Hi!

I bought new Lenovo Legion 5 Pro 16" laptop and decided to install kubuntu 22.04. When i try to control screen brightness using corresponding fn-keys on keyboard or slider in battery applet the brightness is changing very strange. When i change from 0% to 10% the screen brightness is changed from lowest to highest. When control goes above 10% the brightness goes back to low. Further changing between 11% to 100% again goes from low to high.
