When I final discovered there is a memory leak in glx (?) relating it back to the Nvidia drivers (BUG/565981 Report) Apparently the ATI driver has been fixed now and hopefully the Nvidia soon. I use the Terminal command "ps ux" to watch the CPU% slowly climbed to 100% over a short period of time. I installed older and current versions of each OS all w/o real success. I've installed Ubuntu 10.04 and Mint 9 on old then new HDs thinking it was drive related. I spend 30 hours since trying to better understand this issue. Changing the frequency also gave false hope of a fix. My last entry (#79) I suggested fix turned out to be short lived. I hope this helps developers with debugging. Also graphs updated in 10 sec intervals are not so useful, but it seem to me that it is somehow interpolating the values for graphs between 10sec updates or the update interval is is incorrect (as snibgo wrote on ) - 12 or 13 sec caused graph to move approx. If I use update interval of 5 or 10 sec overall CPU usage gets lower but on System Monitor panel applet I can see that there are still spikes utilising 40-50% of one CPU core=It still uses too much resources, especially considered that between the spikes CPU usage is 20-30%. In maximized window (size 1647x1000 px) graphs start to lag after 20 or 22 sec with 100% CPU usage on one core. Resource consumption doesn't depend only on graph update interval, but also on graph size if I unmaximize the System monitor window (to size 550x412 px - lowest possible) graphs are smoothly running (without lags and with 90-100% CPU usage on one core) even if I let it run for 60+ sec=whole interval is used for graph.
