内核升级至 3.19.0-18 后“启动版本 219”

今天内核从 3.19.0 升级后16至 3.19.0-18lightdm 无法启动。

GPU 驱动程序是从“软件和更新”的“附加驱动程序”选项卡安装的 fglrx。

尝试通过运行启用服务

sudo systemctl enable lightdm.service -f

由于服务启动失败，因此无济于事。请参阅系统日志：

选择以前的 3.19.0-16 内核的 grub 启动选项 - 系统正常启动。

请问如何修复？

今天，在下一组内核更新之后，问题已经消失。现在 Ubuntu 15.04 可以正常启动。

sserg@SSERG-U38DT:~$ inxi -F
System:    Host: SSERG-U38DT Kernel: 3.19.0-18-generic x86_64 (64 bit)
           Desktop: Unity 7.3.2  Distro: Ubuntu 15.04 vivid
