>Synopsis: setting brightness with wsconsctl has no effect
>Category: kernel
>Environment:
System : OpenBSD 6.8
Details : OpenBSD 6.8 (GENERIC.MP) #98: Sun Oct 4 18:13:26 MDT 2020
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
Version 6.7 and earlier supported setting screen brightness using
wsconsctl. This command has no effect on 6.8. Brightness remains at
maximum level of 100%.
>How-To-Repeat:
undefined# wsconsctl display.brightness
display.brightness=100.00%
undefined# wsconsctl display.brightness=50
display.brightness -> 46.66%
undefined# wsconsctl display.brightness
display.brightness=100.00%
>Fix:
not aware of any
