[Bug 12637] Re: LCD Brightness on Laptop Always Set Very Low at Boot

[Adriano Del Vigna]

About the remaining test, they gave no effect, not a change at all.

* ACPI boot parameter "acpi_apic_instance=2" (as pointed in boot messages)
* ACPI boot parameter "acpi_osi=Linux" (as pointed in boot messages)

I appended those parameters, each a time, at a /boot/grub/menu.lst
special entry for ACPI tests (exactly the same as the latest kernel, but
with the extra parameters).

By the way, while shuting down the laptop, the LCD dims too.
