which package or repo should I choose for ubuntu 20.04?

[yurenchen000]

I use ubuntu20.04, i7-10710U.

Before I add intel apt repo (https://repositories.intel.com/graphics/ubuntu)
from here (https://dgpu-docs.intel.com/installation-guides/ubuntu/ubuntu-focal.html)
I noticed some packages already exist in ubuntu origial repo:

$ apt show  intel-opencl-icd  intel-level-zero-gpu  level-zero  \
  intel-media-va-driver-non-free  intel-media-va-driver  libmfx1 | grep -E '^$|Package:|Version:|Sources:'

Package: intel-opencl-icd
Version: 20.13.16352-1
APT-Sources: http://mirrors.ustc.edu.cn/ubuntu focal/universe amd64 Packages

Package: intel-media-va-driver-non-free
Version: 20.1.1+ds1-1build1
APT-Sources: http://mirrors.ustc.edu.cn/ubuntu focal/multiverse amd64 Packages

Package: intel-media-va-driver
Version: 20.1.1+dfsg1-1
APT-Sources: http://mirrors.ustc.edu.cn/ubuntu focal/universe amd64 Packages

Package: libmfx1
Version: 20.1.0-0ubuntu1
APT-Sources: http://mirrors.ustc.edu.cn/ubuntu focal/universe amd64 Packages

those packages:

• intel repo
  • intel-media-va-driver-non-free
• ubuntu repo
  • intel-media-va-driver-non-free
  • intel-media-va-driver

I wonder which package should I choose (and how to check they works well)?

thank you.

Hi @yurenchen000, We recommend using the repo provided by intel for getting the latest packages.

Ubuntu also includes Intel drivers, but currently Ubuntu kernels miss full support for Intel discrete GPUs, and you need user-space drivers that match the kernel driver (they may use APIs that are not yet in upstream kernel, or differ from it).
