Subject: ACPI quirks - acpi_osi="!Windows 2006" required on FSC Amilo notebooks to enable brightness keys
Date: Fri, 08 Jan 2010 16:14:14 +0100 [thread overview]
Message-ID: <537531092@web.de> (raw)
The brightness control keys (Fn+F7 & Fn+F8) only work when adding this boot parameter.
They do not create any events for the OS but work even when in BIOS or GRUB, but not in Linux without said kernel parameter.
Userspace tools are able controlling brightness using standard methods regardless of any ACPI parameters, they only seem to affect the keys themselves.
Forum reports state that this is true for the whole Fujitsu (Simens) Amilo series, tested on Amilo Pi 2515.
