New Intel graphics cards & BunsenLabs

(I should have included "Skylake" in the title but I couldn't resist the alliteration)

For users of brand new Intel machines, the standard BunsenLabs kernel, video drivers and mesa package offer limited support and poor performance.

Fortunately, newer versions of these are available from the stretch-backports repository.
http://backports.debian.org/

Install these with the following commands:

First, add the repository line to /etc/apt/sources.list

sudo tee -a /etc/apt/sources.list <<< "deb http://httpredir.debian.org/debian stretch-backports main contrib non-free"

Then update the APT database:

sudo apt-get update

Finally, install the packages:

sudo apt-get install --target-release stretch-backports linux-image-amd64 xserver-xorg-video-intel libegl1-mesa libgl1-mesa-glx libgl1-mesa-dri

This will generate a new GRUB menu entry for the backported kernel, the old kernel can still be selected from GRUB in case there are any problems.

New Intel graphics cards now require non-free firmware for full functionality. [1]

To install this firmware, use:

sudo apt-get install --target-release stretch-backports firmware-misc-nonfree

[1] Boo! Hiss! Boycott Intel! etc

Re: New Intel graphics cards & BunsenLabs

It boggles my mind how quickly 3rd party drivers can be written for proprietary hardware. I mean maybe it's just me, but reverse engineering a CPU chip and writing code to work with it, doesn't seem like something one does on the weekend after painting the fence...

That's what the nouveau developers do and they are indeed amazing smile

Fortunately, Intel do actually offer open source drivers:

The performance is crap compared to the proprietary versions but I suppose you get what you pay for...

Speaking of which...what's Intel's motivation for actually offering ANY OSS drivers for their goodies?

For users of Intel Broadwell and Skylake machines, the standard BunsenLabs kernel & video drivers offer limited support and poor performance.

Skylake

“There are literally over 600 million PCs out there that are over four years old,” says Moorhead. “It’s not that people aren’t using their PCs, they’re just using them less because they’re spreading their computing across phones, tablets, and watches.” In other words, the number of people to whom Intel’s gaudier comparisons apply is nearly twice the population of the United States. If you’re one of them, you may feel a bit like Rip Van Acer.

“The right comparison is to look at what those 600 million people are using,” Moorhead continues, citing the bulk and dilapidated batteries of those computational dinosaurs. “What they’re looking at now is for $499 to $699 they can get a very thin PC, with touch, more than likely seven to eight hours of battery life, weigh maybe 40 percent less. It will probably be able to rotate back, if you want to use it as a tablet.” Throw in features like Intel’s RealSense camera, which obviates the need for a system password by logging you in based only on your face, and the convenience factor of fewer cables, and you’ve got a strong case finally to upgrade.

So no, it’s not a surprise that Skylake is significantly better than the Core processors of 2010. What might catch you off-guard, though, is just how much more PCs can do overall.

@ostrolek: I do not understand.

What is the point you are trying to make?

Please explain clearly.

I wasn't making a point, just some discussion I found about/why skylake is here.
