Description Matt White 2012-11-30 00:45:41 UTC
The notifications pop up but the brightness doesn't change. It is at 100% brightness all the time which makes working in low-light conditions impossible and drains the battery. When using the integrated graphics, the brightness works just fine, but I can't use an external monitor via the mini-DVI port unless I use the Nvidia chip (discrete graphics option in BIOS). This is an Optimus machine, but the BIOS gives the option to use Optimus, discrete or integrated graphics.

I have tried in /etc/default/grub: kernel parameters acpi_backlight=vendor thinkpad-acpi.brightness_enable=1.

I have tried /usr/share/X11/xorg.conf.d/10-brightness-control.conf: Option "RegistryDwords" "EnableBrightnessControl=1"

I have tried editing /sys/class/backlight/acpi_video0/brightness with tee

I have tried kernel 3.5.7 and 3.6.3

Nothing changes the brightness.

Comment 5 Zhang Rui 2013-01-09 06:46:40 UTC
does acpi_osi="!Windows 2012" help?
Comment 6 Matt White 2013-01-09 16:41:48 UTC
Doesn't seem to make any difference. Should I be trying that in conjunction with other parameters? I tried it with acpi_backlight=vendor and then with thinkpad-acpi.brightness_enable=1, but no changes. (And yes I did update-grub each time)
Comment 7 Aaron Lu 2013-03-14 07:48:23 UTC
Hi Matt,

ACPI video driver can't handle Add-in display adapter, as the Nvidia graphics card in this case. So backlight control through ACPI is not possible. Your only hope should be the graphics driver for nvidia card, but I'm that sure about that.

This is the relevant information on this in ACPI spec, appendix B.2:
Add-in display adapter: This is a graphics chip or board that can be added to or removed from the computer. Because the system BIOS cannot have specific knowledge of add-in boards, ACPI information is not available for add-in devices.

I'll close it as invalid.
