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 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
