How to start linux with gui without monitor?
提问by smarthand
I met a problem. I had a server which is installed redhat enterprise 5.5. And one Qt program was running on this server. So what I should do is to turn on my server, the server will start automaticly with Gui and that Qt program will start automaticly. I finished all on my desktop. But while I start this server without monitor, we know server was running without monitor,the X server go bad.God, what should I do?
我遇到了一个问题。我有一台安装了 redhat Enterprise 5.5 的服务器。一个 Qt 程序正在这台服务器上运行。所以我应该做的是打开我的服务器，服务器会自动启动 Gui 并且 Qt 程序会自动启动。我在桌面上完成了所有操作。但是当我在没有监视器的情况下启动这台服务器时，我们知道服务器在没有监视器的情况下运行，X 服务器坏了。上帝，我该怎么办？
Here is the xorg log:

I searched on internet,somebody told me that I should add nomodeset in the end of the kernel line in /boot/grub/grub.conf.I did it but nothing changed. Can anybody tell me what should I do?
我在互联网上搜索，有人告诉我应该在 /boot/grub/grub.conf 的内核行末尾添加 nomodeset。我做到了，但没有任何改变。谁能告诉我我该怎么办？

Your problem is that the X server checks whether there is really a monitor attached. Your options:
您的问题是 X 服务器检查是否真的连接了监视器。您的选择：
Attach a monitor. Simple but wasteful.
Use Xvnc instead. This is like X but it renders to memory, so it doesn't need a graphics card (and no drivers) and no monitor. You can even connect to it remotely via the VNC protocol.
连接显示器。简单但很浪费。
请改用 Xvnc。这与 X 类似，但它渲染到内存，因此它不需要图形卡（也不需要驱动程序）和显示器。您甚至可以通过 VNC 协议远程连接到它。
The second option is actually pretty simple to implement: Just call vncserver :42
第二个选项实际上很容易实现：只需调用 vncserver :42
After export DISPLAY=:42, you can run your Qt application and it will connect to the virtual Xvnc server running on the virtual display 42 (0 is the default).
之后export DISPLAY=:42，您可以运行 Qt 应用程序，它将连接到在虚拟显示器 42 上运行的虚拟 Xvnc 服务器（默认值为 0）。

Restart the X server, open a tty window (alt + f1) or (alt+f2) then login on the terminal and run 'startx'. Otherwise try ssh-ing to the server and either attempt startx or reboot the machine.
重新启动 X 服务器，打开 tty 窗口 (alt + f1) 或 (alt+f2) 然后登录终端并运行“startx”。否则，尝试通过 ssh-ing 连接到服务器，然后尝试使用 startx 或重新启动机器。
