Cannot alter brightness

Hi all,

I am having no luck at all in altering my display’s brightness settings. Simply put it’s been at maximum brightness since I’ve purchased it. This included upgrading the linux kernel through versions 5.11->5.13, and installing Linux Mint to the EDGE version to try rectifying the issue also.
