Recently I needed to update integrated Intel graphics drivers to gain access to more recent OpenGL extensions. Packages available by default in base system do not provide such functionality, so I used Updated and Optimized Open Graphics Drivers as it is built almost simultaneously with the latest updates.

Recent information is provided by Mesamatrix.

Installation

Add oibaf/graphics-drivers PPA repository.

$ sudo add-apt-repository ppa:oibaf/graphics-drivers

Update package list.

$ sudo apt-get update

Install updated packages.

$ sudo apt-get upgrade

Additional information

There was a huge progress in recent months. All I can say is big thanks!
