我正在尝试在配有 Gigabyte H270 芯片组主板和 i5-6400 的机器上安装 16.04 Ubuntu Server。服务器安装运行顺利，没有任何问题。
第一次启动时，尝试加载 VESA VGA（不记得具体是哪一行）后屏幕变黑。我可以启动到 nomodeset shell。在那里我安装了 xorg 和 gnome 以及 gnome 系统工具和 gnome 应用程序安装（按照我们用于略有不同的机器的手册）。另一次重新启动产生了相同的黑屏，现在甚至 nomodeset shell 也无法工作，因为屏幕以 2 秒为周期闪烁。通过 root 恢复 shell 安装 openssh-server 后，我可以通过 putty 从网络上的另一台机器登录。
以下信息部分基于此处的类似主题： Skylake 集成显卡在 15.10 上无法运行
通过 putty，我试图找出问题所在。dmesg | grep -i i915 给了我一堆信息。警告和 1 个错误。有趣的东西：
[ 5.557010] [drm:vlv_enable_pll.isra.85 [i915_bpo]] *ERROR* DPLL 0 failed to lock
[ 7.305174] i915_bpo 0000:00:02.0: No connectors reported connected with modes
另外 lshw -enable pci -class display 产生：

因此图形驱动程序未加载，显示器未被认领。可能是因为我处于终端仅有的 putty 会话中？inxi -b 告诉我：

我不确定哪里出了问题。X 服务器似乎根本没有运行，因为 /var/log/ 或 ~/.local/share/xorg/ 中没有日志。
真的不确定出了什么问题...有人能告诉我如何调试它吗？
