latest kernel update (.38) doesn't boot in 3D

Question

I'm using ubuntu 12.04 with Nvdia GE-F card (happily working and installed using these instructions). Since the last kernel update (3.2.0-38-generic) i can only boot in 2D mode (otherwise it just freezes moments after i log in).

Is there a way to un-roll an update? I need my machine....

Answer 1

From grub you should be able to choose to boot to previous versions. You will then have a list of choices with all the previous kernels.

I just followed these instructions to remove a kernel I didn't want.
