Since installing Ubuntu 12.04, I am experiencing low performance on graphic programs, including video playbacks, etc.
As I have checked the intel driver of mine is already at its latest version. It's really occuring meanwhile playback of videos or web-flash videos (youtube, etc) OS is being logged out automatically and just display an error reporting of Xorg windows for me. I can not actually playback hd videos with the normal frame rate as well. here are some initiation of my graphic card details :
