Ubuntu 12.04 desktop freezes randomly
Note: I see a lot of similar "Ubuntu freezes randomly" questions already posted here, and have 2 things to say about that:
None of these questions (unless you can correct me with a specific example) are identical to my question and scenario here (with FF)
None of these questions have a sufficient answer as to how to troubleshoot/diagnose the underlying problem.
For those 2 reasons, for any user to mark this question as a duplicate, I would first ask that you provide an exact reference to the question you believe this is a duplicate of!
Moving along...
Ever since I switched over from Windows 7 to Ubuntu 12.04 last November, I've experienced a recurring issue that I'm finally fed up with and want to resolve.
Every once in a while, without any warning or discernible pattern, my whole Ubuntu machine freezes; the system clock in the upper-right corner stops ticking/moving, all open applications are frozen and cannot be interacted with, the mouse cannot be moved, etc. The only fix thus far has been to restart.
The only common pattern that I think is a solid suspect is the fact that I believe that Mozilla Firefox (v. 20) is open and running almost every time this happens, if not every time. It happens if I leave my machine running over night (and FF is also running), and sometimes it happens while I'm actively using FF (clicking a link, doing some DOM operation, whatever).
I'd like to attack/solve this problem from both the OS- and application-perspective. I'd like to know what logs (for both Ubuntu and FF) I could start looking in for warnings, errors or failures. Also interested in what the community's input/feedback is and if there are any other suggestions for debugging. Thanks in advance!
