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 ?
Best regards,
André
