Activating Numlock on Bootup

Console

Install the package systemd-numlockontty^AUR from the AUR.

Now you should enable the numLockOnTty.service daemon. Read Daemons for more details.

X.org

Various methods are available.

startx

Install the numlockx package and add it to the ~/.xinitrc file before exec:

#!/bin/sh
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)
#

numlockx &

exec window_manager

KDM

If you use KDM as a login manager, add:

numlockx on

to the /usr/share/config/kdm/Xsetup, or the /opt/kde/share/config/kdm/Xsetup for KDM3.

Note that this file will be overwritten on update without creating a .pacnew file. To prevent this, add the following line to /etc/pacman.conf file (omit the leading slash in the path):

NoUpgrade = usr/share/config/kdm/Xsetup

KDE4 Users

Go to System Settings, under the Hardware/Input Devices/Keyboard item you will find an option to select the behavior of NumLock.

Alternate Method

Alternatively, add the script the ~/.kde4/Autostart/numlockx containing:

#!/bin/sh
numlockx on

And make it executable:

$ chmod +x ~/.kde4/Autostart/numlockx

GDM

First make sure that you have numlockx (from extra) installed then add the following code to /etc/gdm/Init/Default:

if [ -x /usr/bin/numlockx ]; then
      /usr/bin/numlockx on
fi

GNOME

When not using the GDM login manager, numlockx can be added to GNOME's start-up applications.

Install numlockx from the official repositories. Then, add a start-up command to launch numlockx.

$ gnome-session-properties

The above command opens the Startup Applications Preferences applet. Click Add and enter the following:

Name:	Numlockx
Command:	/usr/bin/numlockx on
Comment:	Turns on numlock.

Note: This is not a system-wide change, repeat these steps for each user wishing to activate NumLock after logging in.

SLiM

In the file /etc/slim.conf find the line and uncomment it (remove the #):

#numlock             on

OpenBox

In the file ~/.config/openbox/autostart add the line:

numlockx &

And then save the file.
