drivers for Lenovo 3000 series?

[Andika Triwidada]

Hi all,

I have a Lenovo 3000 G430 [1] which seems to work ok except for
brightness control

but from [2]:
"... The ACPI and EC firmware are completely incompatible with
ThinkPads, and ibm-acpi/thinkpad-acpi will not support it. The Lenovo
3000 are not ThinkPads."

so, what do you suggest? create a new driver for Lenovo 3000 series?
Can I use thinkpad_acpi.c as a start or should I start from scratch?

Thanks
Andika Triwidada

Will you please check whether there exists the ACPI generic backlight
I/F under the /sys/class/backlight/acpi_video0/*? If exists, please
check whether the backlight can be controlled by using the sys ACPI I/f.
   for example: echo 5 > /sys/class/backlight/*/brightness
   (Of course you had better test it under the X environment. And you
should assure that the acpi video driver is loaded).

Will you please attach the output of acpidump?

Is this an Intel graphics machine? Is the i915 driver loaded?

please apply this patch
http://marc.info/?l=linux-kernel&m=123982845406021&w=2
on top of 2.6.30-rc1 and see if /sys/class/backlight/acpi_video0/ comes
back again.

If it doesn't help, please file a new bug report at
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
so that we can track this bug better.

thanks,
rui

[Zhang, Rui]

This is a duplicate of bug http://bugzilla.kernel.org/show_bug.cgi?id=13048
So, no need to create a new bug report.
