Numlock is on
You may find that the numlock is on. The symptoms are that only the physical keys 7,8,9,u,i,o,j,k,l and surrounding keys work and output numbers. To fix this hit
Alternatively, set the keycodes manually using xmodmap to avoid use Numlock:
keycode 90 = KP_0 KP_0 KP_0 KP_0 KP_0 KP_0 keycode 87 = KP_1 KP_1 KP_1 KP_1 KP_1 KP_1 keycode 88 = KP_2 KP_2 KP_2 KP_2 KP_2 KP_2 keycode 89 = KP_3 KP_3 KP_3 KP_3 KP_3 KP_3 keycode 83 = KP_4 KP_4 KP_4 KP_4 KP_4 KP_4 keycode 84 = KP_5 KP_5 KP_5 KP_5 KP_5 KP_5 keycode 85 = KP_6 KP_6 KP_6 KP_6 KP_6 KP_6 keycode 79 = KP_7 KP_7 KP_7 KP_7 KP_7 KP_7 keycode 80 = KP_8 KP_8 KP_8 KP_8 KP_8 KP_8 keycode 81 = KP_9 KP_9 KP_9 KP_9 KP_9 KP_9
Repeating keys on a wireless keyboard
Unpair the keyboard and then re-pair it. The trick is to hold down the power button throughout the entire pairing process.
Function keys do not work
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 the behavior temporarily, append
/sys/module/hid_apple/parameters/fnmode. To make the change permanent, set the
fnmode option to 2.
< and > have changed place with § and ½
If the < and > are switched with the § and ½ keys, set the xkb option
apple:badmap, for instance by running the following command in your graphical environment:
$ setxkbmap -option apple:badmap
Alternatively, set the keycodes manually using xmodmap:
keycode 49 = less greater less greater bar brokenbar keycode 94 = section degree section degree notsign notsign
If you use a 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
< and > have changed place with ^ and ° (or @ and #, or ` and ~)
With German layout, circumflex/degree symbol and </> are exchanged. With French layout, @/# are exchanged. With the US layout, `/~ and </> are exchanged.
PrintScreen and SysRq
Apple Keyboards have an
F13 key instead of a
SysRq key. This means that Alt+SysRq sequences do not work, and application actions associated with
PrintScreen (such as taking screenshots in many games that work under Wine) do not work. To fix this, you can add
setxkbmap -option "apple:alupckeys" to your
.xinitrc. This will map
F13, as well as
Scroll lock to
Alternatively, follow the Map scancodes to keycodes article to map the
F13 scancode to the
SysRq keycode, where 458856 (0x070068) is the scancode of
sysrq is the keycode of
Treating Apple keyboards like regular keyboards
If you want to use your Apple keyboard like a regular US-layout keyboard, with
Alt on the left side of
Meta, you can use the AUR package AUR. Currently it only works for the aluminium USB model. The package does the following things:
- Adds a
/etc/modprobe.d/hid_apple.conffile which enables the
F<num>keys by default, as in #Function keys do not work.
- Uses keyfuzz to remap
Scroll Lock, and
- Swaps the ordering of the
Command) keys to match all other keyboards, again using
/etc/modprobe.d/hid_apple.conf, as in #Swap the Alt key and Command key (Meta/Super).
- Applies these changes automatically when you plug in your keyboard, with a udev rule.
You will need to add
/etc/modprobe.d/hid_apple.conf to FILES in mkinitcpio.conf. Otherwise if you boot your computer with the Apple keyboard plugged in, the the
F<num> keys will not work by default.
Swap the Alt key and Command key (Meta/Super)
Swap the Fn key and Left Ctrl key
While the original
hid-apple module doesn't have an option to swap the fn and left control keys, there is a patch adding this functionality to the module. To install the patch, install the AUR[broken link: package not found] package.
