X11-Treiber neu installieren Ubuntu 14.04

Nach einem kürzlich erfolgten Upgrade von 12.04 auf 14.04 würde der xserver auf meiner Workstation nicht mehr gestartet. Beim Laufen

startx 

Der folgende Fehler tritt auf:

(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. 

Ich vermute, dass die X11-Treiber nicht neu aufgebaut wurden. Ich bin jedoch ratlos, da ich mit diesen Schritten nicht vertraut bin. Ich habe die Xorg-Protokolle geprüft. ihr Inhalt ist:

Durch die Neuinstallation der Nvidia-Treiber wird dieses Problem nicht behoben. Wie kann ich die X11-Treiber neu erstellen?
