Installing Intel graphics driver in Ubuntu 16.04

I have a dual Intel 6th gen./AMD Radeon HD graphics, and I have recently upgraded to Ubuntu 16.04 LTS. I was prviously on Ubuntu 14.04, using Intel graphics driver in Ubuntu 16.04, installed from here:

https://download.01.org/gfx/ubuntu/14.04/

Video acceleration worked just fine in VLC in 14.04. But, now I have several issues with video acceleration, including the inability to scale the video. So, I want to use graphics drivers provided by Intel, but unfortuanately there is no prebuilt packages for 16.04 in 01.org repositories. What should I do?

Another issue is that I no longer see propertiary drivers in "additional drivers" section of the "software and updates" utility. Is it because I am using newer kernels? Previously I could be able to see AMD propertiary drivers, and install it if I wanted, which I once did for testing, and then returned to Intel graphics.

PS: In the list provided here, I have a Gen6 Intel GPU. I have installed the 15.04 binaries, and this is the output from vainfo:

PS2: The problems with VAAPI support on Intel drivers seem to be widespread. For example, see these:

Solution 1:

Update 30 Aug, 2016: Latest drivers from Intel are now available

Default installation Ubuntu 16.04 should work somehow fine. Intel drivers are included in the default installation of Ubuntu 16.04 with Linux 4.2 kernel, and you the hardware acceleration works in VLC if you choose "XCB" output. But this is not the latest drivers from Intel. Here we read:

• u16.04 already contains the latest intel driver that has passed full QA
• There is no point in installing the u15.10 updates on u16.04 - even if you succeeded it would be a downgrade

Recent update:

Recently, Intel released Intel Graphics Update Tool 2.0.2 which supports Ubuntu 16.04. Download it from here:

Solution 2:

I had the same problem. I have solved it by install intel driver like below (i think it's a part of the solution ;-) ) AND chose the GLX video output in VLC setting.
