Xorg.conf 未改变显示方向

Question

我目前在 346.46 上使用 Ubuntu 15.04 和 GTX 570。我有一个 2560x1440 的显示器，右边有一个 1080x1920（纵向）的显示器。我使用 i3 作为窗口管理器。在 Unity 中，显示器似乎使用 Ubuntu 的显示设置正确设置；这个问题确实发生在 gnome、i3 和登录屏幕（Ubuntu 默认）。我曾经nvidia-settings修改布局并生成一个xorg.conf，它确实位于/etc/X11/xorg.conf。其内容如下

尽管该文件似乎确实被写入了正确的错误，但是当我使用 nvidia-settings 写入时出现以下错误：

Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found
Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable

当我重启电脑时，纵向显示再次恢复到默认配置（横向）。这个问题可以通过使用nvidia-settings并将所有内容设置为相同的值来解决，尽管我认为这应该由 X11 配置文件来解决。

我还收到一个系统错误，提示我的 nvidia 驱动程序不是 Ubuntu 包，这似乎是在通过 从 14.04 升级到 15.04 后出现的do-release-upgrade。
