[[Geoff Streeter]] authored a paper, [https://www.dyalog.com/uploads/conference/dyalog10/presentations/P19_Streeter_Keyboards.pdf Supporting APL keyboards on Linux], which was presented at the [https://aplwiki.com/wiki/Dyalog_user_meeting#Dyalog_.2710 Dyalog '10] user meeting. In this paper, Geoff details how APL keyboards can be supported in [[wikipedia:X_Window_System|X11]] using <source lang=console inline>xkb</source>, the [https://www.x.org/wiki/XKB/ X Keyboard Extension].
Most Linux distributions released after mid-2012 have Dyalog keyboard support included with the distribution.

==== setxkbmap ====
 
The simplest way to set up an APL keyboard on Linux is with the following <source lang=console inline>setxkbmap</source> command. Enter the following in your terminal emulator of choice:
 
<source lang=console>
setxkbmap -layout us,apl -variant ,dyalog -option grp:switch
</source>
 
An explanation:
 
* <source lang=console inline>-layout us,apl</source> assigns <source lang=console inline>us</source> ([[wikipedia:American_English|U.S. English]]) to be the primary layout, whereas <source lang=console inline>apl</source> is secondary
 
* <source lang=console inline>-option grp:switch</source> assigns <kbd>Right Alt</kbd> to switch to the secondary <source lang=console inline>apl</source> layout when it is pressed, otherwise <source lang=console inline>us</source> is used
 
* <source lang=console inline>-variant ,dyalog</source> assigns the [[Dyalog APL]] variant to the <source lang=console inline>apl</source> layout which contains modifiations unique to the Dyalog language ('''Note the preceding comma''')
 
A full list of keys that can be used to switch layouts is included in <source lang=console inline>/usr/share/X11/xkb/rules/evdev.lst</source> under the <source lang=console inline>option</source> category.
 
'''Note:''' these changes are not permanent; the user will have to select one of a myriad of methods to run the command on startup. Alternatively, if they use one of the [[wikipedia:Desktop_environment|desktop environments]] listed below, they can follow those instructions.
 
==== GNOME ====
 
===== GUI =====
 
# Open the Activities menu; this is located in the top-left corner of a default GNOME 3 session (alternatively, use your <kbd>Super</kbd> key to open the Activities overlay):<br>[[File:Gnome-kbd-setup-1.png|frameless|GNOME Keyboard Step 1: Open Activities Menu]]
# Search for "startup." When the Startup Applications program is highlighted, press the <kbd>Enter</kbd> key to open it: <br>[[File:Gnome-kbd-setup-2.png|frameless|GNOME Keyboard Step 2: Search for Startup Applications]]
#Select the <kbd>Add</kbd> button on the right-hand side:<br>[[File:Gnome-kbd-setup-3.png|frameless|GNOME Keyboard Step 3: Click the <kbd>Add</kbd> button in Startup Applications window]]
#Provide a name, enter your <code>setxkbmap</code> command, and click <kbd>Add</kbd> when finished:<br>[[File:Gnome-kbd-setup-4.png|frameless|GNOME Keyboard Step 4: Enter the relevant information for your command]]
 
===== Terminal =====
 
# Navigate to <code>~/.config/autostart</code> and create a <code>.desktop</code> with any name that will help you remember its function.
# Add the following to the contents of your file, customizing to suit your needs:<source lang=ini>
[Desktop Entry]
Type=Application
Exec=setxkbmap -layout us,apl -variant ,dyalog -option grp:switch
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name[en_US]=apl-keyboard
Name=apl-keyboard
Comment[en_US]=
Comment=
</source>
 
==== LXDE ====
 
# Prepend an <source lang=console inline>@</source> to the <source lang=console inline>setxkbmap</source> command from above:<br><source lang=console>
@setxkbmap -layout us,apl -variant ,dyalog -option grp:switch
</source>
# Add it as a line in your user's LXDE <source lang=console inline>autostart</source> file, located at:<br><source lang=console>
~/.config/lxsession/LXDE/autostart
</source>
 
For Lubuntu versions up to and including 18.04 (before the LXQt split), the location of <source lang=console inline>autostart</source> is <source lang=console inline>~/.config/lxsession/Lubuntu/autostart</source>.
 
==== LXQt ====
 
===== GUI =====
 
# From your LXQt panel, navigate to ''Preferences'' → ''LXQt Settings'' → ''Session Settings''; alternatively, enter <source lang=console inline>lxqt-config-session</source> in your terminal emulator. You will be greeted with the following window:<br>[[File:Lxqt-session-settings.png|frameless|LXQt Autostart menu of Session Settings window]]
# Select the <source lang=console inline>LXQt Autostart</source> dropdown (it will be highlighted as shown above) and click the <kbd>Add</kbd> button to display the following pop-up window:<br>[[File:Lxqt-add-autostart.png|frameless|LXQt add a new autostart menu item]]
# Provide a name, enter your <code>setxkbmap</code> command, and click <kbd>OK</kbd> when finished.
 
===== Terminal =====
 
The above GUI approach merely creates a <source lang=console inline>.desktop</source> file in the user's <source lang=console inline>~/.config/autostart</source>. Create your own file in the <source lang=console inline>autostart</source> directory whose contents are as follows, to replicate the functionality achieved through the GUI:
 
<source lang=ini>
[Desktop Entry]
Exec=setxkbmap -layout us,apl -variant ,dyalog -option grp:switch
Name=apl-keyboard
OnlyShowIn=LXQt;
Type=Application
Version=1.0
</source>
 
==== MATE ====
 
===== GUI =====
 
# Open your MATE menu (in the top-left corner of a default environment) and select ''Control Center'' at the bottom of the window:<br>[[File:Mate-kbb-setup-1.png|frameless|Launch the Control Center from the MATE menu]]
# Scroll down through the main window, and under the ''Personal'' category, select ''Startup Applications'':<br>[[File:Mate-kbb-setup-2.png|frameless|Scroll down to the Startup Applications option]]
# Click the <kbd>Add</kbd> button on the right-hand side:<br>[[File:Mate-kbb-setup-3.png|frameless|Click <kbd>Add</kbd> to add a new startup command]]
# Provide a name, enter your <code>setxkbmap</code> command, and click <kbd>Add</kbd> when finished:<br>[[File:Mate-kbb-setup-4.png|frameless|Enter the setxkbmap command you wish to use]]
 
===== Terminal =====
 
Navigate to <code>~/.config/autostart</code> and create a <code>.desktop</code> with any name that will help you remember its function.
 
Add the following to the contents of your file, customizing to suit your needs:
 
<source lang=ini>
[Desktop Entry]
Type=Application
Exec=setxkbmap -layout us,apl -variant ,dyalog -option grp:switch
Hidden=false
X-MATE-Autostart-enabled=true
Name[en_US]=apl-keyboard
Name=apl-keyboard
Comment[en_US]=
Comment=
X-MATE-Autostart-Delay=0
</source>
 
==== Xfce ====
