如何在没有监视器的情况下使用gui启动linux? [英] How to start linux with gui without monitor?

问题描述

我遇到了一个问题. 我有一台安装了Redhat Enterprise 5.5的服务器. 这个服务器上正在运行一个Qt程序. 因此，我应该做的是打开服务器，该服务器将使用Gui自动启动，并且Qt程序将自动启动. 我在桌面上完成了所有工作. 但是当我在没有监视器的情况下启动此服务器时，我们知道服务器在没有监视器的情况下运行，X服务器变坏了.上帝，我该怎么办?

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?

这是xorg日志:

我在互联网上搜索，有人告诉我，我应该在/boot/grub/grub.conf的内核行末尾添加nomodeset. 谁能告诉我该怎么办?

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?

推荐答案

您的问题是X服务器检查是否确实有监视器连接.您的选择:

Your problem is that the X server checks whether there is really a monitor attached. Your options:

1. 安装显示器.简单但浪费.

1. Attach a monitor. Simple but wasteful.

改用Xvnc.就像X一样，但是它渲染到内存中，因此它不需要图形卡(也不需要驱动程序)和监视器.您甚至可以通过VNC协议远程连接到它.

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.

第二个选项实际上很容易实现:只需调用vncserver :42

The second option is actually pretty simple to implement: Just call vncserver :42

在export DISPLAY=:42之后，您可以运行Qt应用程序，它将连接到虚拟显示器42(默认值为0)上运行的虚拟Xvnc服务器.

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).
