VirtualBox4.2 杀死 lightdm

我刚刚在 Ubuntu 13.04 上安装了 VirtualBox4.2。当我打开 VirtualBox 时，一切似乎都很好，直到我尝试创建一个新的 VM，此时 lightdm 崩溃，我被迫（最终）返回登录屏幕。

有人在 Ubuntu 13.04 上运行 VirtaulBox 并遇到同样的问题吗？有人知道如何修复吗？

以下是看似相关的dmesg信息

打开以下文件

sudo vim /etc/apparmor.d/sbin.dhclient

在该文件中查找以下条目

/var/lib/NetworkManager/dhclient-*.conf lrw,

用这一行替换它

/var/lib/NetworkManager/dhclient*.conf lrw,

然后重新启动

reboot
