There's a `hw.acpi.video.lcd0.brigthness' sysctl, which i can modify, but no change actual brightness can be observed: # sysctl hw.acpi.video.lcd0.brigthness=3D1 hw.acpi.video.lcd0.brightness: 20 -> 1 # sysctl hw.acpi.video.lcd0.brigthness=3D100 hw.acpi.video.lcd0.brightness: 1 -> 100=20 Nor can the 'hw.acpi.video.lcd0.active=3D0' be changed by using=20 # sysctl hw.acpi.video.lcd0.active=3D1 hw.acpi.video.lcd0.active: 0 -> 0 (acpi_video.ko module was loaded while testing this, I made sure of that)=20 After none of this worked I loaded the acpi_call module. A lot of the comma= nds I threw at that had no effect or returned 'Unknown object type '0'=20 (including these ones:) #acpi_call -p '\_SB-PCI0-GFX0.DD02._BCM' -i 4 #acpi_call -p '\VBRU' '(Brightness Up)' #acpi_call -p \VBRD'=20 #acpi_call -p '\-SB.PCI0.GFX0.DD02._BQC' 0 #acpi_call -p '\-SB.PCI0.GFX0.DD02._BQC'=20 #acpi_call -p '\-SB.PCI0.GFX0.DD02._BCM' #acpi_call -p '\-SB.PCI0.GFX0.DD02._BCL' #acpi_call -p '\-SB.PCI0.GFX0.DD02._BCL' 10 #acpi_call -p '\-SB.PCI0.GFX0.DD02._BCL' 4 i3 window manager on Xorg CPU: Intel(R) Celeron(R) CPU 1007U @ 1.50GHz (1496.64-M) My make.conf file has nothing specified but: PACKAGES=3D/usr/ports/packages PS: fn+f5 and fn+f6 cannot be used to affect the brightness either and do n= ot change the value for =E2=80=9C hw.acpi.video.lcd0.brigthness=E2=80=9D eithe= r.=20 I came across more people experiencing the same issue as me while on my que= st to find a solution on the Internet. --=20 You are receiving this mail because: You are the assignee for the bug.=
