10.10 on i7 2.8GHz, 4Gb Ram, 4Gb swap,
All of sudden system acting like freezing down.
No heavy things running, Chrome with about 5 tabs open.
Could not find any clue by looking at top or processes, memory are fine, could it be hard drive access problem?
It seems happening more often when waking up from an idling of a couple minutes. Most of time the 2nd monitor goes dark. After CPU burst passes, everything comes back to normal.
Can any one please give me some hint on how to troubleshoot this?
Reinstall or upgrade is definitely out of the question at this moment.
