Hello,
I applied the patch, trying to get brightness controls for my X121e.
But it looks like I need a different loader.conf setting.
hw.pci0.0.2.0.handle="\\\\_SB_.PCI0.PEG.VID"
doesn't work. In my ASl there is only one device providing DOD / DOS:
Scope (_SB.PCI0)
{
Device (GFX0)
{
Name (_ADR, 0x00020000) // _ADR: Address
Method (_DOS, 1, NotSerialized) // _DOS: Disable Output
Switching
{
Store (And (Arg0, 0x07), DSEN)
If (LEqual (And (Arg0, 0x03), Zero))
{
If (CondRefOf (HDOS))
{
HDOS ()
}
}
}
Method (_DOD, 0, NotSerialized) // _DOD: Display Output
Devices
{
If (CondRefOf (IDAB))
{
IDAB ()
}
Else
{
So this is the \_SB_.PCI0.GFX0 device. However, you should kldload acpi_video
and see if it already attaches to this device (devinfo -v can be helpful here
as it will show the ACPI handle of the parent of the acpi_video device). If
it does, then this patch can't help you.
Hi John,
thanks for this hint. 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'
