我删除了
/etc/apt/sources.list.d/graphics-drivers-ubuntu-ppa-xenial.list指向存储库的文件deb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu xenial main - 删除所有已安装的 NVidia 软件包，例如
nvidia-*。在我的电脑上，我使用以下命令删除了几个软件包apt remove nvidia-361 nvidia-375 nvidia-378 - 使用以下命令更新软件包列表
apt update - 使用以下方式安装最新官方版本（即 367）
apt install nvidia-367
顺便说一句，我总是惊讶于更新如何定期破坏 Ubuntu......
