窗户周围奇怪的彩色条纹 – Ubuntu 16.04
所以最近我注意到，在窗口和所有应用程序的右键菜单中，都有这些奇怪的彩色条纹。 它们在重新启动Ubuntu或Unity后消失，但之后不久又出现了。
终端窗口周围的彩色条纹
我的笔记本电脑使用的是NVIDIA GeForce 960M，对于那些知道的人，我几周前刚刚开始使用CUDA编程。
这些是与nvidia相关的已安装软件包：

提前谢谢大家！
罪魁祸首确实是NVidia驱动程序的新版本。 恢复到375不起作用，因为恕我直言它也已更新（次要版本）和/或其依赖项是几个版本的混合。 无论如何：
- 删除PPA。 在我的计算机上，我删除了文件
/etc/apt/sources.list.d/graphics-drivers-ubuntu-ppa-xenial.list指向存储库deb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu xenial main - 删除所有已安装的NVidia软件包，即
nvidia-*。 在我的计算机上，我删除了几个包，用apt remove nvidia-361 nvidia-375 nvidia-378 - 使用
apt update包列表 - 使用
apt install nvidia-367安装最新的官方版本（即367）
作为旁注，我总是惊讶于更新经常打破Ubuntu ……
