我有一个配置为无头运行的 Ubuntu 12.10 Box。我已经通过大量的试验和错误成功地启动了 X headless，但仍然有一个小故障：
当使用显示器启动时，一切正常，宽屏分辨率等等，当启动无头时，它将坚持 4:3 分辨率，我怀疑这与 vesa 驱动程序有关。
眼镜：
- 显卡 intel HD 4000（i7 集成）
- ubuntu 12.10（最新更新）
这是我的 /etc/X11/ xorg.conf：

答案1
如果您只想无头，有一个更简单的方法可以做到这一点：不要使用标准 X 服务器。
我经常在几乎从未连接显示器的盒子上这样做。这个例子在 debian 上使用 xdm，但我已经使用 kdm 和 gdm 完成了。
将 Xvnc 指定为要使用其完整路径的 X 服务器，并在命令行上指定分辨率。例如，这是来自无头盒子的我的 /etc/X11/xdm/Xservers 之一。
:0 local /usr/bin/Xvnc :0 -nolisten tcp -desktop crystal:0 -geometry 1400x1050 -rfbauth /home/ben/.vnc/passwd
为了让事情变得更好，我创建了 /etc/X11/Xsession-0
#!/bin/sh
#
vncconfig -nowin &
# invoke global X session script
. /etc/X11/Xsession
并将以下行添加到 /etc/X11/xdm/xdm-config
DisplayManager._0.session: /etc/X11/Xsession-0
在（并且仅在）所有已知的 Xvnc 实例上自动启动 vncconfig。在混合本地远程设置中，我使用两台 X 服务器，一台传统服务器，一台虚拟服务器。奇迹般有效。不幸的是，这对于当前超级用户友好的显示管理器来说更加困难，因为他们太努力让事情变得简单。
答案2
使用xrandr您可以定义新的模型行。这行代码来自我的，~/.xinitrc它在每次 X 会话启动时运行。这明确定义了可应用于任何输出的 1280x720 60Hz 模式。
xrandr --newmode "1280x720p" 74.25 1280 1320 1376 1650 720 722 728 750
然后应用它（也可以通过.xinitrc永久会话自动应用）：
xrandr --addmode HDMI1 "1280x720p"
xrandr --output HDMI1 --mode "1280x720p"
当然将其更改HDMI1为您的实际输出。即使输出没有连接显示器，它也能工作。
