I have been using Ubuntu since Hardy Heron (8.04). I used Natty, Oneiric with Unity. But When I recently (more than 1 month now) upgraded My Ubuntu to Precise (12.04), the performance of my laptop is not satisfactory. It is too unresponsive compared to older releases.

For example, the Unity in 12.04 is very unresponsive. Sometimes, it requires 2 seconds to show up the dash (which was not the case with Natty, though people always saying that Natty's version of Unity is buggiest). I am assuming that, May be my 1GB RAM now becomes too low to run Unity of Precise. But I also think, Since Unity is improved in Precise, It may not be the case. So, I am not sure.

Do you have any ideas? Will upgrading RAM fix it? How much I need if upgrade is required?

Laptop model: "Lenovo 3000 Y410"
Graphic : "Intel GMA X3100" on Intel 965GM Chipset.
RAM/Memory : "1 GB DDR2" (1 slot empty).
Swap space : 1.1GB
Resolution: 1280x800 widescreen
Shared RAM for Graphics: 256 MB as below output suggests

$ dmesg | grep AGP
