Alder Lake graphics driver in Ubuntu 20.04

ke flag

How can I get Alder Lake graphics drivers? I'm running 20.04 with the HWE-edge kernel (5.13), but I'm not able to use the igpu for hardware acceleration.

$ sudo lshw -c display
  *-display UNCLAIMED

With other new unsupported hardware (like a 2.5GBE) I've been able to download drivers from the manufacturer's website. Does nothing like this exist for intel?

Can you give an example of how you are trying to use hardware acceleration and how you know that it's not working? Are you using Ubuntu Desktop or any desktop environment? If your only graphics adapter is the iGPU and you are running a desktop environment, then it's working.

I'm running ubuntu server, and I'd like to use the iGPU for plex hw transcoding. The igpu isn't detected, and like other hw without drivers, it is shown as UNCLAIMED with the lshw command.

Eventually, the HWE-edge kernel was updated to 5.15 and included the intel drivers. You can see that now the i915 driver is shown with sudo lshw -c display.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
