Function keys don't work

If your F<num> keys do not work, this is probably because the kernel driver for the keyboard has defaulted to using the media keys and requiring you to use the Fn key to get to the F<num> keys. To change this behaviour, you have to change a driver setting. Do the following as root:

echo 2 > /sys/module/hid/parameters/pb_fnmode

If it tells you that the file doesn't exist, you probably have a newer kernel and will have to do the following instead:

echo 2 > /sys/module/hid_apple/parameters/fnmode

Place whichever command worked for you in /etc/rc.local to make the setting permanent.

< and > have changed place with § and ½

If the < and > are switched with the § and ½ keys, do the following:

setxkbmap -option apple:badmap

Place that in ~/.bash_profile, or if you use KDE:

Go to the "Control Center" -> "Regional & Accessibility" -> "Keyboard Layout" and press the "Xkb Options" tab. Scroll down and check the "apple" and "Swap keycodes of..." checkboxes. Click on "Apply".

If neither of these approaches seem to work, you can add these two lines to your ~/.Xmodmap file:

keycode  49 = less greater less greater bar brokenbar
keycode  94 = section degree section degree notsign notsign

if you use an canadian multilingual layout (where the "ù" and the "/" is switch) use this :

keycode  94 = slash backslash slash backslash bar brokenbar
keycode  49 = ugrave Ugrave ugrave Ugrave notsign notsign

Then run xmodmap ~/.Xmodmap.

Keysym mapping

To map the appropriate functions to your "media" keys place the following in ~/.Xmodmap:

keycode 160 = XF86AudioMute
keycode 176 = XF86AudioRaiseVolume
keycode 174 = XF86AudioLowerVolume

keycode 144 = XF86AudioPrev
keycode 162 = XF86AudioPlay
keycode 153 = XF86AudioNext

keycode 101 = XF86MonBrightnessDown
keycode 212 = XF86MonBrightnessUp

keycode 204 = XF86Eject

and run xmodmap ~/.Xmodmap. For more information about these mappings see Extra Keyboard Keys in Xorg. and mac hard drive recovery
