After "kldload acpi_video" devinfo -v shows the following (truncated): nexus0 acpi0 pcib0 pnpinfo _HID=PNP0A08 _UID=0 at handle=\_SB_.PCI0 pci0 hostb0 pnpinfo vendor=0x8086 device=0x0104 subvendor=0x17aa subdevice=0x21ed class=0x060000 at slot=0 function=0 vgapci0 pnpinfo vendor=0x8086 device=0x0116 subvendor=0x17aa subdevice=0x21ed class=0x030000 at slot=2 function=0 handle=\_SB_.PCI0.GFX0 agp0 drm0 drmn0 acpi_video0 Assuming the patch cannot help me, do you have an idea what I could check next? I can control the brightness with acpi_call -p '\VBRU' acpi_call -p '\VBRD' https://d2ux.org/owncloud/public.php?service=files&t=7022f90cea5e48da7fa65806c0d66091 Regards, MatthiasReceived on Tue Jul 09 2013 - 17:19:23 UTC
