Thanks for your reply Matt, I don't know how to use BCL, but I tried: #acpi_call -p '\BCL' -i 8 Unknown object type '-1515870811' acpi_video doesn't work for me, it doesn't affect the backlight even though the value of brightness changes: #kldload acpi_video #sysctl hw.acpi.video.lcd0.active=1 hw.acpi.video.lcd0.active: 0 -> 0 #sysctl hw.acpi.video.lcd0.brightness=30 hw.acpi.video.lcd0.brightness: 70 -> 30 Digging through acpi dump is very tiring and I can't actually read it, I don't know what I am looking for and there are hundreds of strings to try using acpi_call for example, as far as i understand this should disable intel graphics card, but it does nothing: #acpi_call -p '\_SB.PCI0.PEG0.PEGP._OFF' 0 -- View this message in context: http://freebsd.1045724.n5.nabble.com/Lenovo-Y570-backlight-tp5726207p5726726.html Sent from the freebsd-x11 mailing list archive at Nabble.com.
