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?

Did you see that? System does not have proper nvidia driver. It's running in VGA mode. That's why system is not responsive. Open jockey-gtk (default installed), it will automatically show perfect driver for your graphics card. Install it from there. And also remove your existing driver first.

During installation, how much swap partition did you create? Use ubuntu-tweak janitor to clean and cool your Ubuntu and update Ubuntu using update-manager.
