Boot delay and mouse lag at login after Ubuntu 12.04 update

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?

apt-get upgrade does not normally upgrade the kernel - you need apt-get dist-upgrade to do that.

First, disable the boot splash/plymouth by editing /etc/default/grub and removing "quiet splash", changing this line to GRUB_CMDLINE_LINUX_DEFAULT="". This will better let you see any errors/warnings during the boot process.

In any case, it is simple enough to go back to the previous one and see if the problems go away -- at the grub selection menu, select "Previous Linux Versions" (screenshot 1) and then select the top entry (screenshot 2). Note that the exact kernel names may not be the same for you!
