Ubuntu 从 17.10 升级到 18.04 后出现 nvidia 屏幕撕裂

我尝试了多种修复方法来解决此问题。

沒有起到作用的事情；

  1. 在 xorg.conf 中设置三重缓冲
  2. 在 xorg.conf 中设置 ForceFullCompositionPipeline
  3. 确保在 Nvidia 的 OpenGL 设置选项卡中启用 Vblank。
  4. 编辑 zz-nvidia-modeset.conf 中的 Nvidia 模式集并更新 initramfs

有任何想法吗？

当前的xorg.conf

回答我自己的问题。我意识到 GPU 根本没有被利用，而是回到 CPU 进行处理（不知道为什么会这样）。

我通过清除 nvidia 然后重新安装来修复它；

sudo apt-get remove --purge nvidia-*

sudo apt-get install nvidia-390

重新启动后，屏幕撕裂现象消失，游戏再次正常运行。
