I have a new install of 11.10 32-bit with gnome classic on a brand new thinkpad L520, Sandybridge Core i5, 4GB RAM,
Observation 1:
I was browsing through chrome when my system seemed to be seriously lagging, so I killed chrome to see if it gets any faster. But there remained no difference. Notice that CPU usage was a bit strange here. It showed no high activity, but as soon as I would click on applications in gnome panel, it would shoot CPU usage to 70, or 80 or 90 or 143% etc. depending on how quickly i clicked back and forth. At this instance I removed by AC adapter of my laptop, and suddenly system got fine. So i again clicked on gnome panel, and noticed that it now took only 7% or 12% or 13% at max, with same kind of clicks in application menu.
Observation 2:
At the other times, with AC adapter plugged in, top indicates four instances of chromium taking 90%, 60%, 47% and 2% (for example), and then once I take out the AC adapter same processes take lesser CPU all of a sudden
Intermediate conclusions:
What does this indicate ? I cannot figure out any "other" process in "top" that is suddenly being triggered. Infact it is the same process that hogs up my CPU once AC power is plugged in !
NOTE: the problem is now CONFIRMED, as i can recreate it whenever I have power adapter plugged in !
Looking eagerly for debugging help to get going with ubuntu 11.10
