Hello, As Frank Groeneveld suggested here, I tried to disable acpivideo in the kernel, and it worked.
Thanks a lot to Frank :) ----- Original Message ----- From: "regis etourmy" <[email protected]> To: [email protected] Cc: "regis etourmy" <[email protected]> Sent: Sunday, 4 June, 2017 5:33:22 PM Subject: only two brightness values available (0% and 100%) with wsconsctl display.brightness on my EliteBook 820 G2 >Synopsis: only two brightness values available (0% and 100%) with >wsconsctl display.brightness on my EliteBook 820 G2 >Category: system amd64 >Environment: System : OpenBSD 6.1 Details : OpenBSD 6.1-current (GENERIC.MP) #0: Thu May 25 23:05:54 CEST 2017 [email protected]:/sys/arch/amd64/compile/GENERIC.MP Architecture: OpenBSD.amd64 Machine : amd64 >Description: I can set brightness only to two values with wsconsctl display.brightness=value If I choose 0, I get a low brightness, suitable for the night. If I choose any number between 1 and 100, I get the same full brightness, suitable for the outside daylight. There is a third value I get at boot time, which is between low and full. wsconsctl shows a value of 100%, but the real brightness is not full. If I ever change the value of display.brightness, I can never go back to this initial medium value. >How-To-Repeat: >Fix:
