[Bug 743352] Re: LCD backlight doesn't respond to brightness control keys
Mike, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please provide the information following https://wiki.ubuntu.com/Kernel/Debugging/Backlight#Report_Minimum_Requirements ? As well, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux replace-with-bug-number Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag: needs-upstream-testing This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text: needs-upstream-testing If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Please let us know your results.

[Bug 743352] Re: LCD backlight doesn't respond to brightness control keys
I had the following problems (mbp6,2 + ubuntu 11.04): no backlight control no notifier-popup which usually shows that pommed is running/working Then I noticed that (the standard) nvidia_bl was not loaded. I loaded it with sudo modprobe nvidia_nl. Now the pop-up (on the upper righthand side of the screen) 'worked' again, but no change in brightness. I stopped pommed (sudo service pommed stop) and ran it manually with debug mode which shows that it adjusts the level from 0 to 2047 when hitting F1/F2 (or Fn-F1/Fn-F2 if you have fn-mode set to 2 in /etc/pommed.conf). similar, pommed -f showed it was happy with what it found (no backlight complaints). I reverted to mbp_nvidia_bl as a test and this worked: uninstall the nvidia_bl in 'synaptic package manager'. go to the repository in the 'settings' menu there and add the old maverick repository for mactel: click on add in the 'other software' tab and fill in 'deb http://ppa.launchpad.net/mactel-support/ppa/ubuntu maverick main' back in the main window of the synaptic package manager you 'reload' and install the mbp_nvidia_bl After a reboot, you first have to check whether mbp_nvidia_bl is loaded. (otherwise do 'sudo modprobe mbp_nvidia_bl') My /etc/X11/xorg.conf does not contain the extra option (commented out): #OptionRegistryDwords EnableBrightnessControl=1 I don't have a '_bl' anymore in the blacklists: 'grep bl /etc/modprobe.d/*' gives nothing.

@derp herp - make sure you don't have the nvidia_bl driver installed - instead I think you just need the mbp_nvidia_bl which comes with the standard kernel - if you have both, then the nvidia_bl conflicts and stops the mbp_nvidia_bl working correctly - uninstall nvidia_bl and then reboot and see if it works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/743352 Title: LCD backlight doesn't respond to brightness control keys To manage notifications about this bug go to: https://bugs.launchpad.net/mactel-support/+bug/743352/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 743352] Re: LCD backlight doesn't respond to brightness control keys
With respect to the No such device error, please note that the upstream 2.6.38 version of mbp_nvidia_bl does not support more recent machines such as the MBP6,2. An updated package has always been available in the Mactel PPA for maverick. I didn't upload a natty package yet, because the driver has been renamed to apple_bl (and changed) in upstream 2.6.39, and I think it might be better to backport the newer upsteam driver for natty. However, new issues with the 8th generation might arise because the new version doesn't contain an explicit model list anymore. Please use the maverick version for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/743352 Title: LCD backlight doesn't respond to brightness control keys -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 743352] Re: LCD backlight doesn't respond to brightness control keys
I suggest finding a temporary setup where the backlight control works, in which the nvidia driver is not installed, and then looking at lsmod | grep _bl or the contents of /sys/class/backlight/ which should hint at the module name that controls it. We can't blame the nvidia driver if the backlight has never worked under any Linux on the machine (though that appears to be the problem on my MBA 3,1). Also, you need to exclude the possibility that maybe your Macbook Pro hardware is still too new to be fully recognized by the 2.6.38 kernel in natty. So if you can't find a test setup above in which the backlight control ever works, please try temporarily installing the latest mainline kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.39-rc4-natty/ (linux-image-*.deb) I notice there have been a couple of commits to the apple_bl (formerly mbp_nvidia_bl) module in those recent kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/743352 Title: LCD backlight doesn't respond to brightness control keys -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Update: Machines up to MacBookAir 2,1 and MacBook Pro 5,5 are supported by maverick's default mbp_nvidia_bl.

[Bug 743352] Re: LCD backlight doesn't respond to brightness control keys
With the Macbook Air, you can take X out of the equation and reproduce the issue directly with the kernel by echoing various values into /sys/class/backlight/mbp_backlight/brightness With the Nvidia driver active, doing so does nothing just like the brightness keys on the keyboard. Removing the Nvidia driver and rebooting (nomodeset) into the standard vesa xorg setup, both the brightness keys and writing values into the kernel (as above) work again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/743352 Title: LCD backlight doesn't respond to brightness control keys -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It is very similar. And I'll have to double-check, but I think my notifications stopped working too.
