I have the same problem on 12.04 x86_64, kernel 3.2.0-34-generic #53-Ubuntu SMP on HP ProBook 6560b. System freezes completly
But: 1. Some time ago I was lucky enough to connect via SSH and run top (I think that PC was'nt freezed completely). I saw X process with 100% CPU. After few minutes box hanged (no ping etc.). 2. I have 3 installations of Ubuntu 12.04 x86_64, but I have problem on HP ProBook 6560b only. 3. First time I've faced this problem after Aug., 15 or so. 4. System hangs on screensaver, even when I'm using blank screen instead of OpenGL screensaver It seems that this is hardware-dependent problem.

No other TTYs can be started. Mouse doesn't move. Keyboard doesn't react. The only solution is hard reset. Seems to happen on a variety of configurations, including nVidia, ATI and Intel graphics. If you are still able to TTY or SSH into other sessions, move the mouse or use the keyboard, file another bug. Thx. Joris V. (brains). Update: 5/21/2012 Updating the kernel to 3.3.6 as suggested by Michael in #91, the system seems stable, no freezes yet in 5-6 hrs of using and watching videos for couple of hrs. Original description: I recently installed newly released ubuntu 12.04 LTS 64 bit version on my desktop. And it is frequently freezing, for the first few hours it ran smoothly and when I started watching videos it started freezing randomly. I have to use hard restart every time. Initially it was only during videos but now even during normal browsing it is freezing. I am using on board graphics and do not have any graphics card installed. Can someone please help me here, I really love the new looks of 12.04 and it bugs me not being able to use :( Below is my hardware configuration: Processor: Intel CORE i3 processor (2nd generation) Board: Intel® Desktop Board DH67BL Ram: 4GB Graphics: On board HDD: 500 GB Please let me know if you need more information, or any specific logs I can capture (and how).
