Apple Keyboard
Some keyboard models that use the Apple keyboard driver may have swapped keys or missing functionality. This article describes how to change the settings for the keyboard so that it behaves as expected.
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 Fn+F6
twice or thrice. You might need to use a utility like numlockx.
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.
hid_apple module options
fnmode
- Mode of top-row keys- 0 - disabled
- 1 - normally media keys, switchable to function keys by holding Fn key (=auto on Apple keyboards)
- 2 - normally function keys, switchable to media keys by holding Fn key (=auto on non-Apple keyboards)
- 3 - auto (Default)
iso_layout
- Enable/disable hardcoded ISO layout of the keyboard. Possibly relevant for international keyboard layouts- 0 - not ISO (=auto on ANSI keyboards)
- 1 - ISO (=auto on ISO keyboards)
- -1 - auto (Default)
swap_opt_cmd
- Swap theOption
(Alt
) andCommand
(Flag
) keys- 0 - as silkscreened, Mac layout (Default)
- 1 - swapped, PC layout
swap_fn_leftctrl
- Swap theFn
andL_Control
keys- 0 - as silkscreened, Mac layout (Default)
- 1 - swapped, PC layout
Function keys do not 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 the behavior temporarily, append 2
to /sys/module/hid_apple/parameters/fnmode
.
# echo 2 >> /sys/module/hid_apple/parameters/fnmode
To make the change permanent, set the hid_apple
fnmode
option to 2:
/etc/modprobe.d/hid_apple.conf
options hid_apple fnmode=2
To apply the change to your initial ramdisk, in your mkinitcpio configuration (usually /etc/mkinitcpio.conf
), make sure you either have modconf
included in the HOOKS
variable or /etc/modprobe.d/hid_apple.conf
in the FILES
variable. You would then need to regenerate the initramfs.
Switching Cmd and Alt/AltGr
This will switch the left Alt
and Cmd
key as well as the right Alt
/AltGr
and Cmd
key.
Temporary and immediate solution:
# echo "1" > /sys/module/hid_apple/parameters/swap_opt_cmd
Permanent change, taking place at next reboot:
/etc/modprobe.d/hid_apple.conf
options hid_apple swap_opt_cmd=1
You then need to regenerate the initramfs.
Swap the function and left control keys
This will switch the Fn
and left Ctrl
keys.
Temporary and immediate solution:
# echo "1" > /sys/module/hid_apple/parameters/swap_fn_leftctrl
Permanent change, taking place at next reboot:
/etc/modprobe.d/hid_apple.conf
options hid_apple swap_fn_leftctrl=1
You then need to regenerate the initramfs.
PrintScreen and SysRq
Apple Keyboards have an F13
key instead of a PrintScreen
/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 PrintScreen
/SysRq
to F13
, as well as Scroll lock
to F14
and Pause
to F15
.
Alternatively, follow the Map scancodes to keycodes article to map the F13
scancode to the PrintScreen
/SysRq
keycode, where 458856 (0x070068) is the scancode of F13
, and sysrq
is the keycode of PrintScreen
/SysRq
.
Treating Apple keyboards like regular keyboards
Depending on the customisations you want to accomplish, there are two solutions available and some options that are in the kernel. You need to choose one of the other.
Use a patch to hid-apple
While the original hid-apple
module does not have options to further customize the keyboard, like swapping Fn
and left Ctrl
keys or having Alt
on the left side of Super
, there is a patched version adding this functionality to the module. To use it, install the hid-apple-patched-dkms-gitAUR package. This will install the patched hid-apple
and mask out the original one.
The package uses DKMS to automatically recompile the module during kernel upgrades. While the dkms will be pulled in by dependency. You still need to install an appropriate kernel header package manually. See the DKMS page for more info.
In addition to the patched kernel module, a configuration file is also provided by the package at /usr/lib/modprobe.d/hid_apple.conf
, which enables PC-like layout by default:
- Top-row keys are normally function keys, switchable to media keys by holding Fn key, as in #Function keys do not work.
