Hello,

As Frank Groeneveld suggested here, I tried to disable acpivideo in the kernel, and it worked.

Thanks a lot to Frank :)

>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.
