我有 Manjaro/XFCE/LightDM 和 GeForce GT 710，我遵循本指南摆脱撕裂。我将这三行添加到我的 X 配置中。我登录欢迎程序后，屏幕仅显示背景图像和鼠标光标。按 Ctrl+Alt+F2 和 Ctrl+Alt+F7 后，我可以看到桌面和自动启动的应用程序。如果没有这三行，桌面和应用程序将立即可见。
是的，我用谷歌搜索过。

我可能缺少您需要的一个文件，所以请让我知道您需要什么（以及不需要什么，因为我这里限制为 30k 文本...）。
答案1
更新：我找到了另一个可能的解决方案在 Nvidia 论坛上：删除文件~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml。
我有同样的问题，并将其缩小到“组合管道”设置。启用后，XFCE 桌面不会变得可见，但 LightDM 背景仍保留在屏幕上。在 TTY 之间切换会强制屏幕更新，从而解决问题，但这很麻烦。
如果您从 X 配置中删除“元模式”设置，问题应该会解决，但您将再次遇到屏幕撕裂的情况。
对我有用的是在会话启动时运行以下命令（您可以将其添加到 XFCE 的会话和启动设置中）以强制屏幕在启用组合管道的情况下更新：
nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceCompositionPipeline = On }"
ForceFullCompositionPipeline = On请注意，您可能也想添加。
这显然是一种解决方法，我不知道根本原因是什么或如何解决它。其他显示管理器似乎在启用该设置的情况下工作正常。
