Hi,
I've installed daedalus on a Laptop. ( trough devuan_daedalus_5.0.1_amd64_desktop.iso )
Sometime when I press fn + F5 I can lower my screen brightness, sometimes nothing happen (or the screen turn off completely the backlight )
I've installed brightnessctl
brightnessctl return:
Device 'platform::kbd_backlight' of class 'leds':
Current brightness: 1 (100%)
Max brightness: 1
brightnessctl -l
Available devices:
Device 'platform::kbd_backlight' of class 'leds':
Current brightness: 1 (100%)
Max brightness: 1
Device 'input0::scrolllock' of class 'leds':
Current brightness: 0 (0%)
Max brightness: 1
Device 'input0::capslock' of class 'leds':
Current brightness: 0 (0%)
Max brightness: 1
Device 'input0::numlock' of class 'leds':
Current brightness: 0 (0%)
Max brightness: 1
brightnessctl set 50% or brightnessctl set 0.5
Do not change the brightness but brightnessctl repport brightness at 0% O_o
Thanks.

I've did also xrandr -q and I get
xrandr: Failed to get size of gamma for output default.
So I suppose It's a problem with the drivers ?
Meanwhile even if it's the winter here, I'm working with sunglasses XD
