Created attachment 140098 xorg log
Archlinux xorg-server 1.20.0-6 xorg-xrandr 1.5.0-1 linux 4.16.13-2
With latest xorg 1.20, xrandr is not able to switch off the eDP-1 monitor after running "xrandr --verbose --output eDP-1 --off --output HDMI-1 --auto --primary" The monitor is correctly disabled, but the backlight will stay on. To completely switch off monitor a manual "xset dpms force off" is required.
If I downgrade to xorg 1.19.6 xrandr starts working correctly.
