My laptop works perfectly fast with Windows 7 but is very slow in Ubuntu 12.04.When I try to open the dash it takes 1-2 sec.even the normal right click on the desktop for the dropdown options is taking time.I installed preload but it made a very slight change. Everything is up to date.

My laptop is : Lenovo ideapad Z560
500 GB hard drive (dual booting win7 and Ubuntu 12.04)
3 GB RAM
Intel® Core™ i3 CPU M 370 @ 2.40GHz × 4 processor
Nvidia GeForce 310M/PCIe/SSE2
Ubuntu 32 bit

any help?

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
