Just installed this weekend:
6.2.0-37-generic
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
i915 is the driver in use
This looks like the piece your 5.15 kernel would be missing:
Seems to be present in 6.1 forward?
So in your case, per that Intel article, it looks like you would want to do that additional 2.1.5 step if you stick with the old kernel (although the rest of the article after the quote I pasted expects you to have 5.19?):
Use of the standard upstream Ubuntu 23.04 kernel is the easiest install path.
The out-of-tree driver may be of interest for scenarios such as:
- GPU debugging
- Access to the latest Intel updates that have not been upstreamed yet
- Other constraints do not allow you to move your base OS or kernel forward.
NOTE: Use of Intel’s out-of-tree driver is not validated on top of the default kernel provided with Ubuntu 23.04. If you plan to use GPU debugging, you must use Ubuntu 22.04 LTS HWE and the out-of-tree kernel module.
If you would like to try the new drivers and GPU debugging in a virtual machine (VM) without modifying the default Ubuntu 23.04 experience, see Client Virtualized.
If you are looking to support the latest Intel client GPUs on Ubuntu 22.04 LTS, you can use the out-of-tree kernel module Intel provides or using the upstream 6.2 kernel. See Kernel Driver Types for more information. If you do not require GPU debugging, it is recommended that you install a 6.2 kernel from the Ubuntu Kernel PPA and do not install the out-of-tree driver package described below.
