I have installed Ubuntu MATE 22.04 and Kubuntu 23.04 on two Chromebooks with amd64 architecture.
The media keys are not working. I can change brightness from system settings, but the media keys are mapped to F1 - F10.
How to make the media keys work?Everything else works perfectly.
Note: The media keys work out of the box in GalliumOS, but it is based on Xubuntu 18.04, and is not being actively developed anymore. I want to use the latest LTS version of Ubuntu in my Chromebook.
