Re: [ddccontrol-users] nvidia geforce go 6200 tc / general laptop support

[Oleg I. V. <ol...@cs...>]

Hi,

  this is slightly off-topic. :) You should write kernel module to call
ACPI stuff, so start reading ACPI related kernel sources. This is pretty
easy in fact. There are already number of modules for ASUS, IBM, etc.
laptops, which could be used as a good sample. I've not checked acpi for
sometime already, but it's possible that it has support for SONY laptops
already.

Regards,
Oleg.
