我最近将 Ubuntu 操作系统从 14.04 更新到了 14.10。我在一台启用了 Optimus 的笔记本电脑上运行,配有 Intel 4000 显卡和 nVidia 640M。

当我将 mini-DisplayPort -> VGA 适配器插入外接显示器时,Ubuntu 会尝试扩展我的桌面。图像现在出现在两个屏幕上,但图像本身看起来像单个屏幕的严重扭曲视图。当我尝试按下屏幕内的任何内容时,它不会按下,可能是因为实际屏幕与显示内容的映射已关闭。但是,我可以正常按下两个屏幕右上角的设置图标。此外,登录屏幕在双屏模式下运行良好。我的主显示器(内置)是 1920x1080,而我要添加的显示器是 1600x1200。有人有什么建议吗?到目前为止,我已经重新安装了所有 nVidia 驱动程序。
