I have a Acer netbook with Intel gma 3600 graphics. Yesterday I installed cedarview graphics driver after reading this post.

Now, I have been observing that after I installed the driver my system seems laggy like pdfviewer hangs while scrolling, chrome hangs, and some other similar issue which I believe were not present before I installed the driver.

Earlier my netbook was using the default graphics driver that came with ubuntu 12.04(kernel generic-pae 3.2).

So, is there any way I can restart my XServer without the cedarview driver and check if I am facing the similar issues there also or I have to manually uninstall the drivers(cedaview).

If you all suggest to uninstall it than sudo apt-get --purge remove cedarview-drm libva-cedarview-vaapi-driver cedarview-graphics-drivers && sudo update-grub2 is the correct way to uninstall it?
