    I have a Macbook Pro connected to a Dell display via a Mini-Displayport to display port cable. I was previously able to control the brightness of the laptop display from my old keyboard from a Mac G4. One day, possibly when I installed a minor System update, I could no longer control the brightness. I was increasing the brightness by pressing F15 and decreasing the brightness by pressing F14. I bought a new Apple wired keyboard with dedicated brightness control buttons on F1 and F2, but I assume these only work with the Apple Cinema Displays. I also tried the old F14 and F15 keys, but those did not work either. In additon, I cannot find any way to add these commands in the keyboard shortcut menu. Does anyone know if this is still possible with the most updated version of OS X (10.6.7)?

    The brightness buttons (F1 & F2) on my MBP only control the brightness of the internal monitor - not the external. This is true using both the built in and an external BT keyboard. Also, if I go to preferences->displays the display setup on the external does not have the brightness slider that exists on the same window on the laptop display.

    I am not interested in changing the brightness of the external monitor. The only way to do that is through its own OSD. I used to be able to change the brightness of the laptop monitor when it is connected to the external monitor, but I no longer have this functionality.

    Oops, misread your post. Works for me with 10.6.7. Can you still adjust your brightness from the laptop's keyboard?

    One thing to check is if you have alternate function keys turned on. Go to preferences->keyboard and see if the "Use all F1, F2..." checkbox is checked.

    The F1 and F2 brightness controls on the laptop work fine all the time, and I tried it with both with the check box checked and unchecked.

    So what are you trying to accomplish exactly?

    Unfortunately, no. Then again, I have not researched it any further.

    Have you tried going to system preferences>keyboard>keyboard shortcuts and adding/changing it there?

    I don't know if there's any chance of doing this with the keyboard. However, there are many handy menubar apps that have brightness sliders. Look around for one and see if it works.

    Thank you for the suggestion. I just found one online "Brightness". I haven't tried it yet though.

    The brightness keys on the external keyboard will only work if you have the built-in monitor configured as the main monitor -- i.e., the menu bar and dock have to be on it.

    I think this must be a bug. Third-party software fixes might exist, I don't know.
