upgrade from 11.10 to 12.04 and nvidia

[vovotux]

First, I apologize for my poor english. I'm using babelfish to translate from portuguese to english.
I'm using kubuntu 11.10 and I intend to upgrade to version 12.04.
My video card is a onboard NVIDIA GeForce 7025/nforce 630a and after update nvidia driver to 295.40 version kde freezes when loading, making graphical desktop environment unusable on Arch Linux. The same happened on Sabayon 8.
A search on google demonstrates that this is truth on other distributions and desktop enviroments.
Actually, nvidia module on my system is 173, but jockey recomendation is nvidia current. So, on upgrading to kubuntu 12.04, nvidia driver will be automatically updated to current? Must before revert driver to nouveau?

You can revert to the old driver after you upgrade. See post #10 in this thread:

Before start this topic I had seen that thread but unfortunately I did not give attention to post 10. Thanks for your help and excuse me for unnecessary thread.
