In System Info in 11.10, the graphics driver wasn't detected. I use ACER Aspire 4750 with Intel Core i3-2340M and Intel HD Graphics 3000 graphic card

How to install the driver for my Ubuntu?

go to the Intel Linux Graphics website. This is the original Intel website and not a third-party. Look around and see what You can find. And here is the link for the latest driver available. – Shahe Tajiryan Dec 12 '11 at 10:06

The Intel cards are automatically detected and installed in Ubuntu, no need to install further drivers. See this question if you want them to be recognised in System Info.

However, if you feel that you want to install a more recent driver (I dont recommend this if you do not know how to recover from a broken graphics driver) you can add the xorg-edgers fresh X crack PPA and update your system with the packages from there.

To do that open a terminal and use these commands

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update && sudo apt-get upgrade

Reboot with

sudo reboot

Again, do this only this with extra caution!

If you don't want the bleeding edge in drivers, you can also use the x-swat PPA, which contains more stable drives.

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update && sudo apt-get upgrade

This is a more appropriate answer for most people I think. – Magpie Mar 30 '13 at 18:19
