My system specification is as follow:-
Microprocessor 2.6 GHz Intel Core i5-3230M
Video Graphics Intel HD Graphics 4000
I want to install graphic driver provided by intel for linux. Need help regarding installation of drivers.
The official Intel Linux Graphics Installer is now no longer supported for 12.04 (support for 13.04 will end when 13.10 is released).
Near the bottom of this link, it is said that:
Unless you have a specific reason for using the latest drivers, your system should work fine with the default drivers.
You could manually add the 12.04 repo (it's still hosted here), but it will not be updated to the latest version and may be removed without notice.
Adapt the instructions here if you still want to use the outdated 12.04 repo
Download the Intel Graphics Installer from the 01 website https://01.org/linuxgraphics/downloads
