I am trying find out if you can install updated drivers for Intel 3000 HD graphic card. I'm been hearing Intel graphics don't really have proprirtory drivers and they are open source versions. Then, how can I improve my graphics with my current graphics card?
I really recommend you stick with the default driver that comes with the kernel.
If you feel adventurous, you can install the latest drivers from the edgers ppa.
This is really experimental and you should only use it if you know how to recover from a broken graphics driver.
first install ppa-purge in case something goes wrong
add the xorg-edgers ppa
refresh package list and switch to new driver
If this messes up your system and you want to revert back to the offical driver run:
If you are greeted with a completely unusable display press Ctrl-Alt-F1 or F2 I always forget which one, to open a console and run the ppa-purge command.

Now you can get intel graphics from their open source site which has instruction on installation there. Once you have run the software it is advised you use synaptics or apt-get for updates.
