Re: [Bug 226894] Re: Backlight control does not work on MacBook Pro 3.1
MacBook Pro 5,4 requires nvidia_bl_dkms (NOT mbp_nvidia_bl_dkms) from the Karmic Mactel PPA. Come on it's not too late to slip this fix in to the main lucid release!

The Fn keys work but as the notification bubble brightness bar changes, the LCD backlight brightness does not change (it's fixed at the maximum level). I inserted the mbp_nvidia_bl kernel module and voila! I can echo N to /sys/class/backlight/mbp_backlight/brightness to now adjust it. However, the Fn keys have no effect. -- Backlight control does not work on MacBook Pro 3.1 https://bugs.launchpad.net/bugs/226894 You received this bug notification because you are a direct subscriber of the bug. -- Backlight control does not work on MacBook Pro 3.1 https://bugs.launchpad.net/bugs/226894 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 226894] Re: Backlight control does not work on MacBook Pro 3.1
I personally cannot test 3.1 anymore but I can tell you that 5.4 does not work out of the box as of Sunday night updates. By the way, no need to remove 3.1 from the bug summary...

The only other reason is that the kernel module is not autoloaded.

It is fixed upstream in HAL *and* in the Linux kernel.

A workaround for both broken components pertaining to the backlight is posted in the description.

Re: [Bug 226894] Re: Backlight control does not work on MacBook Pro 3.1
As far as I am aware, for MacBook Pro 3,1 and 4,1, the mbp_nvidia_bl module is what is needed to make the backlight usable. I have a 4,1, and with latest hal, my backlight control is broken when I have that module loaded. I will have a dig in the hal package to see what has been c hanged.

Re: [Bug 226894] Re: Backlight control does not work on MacBook Pro 3.1
Further reading of the fdi file for MacBook Pros, I see that machies that are MacBookPro3,1 or earlier will still not work with the new backlight functionality that I have working. The fdi file needs to be rewritten to only add custom backlight keys for those MacBook pro generations that need it, i.e ones that don't have an NVIDIA chip. -- Backlight control does not work on MacBook Pro 3.1 https://bugs.launchpad.net/bugs/226894 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

3.1 has NVidia.
