After the upgrade my system spikes,lags ,delayed performance than ever. But previous Ubuntu 10.04 works great without any problems.
My configuration : Intel p4 3 Ghz ,1 Gb RAM , On-board ATI Express 200 Graphics.
What is the reason for this kind of performance issues?
Now i am using Linuxmint 11 until the problem get solved , But i still wants to use Ubuntu 11.10
