This Intel packaged driver is derived from the same sources as their upstream open-source driver stack, just that it's been built as Debian packages for Ubuntu 22.04 LTS and then the DKMS module on the kernel graphics driver side.

This packaged driver for Ubuntu 22.04 is akin to AMD's Radeon Software for Linux 'AMDGPU-Open' driver stack option for supported enterprise / Long-Term Support distributions. So long story short, it's much easier to get going now with Arc Graphics on Ubuntu 22.04 LTS that otherwise lacks out-of-the-box support for the DG2/Alchemist graphics processors. Intel has spun a packaged driver solution that deploys the updated Mesa driver stack and then backported the i915 kernel module to work as a DKMS module atop Ubuntu 22.04's 5.17 OEM kernel option. If as an Ubuntu Linux user you have been held off on purchasing one of the new Arc Graphics discrete graphics cards due to the prospects of having to upgrade your own kernel, Mesa, and linux-firmware packages, Intel has a solution for Ubuntu 22.04 LTS users in the form of a packaged driver.
