[RESPONDED] Ubuntu 22 brightness keys not working

Looks like that come from a forum post vs the official guide. For 12th gen with Ubuntu 22.04, please open a terminal and paste as follows:

sudo gedit /etc/default/grub

then on the line with GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash”

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash module_blacklist=hid_sensor_hub"

Save the file. Close the text editor.

Back in a terminal:

sudo update-grub

Then reboot.
