[RESPONDED] Cannot get Fn+F7 and Fn+F8 o adjust brightness on Framework 13 Intel 12gen

The title says it all. After an entire day of googling and other problem solving attempts, I cannot get this to work. Strangely enough, all the other Fn functions work! AGH

Please, gurus, help me!

Edit: Sorry! Distro is Mint Xfce 21.2

Not sure which distribution you are using, so you will have to adapt this solution to your case:

Sorry! It’s Mint 21.2 Xfce

Welcome to the community!

While Mint is one of our community support distros and not one of the officially vetted ones like Ubuntu 22.04.3 (there are differences from Mint) or Fedora 39, we do have an older guide for Mint.

The secret sauce is to append the following to the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash section.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash module_blacklist=hid_sensor_hub"

Then run

sudo update-grub

Then reboot.

Note, with this in place, you merely press the keys - no use of the Fn button is used for this.

Victory! Thank you so much. I’m relatively new to linux and felt like a dork making a dedicated thread for this, but it worked!

Note: it does work with the “Fn” button. Fn+F7 for dim, Fn+F8 for increase. Figured I should report this.
