我目前在带有 GTX 1080 的 arch linux 上使用带有后备驱动程序的 nouveau DRM。xf86-video-modesetting我目前在 x.org 中遇到一个问题，我的鼠标将卡在显示器左上角距 (0 ,0)。当我运行时xev -root，我仍然看到注册的鼠标移动，并且我可以看到鼠标光标实际上发生变化（从光标到工字骨再到手套），因为它应该取决于它“悬停”的内容。鼠标本身仍然可用，因为我可以像平常一样单击/右键单击事物（我必须根据选择的文本、鼠标悬停时聚焦的窗口等来“猜测”鼠标位置）。

我可以有一个空的 xorg.conf 或由 nvidia DRM 配置的 xorg.conf，所以这是可以忽略不计的。不过，我会继续发布我的 xorg.conf

编辑：这种行为实际上与没有驱动程序的普通架构安装相同nvidia。
