Hello, On my laptop computer , the keys F11 and F12, adjusts the brightness of the screen. But on Debian-Stretch with trinity, these two keys do nothing. Before I could do that with "Configure your Desktop" and "Configure tdepowersave" with a scale from 0 to 100%. But now, it's gone. Any Idea to do that with Trinity or with F11 and F12 ?
