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?
