Public bug reported:

https://askubuntu.com/questions/1514988/backlight-brightness-not-
working-in-ubuntu-23-10-24-04-on-dell-7700-aio

Ubuntu 23.10/24.04
Dell Inspiron 7700 AIO
6.5.0-35-generic/6.8.0-31-generic
X11

lsb_release -rd
No LSB modules are available.
Description: Ubuntu 24.04 LTS
Release: 24.04

dell_uart_backlight isn't in the 24.04 distribution, so Dell AIO display
backlights can't be adjusted. (dell_uart_backlight is in the 23.10
distribution, but backlight control doesn't work properly there either).

** Affects: linux (Ubuntu)
Importance: Undecided
Status: New