- Four keys at the lower left corner act as
Ctrl
,Fn
,Super
,Alt
, in this order. - Two keys at the lower right corner act as
Alt
,Ctrl
, in this order. - If you have an
Ejectcd
key, it will act asDelete
key.
If you wish to change the default options, copy the configuration file to /etc/modprobe.d
and make desired changes:
# cp {/usr/lib,/etc}/modprobe.d/hid_apple.conf
The file under /etc/modprobe.d
will completely override the one with the same name under /usr/lib/modprobe.d
, and the content is NOT merged.
Alternatively, put additional options in a file with a different name if you want to keep default ones,
Please refer to the project README for the exact meaning of each configuration option and tweaking the configuration file to suit your needs. Learn more about modprobe.d
at Kernel module#Using files in /etc/modprobe.d/.
After installation, reboot for the change to take effect, or #Change the Behavior Without Reboot.
Troubleshooting configuration not picked up by the module
First, make sure the patched version is loaded, see what parameters are provided by the module:
$ ls /sys/module/hid_apple/parameters/
If you do not see new options like swap_fn_leftctrl
, ejectcd_as_delete
, etc., check your DKMS installation.
Then, check if configuration files are correctly included in the initramfs:
$ mkdir /tmp/initramfs $ cd /tmp/initramfs # lsinitcpio -x /boot/initramfs-linux.img
Check the presence and content of usr/lib/modprobe.d/hid_apple.conf
and any other relevant configuration files in etc/modprobe.d/
. If they are not there, you should check your /etc/mkinitcpio.conf
to include those. By default, there should be a modconf
hook that automatically include those files, if not, add it to the HOOKS array after autodetect
.
Alternatively, specify those files in FILES array explicitly:
FILES=(/usr/lib/modprobe.d/hid_apple.conf)
Finally, regenerate the initramfs and reboot.
Use un-apple-keyboard
If you do not need all of these customizations and you do not want to compile a new module manually or using dkms, there is an AUR package un-apple-keyboardAUR which does not rely on a new kernel module, but rather just to mappings. It enables the following features:
- The keyboard is considered as an ISO keyboard (e.g.
<
and>
located at the right of theLeft Shift
key are working like expected). - The function keys are disabled by default. You need to press the
Fn
key in combination to trigger them. By default, the behavior are thus keysF1
toF12
- The
Alt
andCmd
keys are swapped. F13
is mapped toSYSRQ
,F14
toScroll Lock
andF15
toPause
.
The first 3 aforementioned features are brought to you using the default linux kernel module hid-apple
.
The last one is provided by providing a mapping to keyfuzzAUR.
Change the Behavior Without Reboot
To reload the kernel module without reboot, run
# rmmod hid_apple && modprobe hid_apple
Magic Keyboard does not connect
If you have a magic keyboard that will not connect to the system through the built in tools, such as the Gnome 3 bluetooth menu in settings, install blueman and its dependencies and attempt to connect with it. If it still fails to connect, make sure you have bluetoothctl and hcitool installed.
Enable dvorak/dvp
By default xkb loads translation table (actually called xkb_symbols
) macintosh_vndr/us
for macintosh keyboard:
$ setxkbmap -print -verbose 10 | grep symbols
This translation table located in /usr/share/X11/xkb/symbols/macintosh_vndr/us
and do not contains dvorak/dvp layout. You can use default translation table from /usr/share/X11/xkb/symbols/us
and add command setxkbmap
in your .profile
for forced loading layout:
# mv /usr/share/X11/xkb/symbols/macintosh_vndr/us /usr/share/X11/xkb/symbols/macintosh_vndr/us.back # cp /usr/share/X11/xkb/symbols/us /usr/share/X11/xkb/symbols/macintosh_vndr/us $ echo "setxkbmap -v 10 -layout us -variant dvp" >> .xprofile
No input during root disk decryption
You may have to manually add the hid_apple
module to the mkinitcpio configuration:
MODULES=(hid_apple)
Or place the keyboard hook before autodetect so that all keyboard drivers are included:
HOOKS=(... keyboard autodetect ...)
Regenerate the initramfs after doing either of these.
