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.

Bash alternative

Add setleds -D +num to ~/.bash_profile

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.
