我在 Ubuntu 18.04 + Xfce4 桌面上运行 Titan X 显卡，在 Minecraft 打开时拖动窗口时会出现撕裂现象。我有两个显示器，主显示器上的 Minecraft 窗口似乎总是会出现这种情况，但只要我将它们拖到辅助显示器上，所有窗口都会出现这种情况。主显示器上的其他窗口有点不规则。
在安装这两个之前：sudo apt install nvidia-cuda-toolkit gcc-6，按照建议这个帖子，我只经历过鼠标/窗口之间的延迟，但现在我也遇到了撕裂/阴影。仍然很延迟。
我也尝试过在我的 x-server 上强制使用完整的组合管道，并将其保存到我的 X11 文件中，正如建议的那样另一个帖子，但在应用并经历短暂的黑色监视器延迟（我认为是 X11 重置）后没有看到明显的变化。
一旦我关闭 Minecraft，问题就消失了。我不确定 Minecraft 的图形是用什么做的，但我一直在通过 Steam 在 Proton 中模拟游戏，没有任何类似问题。一旦我进入游戏菜单，撕裂就会再次出现。我不需要进入世界，所以我真的不相信这是资源问题。
我不完全确定我使用哪个存储库来安装我的 Nvidia 驱动程序，但它apt list nvidia*给了我一个相当长的 bionic、bionic-updates nvidia 版本列表：

有什么建议么？
答案1
您的系统很有可能允许 Optimus 工作！为此感到高兴吧，因为 Optimus 在 *nix 上 99% 的时间都无法工作。
这样一来，所有 nVidia 芯片组在任何 Linux 发行版上都完全不支持 V-Sync。很有可能它使用 Intel HD，直到 Optimus 发出“哦，等等，我需要做这个”然后它才切换，而且由于 nVidia 上根本没有 V-Sync，整个屏幕都会撕裂。
