我正在尝试构建 Xorg X Window 系统环境，如 Beyond Linux From Scratch Version 8.0 中所述。我的 BLFS 系统驻留在使用 VirtualBox 版本 5.0.10 r104061 的虚拟机中。
我按照第 24 章 X Window 系统环境中概述的步骤进行操作。然而，当我完成安装并尝试 startx 时，我得到了以下输出：-

<*> DRM driver for VMware Virtual GPU [CONFIG_DRM_VMWGFX]
[*] Enable framebuffer console under vmwgfx by default [CONFIG_DRM_VMWGFX_FBCON]
和

在这两种情况下都得到相同的错误消息。这是图形适配器 lspci 的输出

知道为什么屏幕无法加载吗？

我在这里发布的答案可能会有所帮助：设置 vnc 服务器且无物理显示器：Ubuntu 16.04 LTS
它为 X 堆栈设置一个虚拟屏幕来发送输出，让它完成 GUI 环境的启动。
