lag

I am facing these weird problems after updating Ubuntu 12.04 with apt-get update && apt-get upgrade:

It takes too much time to come to the Plymouth theme after selecting Ubuntu from the grub menu. Is it possible to correct this?
On the login screen, before entering the password, whenever I move the mouse, it is kind of lagging/stuck. Only after entering the password and pressing Enter, it works normally.

I think this may be because of the updated kernel.

If so, is it possible to downgrade the kernel to the previous one ? If that is not the reason, what can be the problem?

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
