Software Environment:
note: I am using UNPATCHED kernel sources directly from kernel.org, not patched
sources from gentoo's portage tree.
gcc version 3.3.5 (Gentoo Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1)
Problem Description:
Previous to my 2.6.11.6 upgrade I was running 2.6.9. With all unpatched 2.6
kernel versions up to and including 2.6.9, I could turn the lcd backlight off by
running "echo lcd_out:0 > /proc/acpi/toshiba/video" as root. I upgraded directly
from 2.6.9 to 2.6.11.6. With the upgrade I am no longer able to turn the lcd
backlight off. There is no effect after running "echo lcd_out:0 >
/proc/acpi/toshiba/video" and the /proc/acpi/toshiba/video lcd_out option
remains unchanged as 1. I recompiled the 2.6.11.6 kernel with the new option
CONFIG_BACKLIGHT_LCD_SUPPORT=y. Enabling this option did not allow the command
(echo lcd_out:0 > /proc/acpi/toshiba/video) to turn the lcd backlight off, or
change the lcd_out option to 0. However, I do get the following entry in my
kernel logs after running the command while running 2.6.11.6, "[kernel] video
bus notify". Previous to the upgrade, there was no entry in my kernel logs after
running the command.
Steps to reproduce:
build 2.6.11.6 with
CONFIG_TOSHIBA=y
CONFIG_ACPI=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
# CONFIG_ACPI_SLEEP is not set
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_VIDEO=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_IBM is not set
CONFIG_ACPI_TOSHIBA=y
CONFIG_ACPI_BLACKLIST_YEAR=0
# CONFIG_ACPI_DEBUG is not set
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y
# CONFIG_X86_PM_TIMER is not set
# CONFIG_ACPI_CONTAINER is not set
note: enabling the CONFIG_BACKLIGHT_LCD_SUPPORT option does not change anything.
and run, echo lcd_out:0 > /proc/acpi/toshiba/video

I tested 2.6.12-rc2 with the same results. I get the entry "[kernel]
video bus notify" in the kernel log
and the backlight does not turn off.

I don't think this made it to the list. sorry if this is a repeat.
I tested 2.6.10 and had the same problem. So it seems this version is
where the change/problem first appeared. All the tested kernels,
including the working and non-working, use the same Toshiba ACPI Extras
version, 0.18. I only guess that the new entry (after using the command
that previously turned the lcd backlight off) in the non-working
2.6.11->2.6.12-rc2 kernel logs (video bus notify) is something to
investigate. I also enabled the CONFIG_ACPI_DEBUG option and retested
the kernels with no luck.

I have tried to test the patch listed below, however, my attempts to
pass arguments to the /sys/module/backlight files hasn't been
successful. Could anyone provide some info on the proper usage? I will
test to see if this works in my case. Perhaps this patch in some manner
changes things making the command that previously worked ineffective?

[PATCH] backlight: Add Backlight/LCD device basic support
From: Andrew Zabolotny
Here's a patch that adds basic support for controlling backlight lamps
and lcd panels. The drivers can be controlled via sysfs, which makes it
easy to use both from scripts and programs.

I am not aware of the proper way to test and see if this would allow me
to control the backlight in this case. Perhaps this patch makes the
command that previouly worked ineffective? I will test this if anyone
could shed some light on how to use it.
