'acpi_backlight=vendor' works like before. dmesg: DMI: Acer Aspire 5750G/JE50_HR, BIOS V1.14 09/07/2011 acer_wmi: Acer Laptop ACPI-WMI Extras acer_wmi: Function bitmap for Communication Button: 0x1 input: Acer WMI hotkeys as /devices/virtual/input/input7 acer_wmi: Get 0x1 Device Status failed: 0xe2 - 0x0 When 'acpi_backlight=vendor' option is not present there is an additional message: acer_wmi: Brightness must be controlled by generic video driver And backlight control doesn't work. So I assume that patch works. :-) hm... that means my patch no works. If my patch works, means you don't need add 'acpi_backlight=vendor' for enable brightness control, acer-wmi will do the job.

Pressing these buttons change brightness only in X (KDE) environment, they don't work in terminal. Although they work in X, unhandled events are still logged. I think this is related to acpid and I need to write some script to handle these evenets, so it probably has nothing to do with this bug. :-) -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Keep Your Developer Skills Current with LearnDevNow!

Backlight control works well with `acpi_backlight=vendor`. I can use keys, /sys/class/backlight/intel_backlight/ interface and KDE backlight controls. Yes, this is another workaround to control brightness through i915 drm driver. When using keys I get unhandled event messages, they work only in X environment. If you need more information or some tests I can provide them. :-) I thought the keys means the Fn+left/right (brightness function key).

I already pass this situation to Acer PM face to face, he said will pass to BIOS team for _BCM doesn't work on many Acer machines. But, I didn't get further response from Acer. Currently, only 2 work around is use acpi_osi=Linux or acpi_backlight=vendor, the i915 brightness control works. I have no idea how to fix this problem because we confirm acer-wmi already write the brightness value to EC regitser, but we have no way to know the EC firmware is really change brightness. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Keep Your Developer Skills Current with LearnDevNow!

I would like to confirm, on Windows 7 it works without problem. Thank you! Read this: http://msdn.microsoft.com/en-us/windows/hardware/gg487382.aspx I thought brightness control key works on Windows 7 because it have WDDM video driver, but Linux didn't support WDDM. Per the above spec, windows driver will try 2 ways to modify brightness: + WDDM video driver + if no WDDM video driver, then will follow ACPI standard.

dmesg after echo * /sys/class/backlight/acpi_video0/brightness
echo 2 /sys/class/backlight/acpi_video0/brightness and
echo 9 /sys/class/backlight/acpi_video0/brightness
don't work.
Please find dmesg after these commands in the attached file.
Thank you!
Per your DSDT, in _BCM method, it write a value to the BRTS register in EC, I
believe this register handle brightness level:
Method (_BCM, 1, NotSerialized)
{
Divide (Arg0, 0x0A, Local0, Local1)
Decrement (Local1)
Store (Local1, ^^^LPCB.EC0.BRTS)
}
But, look like the EC firmware didn't change brightness when BRTS modified,
that's not make sense because it must be works on Windows 7. Your dmesg on
comment #14 confirm we are running the same logic path with Windows 7.
Next step is: we need to make sure the _BCM store value to BRTS is success, we
need monitor the EC's memory block.
I will find a good way for you to monitor it, might need EC expert's help.

Found the brightness control by this machine is follow standard acpi video
interface:
Method (_Q11, 0, NotSerialized) /* brightness
decrease */
{
...
If (LGreaterEqual (OSYS, 0x07D6)) /* Vista or
Windows 7 */
{
If (LEqual (OBV, 0xFF))
{
Notify (^^^PEG0.PEGP.DD01, 0x87)
}
Else
{
Notify (^^^GFX0.DD03, 0x87) /*
ACPI_VIDEO_NOTIFY_DEC_BRIGHTNESS 0x87 */
}
}
Method (_BCM, 1, NotSerialized)
{
Divide (Arg0, 0x0A, Local0, Local1)
Decrement (Local1)
Store (Local1, ^^^LPCB.EC0.BRTS)
}
This issue should not related to acer-wmi driver, even acer-wmi driver support
this machine, it cann't help anything for brightness control on this machine.
Did brightness control works before 2.6.39 kernel?
Could you please help to attached dmesg on this bugzilla?
Did you see and error message when you press Fn key to increase/decrease
brightness?
