最近从 12.04 升级到 14.04 后，xserver 无法在我的工作站上启动。运行
startx
出现以下错误：
(EE) module ABI major version (6) doesn't match the server's version (8)
xinit: connection to X server lost
waiting for X server to shut down (EE) Server terminated successfully (0). Closing log file.
我怀疑 X11 驱动程序尚未重建。然而，我不知所措，因为我不熟悉这些步骤。我检查了 xorg 日志；它们的内容是：

重新安装 Nvidia 驱动程序无法解决此问题。我该如何重建 X11 驱动程序？
