Hi there, Same for me using Ubuntu 22.04.4 LTS with my Dell Inspiron 5400 AIO. Last kernel tested is linux-generic-hwe-22.04, so 6.5.0-41 at this time, i cant adjust brightness. The slider is no longer visible.
So for now i stick with 22.04 and 5.15 GA kernel. As everything is working well with this configuration.
