Brightness Controls Not Working

Asked by Sean Merrill

I am using a MacBook Pro 5.5 with Ubuntu 12.10. I cannot get the brightness controls to change the physical brightness of the screen. The buttons do activate the screen brightness bar but nothing happens to the actual brightness. I have tried the suggestion in 211457 but it didn't help. Here are the results of my diagnostic:

You also have a Natty source. Did you upgrade directly from Natty to Quantal?

Revision history for this message
Sean Merrill (sean-p-merrill) said : 		#2

I installed Quantal from scratch. The Natty source was based on a
suggestion for getting the brightness control to work from the Precise
installation page:

https://help.ubuntu.com/community/MacBookPro5-5/Precise

The other steps listed above that one did not work.

    LCD Brightness Control

The package nvidia-bl-dkms is not available for 12.04. Fortunately, the
following procedure works (taken from
http://www.voria.org/forum/viewtopic.php?f=3&t=1091):

If backlight control does not work for you, follow these instructions:

  * Edit the file '/etc/X11/xorg.conf' and add this line into the Device
    section:
      o

        Option "RegistryDwords" "EnableBrightnessControl=1"

  * Reboot and check if backlight control works. If so, you're done.
  * If not, edit the file '/etc/default/grub' and change the line:
      o

        GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to
        GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

  *

    Update grub with this command: sudo update-grub

  * Reboot and backlight control should work.
  *

    If it still doesn't work, try installing the nvidia-bl-dkms package
    from mactel-support for Natty (from
    https://launchpad.net/~mactel-support/+archive/ppa
    <https://launchpad.net/%7Emactel-support/+archive/ppa>), this was
    the only way for me to get the backlight control working on Precise.
    Results may vary as some people claim this driver does not work on
    Precise.

Try acpi_osi=

So the /etc/default/grub line : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

become like this

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="

Then update grub

sudo update-grub

and reboot.

Thanks

I changed the GRUB as you suggested but it is still not changing the
brightness of the screen.

Did you even read the link I gave...?

Did you add the PPA mentioned?

Hi Andrew,
The link you provided was the same steps I went through in which I added the natty source. I tried steps 3-6 under the LCD Backlight section but I don't have a xorg.conf file and didn't know how to properly format one to create from scratch. There are many examples but I didn't know which to emulate. If you have a link to a usable xorg.conf file, I'd be happy to try it out.

My apologies for the trouble. I reinstalled ubuntu 12.10 and the brightness works out of the box. I must have messed something up while trying things out.
