我的电脑上有 2 个显示器18.04，一个在内部英特尔 GPU 上运行，第二个屏幕通过 DVI-D 运行NVIDIA GT 710卡，虽然我有最新的415 NVIDIA 驱动程序。在 NVIDIA 连接的显示器上观看视频时，我会看到水平线在视频上不断上下移动，我认为这叫做屏幕撕裂。

我尝试过建议的解决方案，例如设置为中的nvidia-drm.modeset=1线路，但 NVIDIA 显示器会阻止'GRUB_CMDLINE_LINUX_DEFAULT/etc/default/grub启动 Gnome DISPLAY 管理器' 在启动过程中，而另一台显示器登录正常；然后在显示器配置后我再也看不到第二台显示器了。

更新：英特尔显示器也会出现撕裂现象，尽管程度较轻。

答案1

我也有同样的问题。我找到了一些解决方案，也许这有帮助

1. 编辑此文件（或创建它）

sudo nano /etc/modprobe.d/zz-nvidia-modeset.conf

2.并添加此行

选项 nvidia_drm 模式集=1

3. 最后，使用以下命令更新 initramfs

sudo update-initramfs -u

4.然后重新启动。
