Graphic drivers reverted to Gallium 0.4 on llvmpipe after Intel Graphics Update Tool was used

Asked by Petar Trandev on 2017-09-26

I used the Intel Graphics Update to update the graphics driver but it reverted to Gallium 0.4 on llvmpipe (LLVM 4.0, 128 bits).
I don't know how to change the driver to the Intel one. My GPU is Intel HD Graphics 405 (Braswell).

It's not loading the driver and is why the hardware is "unclaimed"

If you run:

sudo modprobe i915

Does it load OK?

Running sudo modprobe i915 outputs:

modprobe: ERROR: could not insert 'i915': Required key not available

I looked it up and tried disabling secure boot with mokutil. The correct drivers were displayed after boot but I would really like to keep the secure boot enabled if possible.

Do you dual boot with Windows?

Petar Trandev (tajibor) said : #6

No I don't.

Then what does secure boot give you that you need?

Petar Trandev (tajibor) said : #8

Nothing really, I was paranoid I guess.
Thanks for the help :)
