I would not duplicate any thread but here the stuff is rather obscure. I'm a not so clever linux user even if I used it since many years, but at a user level, not guru.
The last distro I've used without (important) problems is the 13.10.
Few days before this Christmas I decided to move toward the 14.10, first upgrading to 14.04 with the normal upgrade procedure, when my PC started to show anomalies at the boot.
The main behavior is: boot -> login screen and the whole thing freeze up. No way to use keyboard nor mouse or trackpad. Or (alternative behavior) login with success, then newly login page (I tried to put a wrong password and the login behave correctly, saying password incorrect)
I was able to do a full backup and then I decided to try to install from scratch Ubuntu 14.04 from CD (it was not so easy because more and more time the install sequence hanged on) and now I have a 14.04 working only in recovery mode.
I attach a syslog file containing the histories of 3 boots, each one with different warnings/errors, hoping this could be enough to understand where the problem is. I can add information as needed.

I don't know what to do anymore, I hope to find some enlightening hint from you. Thank you in advance.
