我已nvidia-driver-415通过软件和更新为我的双 GTX 970 安装了。重启后，我的屏幕分辨率现在卡在 1024x 768 像素。我有两个显示器，现在只有一个可以工作。
我还注意到我的电脑现在发出的噪音大了很多。重叠窗口也出现了一些奇怪的故障。
以下是我的系统规格：
非常感谢您的帮助！我厌倦了重新安装 Ubuntu 只是为了解决这个愚蠢的问题。
顺便说一句：即使将驱动程序设置回 X.org S 服务器 - 来自 xserver-xorg-vidoe-nouveau（开源）的 Nouveau 显示驱动程序，问题仍然存在。

答案1
就我自己的经历来说，
我在用nvidia-驱动程序-390和
我在安装了 Ubuntu 18.04 LTS 的 Asus X550VX（GeForce GTX 950M）笔记本电脑上没有任何分辨率问题。
您可以尝试降级到nvidia-驱动程序-390驱动程序版本。
答案2
快速更新
对我来说，更新到 Ubuntu 19 似乎可以解决问题。
