If /proc/acpi/video doesn't exist, you need to change your kernel config. Enable CONFIG_VIDEO_OUTPUT_CONTROL and CONFIG_ACPI_VIDEO
(In reply to comment #3) > If /proc/acpi/video doesn't exist, you need to change your kernel config. > Enable CONFIG_VIDEO_OUTPUT_CONTROL and CONFIG_ACPI_VIDEO > well NOW i feel foolish. closing this bug. i had CONFIG_VIDEO_OUTPUT_CONTROL enabled but not CONFIG_ACPI_VIDEO. menuconfig FAIL. how embarrassing. thank you so much!
