    [SOLVED] Brightness Control Under Intrepid MacBook Pro Penryn

    Under Intrepid Release Candidate with Pommed installed all of my hotkeys work except for brightness. The keys do nothing. Furthermore, xbacklight claims that I don't have any supported devices which is clearly untrue as gnome-power-manager manages to dim my screen when not on AC power. I would like finer grained control than that though preferably using my hotkeys as under Hardy. But getting xbacklight to work would be enough.

    I think there is a bug. A patch has been submitted and fixed packages are in the Mactel-Support PPA

    Thanks for your quick reply, but that isn't it, I don't think. I already had the mactel ppa in my sources and picked up the new version a few hours ago... also when connecting/disconnecting AC power the brightness change is almost instant so I don't think I'm suffering from the same problem as in that bug.

    OK, give me a sec... I have a MacBookPro4,1 that I can test the RC on...

    EDIT: Well, nothing works at all for me so apparently the functions are all dependent on extra packages, but I cannot install them right now. Sorry. Might wait for kosumi68 to respond. He can probably help.

    O.K. thanks anyway. Yes, I figured it would be you or he that would come up with something.

    1. pommed is not needed, deinstall it to avoid confusion.

    2. you need the mbp_nvidia_bl kernel module installed in /etc/modules.

    3. hal might interfere: remove your macbook model from /usr/share/hal/fdi/policy/10osvendor/10-macbookpro-utils.fdi.

    4. LCD backlight should work automatically via gnome-power-manager which uses xrandr (same as xbacklight). Use the mactel version of g-p-m.

    5. Keyboard backlight works through the hal-applesmc package.

    Hopefully these things does it for you
