I dig into it and found that problem somewhere in ACPI code. 1. It does not proper export some functions and FreeBSD ACPI + xfce4-power-manager cant detect support this feature. I hack kernel: Index: /usr/src/sys/dev/acpica/acpi_video.c =================================================================== --- /usr/src/sys/dev/acpica/acpi_video.c (revision 350398) +++ /usr/src/sys/dev/acpica/acpi_video.c (working copy) @@ -1053,8 +1053,12 @@ dcs = 0; status = acpi_GetInteger(handle, "_DCS", &dcs); if (ACPI_FAILURE(status)) - printf("can't evaluate %s._DCS - %s\n", - acpi_name(handle), AcpiFormatException(status)); + status = acpi_GetInteger(handle, "_STA", &dcs); + if (ACPI_FAILURE(status)) { + /* Assume that device OK by default. */ + dcs = (DCS_EXISTS | DCS_ACTIVE | DCS_READY | + DCS_FUNCTIONAL | DCS_ATTACHED); + } return (dcs); } and now acpi/xfce4-power-manager show that feature supported but it does not work. (later I can move this hack into ACPI ASL code that load into bios, but it harder to maintain) 2. I dig more depper and decompile acpi code via isl. There is a mess. I found that function that set backlight level check some mem/register value before write new backlight value. I fail to found place where this value changed. I try rewrite code to remove this check and recompile ACPI and load new version witout this check on FreeBSD boot, it loaded but backlight still not work. Also I set in loader.conf: hw.acpi.osname="Windows 2015" # Some systems' ASL may have problems because they look for names of Microsoft operating systems. because there is at least 4 different places in decompiled ACPI where OS version and name checked - not help with blackligth, but as I see this unblock some features/devices. Also i2c touchpad dont work. https://reviews.freebsd.org/D16698 not help. For speakers probably wrong snddev set.
