That would be a question for our OEM/kernel teams. I don’t know about their backporting plans.
A quick check shows that:
- The required Mesa is only in Ubuntu 22.10.
- The required kernel is soon to be available in 22.04 (but not 22.10?).
Safe to say that official long term support should be available by Ubuntu 22.04.2 in February 2023.
If you had the hardware before then you could probably get it working by:
- Install Ubuntu 22.10 (graphics will be low resolution but should be usable).
- Add kernel 6.0 (mainline or Ubuntu OEM supported) to enable full graphics support.
