This is still the same in a new install of Quantal (and IIRC it also was the same in Precise.

They worked fine, but I decided to try the nvidia-current (which I had used before with the previous install) and used Jockey to switch. This made Jockey install a new xorg.conf without the EnableBrightnessControl option. On reboot the keyboard brightness keys did therefore not work, I had to add the option to xorg.conf again and restart X. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/726692 Title: Screen backlight adjustment stopped working on MacBook Pro 5,4 and other hardware -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This workaround (with EnableBrightnessControl=1) does not work anymore with nVidia driver 270.41.06 (in 11.04). I heard about a possible solution: just add acpi_osi=Linux to kernel options (in GRUB config or manually on boot). So far I have not tested it.

[Bug 726692] Re: Screen backlight adjustment stopped working on MacBook Pro 5, 4 and other hardware
Sorry, my previous comment #10 was incorrect. What worked again after the reinstall was just the notification bubble, but it did not actually change the brightness. I had to add the EnableBrightnessControl option again, to the new xorg.conf that was created during installation.

There is a very similar bug here: #743352. However with bug #743352 the notification bubble appears to work and even /sys/class/backlight/mbp_backlight/* seems to function, but without correctly affecting the backlight.

Maybe this is an -nvidia bug, but if so there's not much we can do about it at the distro level. So I think this would be better to be reviewed by the g-p-m guys first. If it does turn out to be something to do with -nvidia particularly, it should be reported upstream - see http://www.nvnews.net/vbulletin/showthread.php?t=46678 ** Package changed: nvidia-graphics-drivers (Ubuntu) = gnome-power- manager (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/726692 Title: Screen backlight adjustment stopped working on MacBook Pro 5,4 and other hardware -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
