Subject: 2.6.25-rc1 regression - IBM ACPI backlight
Date: Thu, 14 Feb 2008 11:38:01 +0100	[thread overview]
Message-ID: <20080214103801.GB4366@ics.muni.cz> (raw)

Hello,

as of 2.6.25-rc1, there is no more /sys/class/backlight/acpi_video1 which
controlled LVDS backlight on Lenovo ThinkPad T61. There is still acpi_video0
which seems to have sane values but echo N > brightness has no effect at all.

thinkpad_acpi module reports that ACPI controlled backlight is present.
