以下是我安装和运行 Ubuntu 15.04 时遇到的一些问题的有趣探讨...
在我的（台式）机器上，我的主板（DVI + VGA）和显卡（Geforce GTX 960、DisplayPort + HDMI）都有视频输出。我（通常）不使用主板的视频输出；所有视频都应该来自显卡。我在一个硬盘驱动器（SSD）上安装了 Windows 7；我想使用带有 Ubuntu 15.04 的 USB 引导程序在单独的硬盘驱动器（SSD）上安装 Ubuntu 15.04。
当我使用 USB 引导程序启动 Ubuntu 15.04 时，Ubuntu 只会在主板上查找视频输出，而不是视频卡。这很烦人，原因如下：
我的显示器甚至没有 DVI 或 VGA 输出（必须找到 HDMI -> DVI 电缆），
没有迹象表明 Ubuntu 没有使用我的视频卡的输出（因此弄清楚发生了什么很痛苦——尽管我猜 Ubuntu 启动声音仍然在播放。
Ubuntu 无法/没有检测到它应该使用我的显卡进行输出显示，这有什么原因吗？Ubuntu 似乎应该能够提供或使用一些“通用”显卡驱动程序，这些驱动程序足以确保显卡的视频输出正常。
好的，接下来是下一个问题——在经历了整个混乱之后，我终于可以安装 Ubuntu 15.04 了。但是，当我尝试启动 Ubuntu 时，显示服务器 ( xserver) 无法初始化。日志似乎表明它xserver因空指针异常而崩溃。（抱歉，我没有崩溃日志——当我只有一个终端，并且系统上的其他硬盘似乎都无法挂载时，很难复制这些日志。但是，我可以使用例如 . 来访问终端Ctrl + Alt + F1）。
我在 Ubuntu 14.04 LTS 中没有看到这个问题，所以暂时回滚到了那里，但是对于为什么会发生这种情况，您有什么想法吗？
编辑：虽然我能够通过更新内核来解决这个问题，但我想无论如何都要发布启动日志+崩溃转储（删除时间）：
