Update killed Xserver--again

So I did a recommended update with the Xfce dt and yet again the nvidia driver update killed the system to were I can only log in to the CLI. How can I fix this and how can I ensure that the next update doesn’t break it again?

Currently we have these drivers available:

nvidia repository : core
Stable : 460.73.01-1
Testing : 465.27-1
Unstable : 465.27-1
