I'm running 18.04 LTS and would like to upgrade my i7 Intel HD Graphics Kaby Lake driver.

I found that in general the following sources should be used: https://01.org/linuxgraphics/downloads/2018q1-intel-graphics-stack-recipe

But: There is no guideline.

  • Which of those files presented do I have to download, and how to install them?
  • Only the kernel?
  • What about the Xserver?

    Please note that Intel has discontinued the "Intel graphics for Linux". There will be no further release after 2018q1 (which targets 17.04). Intel says that the update processes built into Fedora and Ubuntu are mature enough to no longer necessitate a separate update site. Although it sounds more like it is them who can't keep up. In any case 01.org can't be used to update 18.04 LTS. – rustyx Dec 8 '18 at 21:16

Sorry, but if you need to ask how to do that ... just don't. You are more than likely to hose your system. I see already 1 issue: the mesa version in your download is 18.0. Ubuntu 18 is on Mesa 18.1 so it is already a newer version than the one you will download. That might be a problem.

There is a FAR easier method for doing this: use the PPA for it (see this launchpad page). It was updated 5 hours ago so you might be in luck. You can add it with this command and it will add all the packages listed on the website; you will need the package xserver-xorg-video-intel.

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

From the description of this PPA:

This PPA provides updated X (2D) and mesa (3D) free graphics drivers for Radeon, Intel, and Nvidia hardware. Updates packages provide:

  • All packages are automatically built twice a day when there are upstream changes
  • Vulkan 1.1+ on recent Intel and Radeon GPU
  • OpenGL 4.5+ support and new OpenGL extensions: http://mesamatrix.net
  • OpenCL support with updated libclc
  • gallium-nine support installed by default.
  • VDPAU and VAAPI Gallium3D accelerated video drivers
  • OpenMAX IL Bellagio and XvMC only on zesty and older - disabled since artful due to not being broadly used
  • packages built against latest LLVM
  • Disabled Ubuntu MIR

If the features you mention are not in there yet you could ask about it on the Phoronix forums. Those are the people that will update the drivers for us.

  • That was probably the advise I needed, I could update the drivers successfully. – membersound Aug 16 '18 at 11:17

    @membersound good! :) You will get updates normally now too. So any new build will get offered for installation. – Rinzwind Aug 16 '18 at 11:49
  • I know this question seems like an stupid question, but... If I upgrade my installation with all those "new" drivers and I discover that they don't improve any in my system... How can I uninstall all of them and reinstall the "old" standard set of drivers? – Juan Dec 6 '18 at 1:25
  • @Juan ppa-purge ppa:oibaf/graphics-drivers to completely revert the oibaf ppa changes – rustyx Dec 8 '18 at 21:02
  • Thanks, rustyx!!! BTW: Is it absolutely necessary to getback to the default drivers if the final result is the same? – Juan Dec 13 '18 at 18:31
