Subject: Controlling backlight on thinkpad x60
Date: Mon, 8 Sep 2008 17:10:58 +0200 [thread overview]
Message-ID: <20080908151058.GA1650@elf.ucw.cz> (raw)
Hi!
Some time ago, FN-Home/End just adjusted the brightness, and
/proc/acpi/ibm contained backlight control.
In 2.6.27-rc5, /proc/acpi/ibm does not contain backlight control and
/sys/class/backlight is empty...
(I do have CONFIG_ACPI_VIDEO disabled, it killed my machine last time
I enabled it, is it mandatory now?)
Pavel
