I can confirm this. We have applied the latest updates to few laptops and those experiencing crashes. Sometimes the whole computer freezes (we have to hard reset the system) while sometimes the window manager crashes but the system is still responsive. There is no information in the syslog when system freezes but when the window manager dies you get the following outout in the syslog(attached as sys.log). The updates updated the intel video driver to the following version 2:2.17.0-1ubuntu4.3 Other laptops which has no updates applied are running the following version 2:2.17.0-1ubuntu4.2 I have also tried to backport the intel driver to 2:2.17.0-1ubuntu4 version ( i couldn't find 2:2.17.0-1ubuntu4.2) in theory this should work but still having same problems.
I have tried briefly unity2D which looked promising. Please let me know if you need more info.

I have Ubuntu 12.04 LTS and it freezes all of a sudden. The keyboard/mouse stop working. Can't open any other TTY. The only solution is a hard reboot from button. Configuration: Description: Ubuntu 12.04.2 LTS Release: 12.04 Lenovo ThinkPad Edge Laptop Intel® Core™ i5-3210M CPU @ 2.50GHz × 2 OS-type: 32-bit 4GB RAM VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) VGA compatible controller: NVIDIA Corporation Device 0de9 (rev a1) I have installed on it a basic LAMP configuration, plus netbeans 7.2, FileZilla 3.5.3, Google Chrome. I also have an external monitor (I mention it because there was another bug similar that was saying that the monitor is the problem, but mine freezes regardless if I use or not the monitor) I don't think there are any logs as the system freezes without any warning (no CPU overheating, no lag...) It doesn't matter how many programs I have opened, because it freezes even if I close all programs, or even if I have Netbeans, Chrome(10+ tabs +youtube), FileZilla, messenger, libre office, remmina and music on all in the same time. Sometimes it crashes as soon as I start using a program, other times crashes 2,3 times one after another on restart, and other times it doesn't crash for days (the longest period without a crash is for 3-4 days). What is even more strange is that I have another laptop with Ubuntu ( a Dell Inspiron), with same software configuration and external monitor, and it never crashed. The only software difference is that the one that doesn't crash I downloaded the OS from ubuntu.com, and for the one that crashes I took the OS from a Romanian proxy. Could these be the issue? Please tell what log files to upload that may be of any help.
