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?
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
.From the description of this PPA:
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.
