If you’ve used Linux for any amount of time, you’re already familiar with the Ctrl+Alt+Backspace shortcut key combination that restarts X Windows immediately… but have you ever wondered if there is a way to disable that behavior?

如果您使用Linux已有一段时间，那么您已经熟悉Ctrl + Alt + Backspace快捷键组合，该组合键可以立即重新启动X Windows……但是您是否想知道是否有办法禁用该行为？

Turns out it’s extremely simple to do, although I’m not necessarily recommending that you do this… it’s more for informational purposes. *(while Linux might be rock-solid, I’ve had more than my share of crashing in Gnome, so the shortcut key is useful)*

事实证明，这样做非常简单，尽管我不一定建议您这样做……它更多是为了提供信息。 *(尽管Linux可能固若金汤，但我在Gnome中遇到的崩溃更多，所以快捷键很有用)*

The first thing you’d probably want to do is make a backup of the xorg.conf file, which you can do with this command:

您可能要做的第一件事是对xorg.conf文件进行备份，您可以使用以下命令进行备份：

> sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig
> 
> 须藤cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig

Then you can edit the xorg.conf file by using Alt+F2 to open up the Run dialog and using the following command:

然后，您可以使用Alt + F2打开“运行”对话框并使用以下命令来编辑xorg.conf文件：

> gksu gedit /etc/X11/xorg.conf
> 
> gksu gedit /etc/X11/xorg.conf

Now go to the bottom of the file and look for a section called “ServerFlags”, which might not exist. If the section does not exist, add this to the bottom of the file:

现在，转到文件底部，查找可能不存在的名为“ ServerFlags”的部分。 如果该部分不存在，请将其添加到文件的底部：

> `Section "ServerFlags" Option "DontZap"  "yes" EndSection`
> 
> `Section "ServerFlags" Option "DontZap" "yes" EndSection`

If that section does exist, then just add in the option line:

如果该部分确实存在，则只需添加选项行：

> `Option "DontZap"  "yes"`
> 
> `Option "DontZap" "yes"`

You’ll have to restart X again, the easiest way is ironically by using Ctrl+Alt+Backspace… but at that point the shortcut key won’t be active anymore.

您将不得不再次重新启动X，最简单的方法是使用Ctrl + Alt + Backspace…具有讽刺意味的是，但是此时快捷键将不再有效。

If you somehow managed to totally screw up your system by making this change, you can copy the xorg.conf.orig file back to xorg.conf to switch back to the original configuration.

如果通过某种方式设法完全破坏了系统，则可以将xorg.conf.orig文件复制回xorg.conf，以切换回原始配置。
