Using multiple keyboard layouts

The official Qubes OS docs only cover how to change the layout globally - ie. both for dom0 and VMs, with a single layout.

This document depicts several ways of using multiple keyboard layouts and being able to quickly switch between them.

Recommended setup

Run setxkbmap in each VM (dom0 will be configured with only one layout, since running setxkbmap... in dom0 would probably interfere with the VMs).

For instance the following command would alternate between the US English and the Bulgarian phonetic layout when pressing both shift keys:

setxkbmap -layout "us,bg(phonetic)" -option "grp:shifts_toggle"

To automatically run the setxkbmap command when the VM starts, add a /etc/xdg/autostart/setxkbmap.desktop file in the VM's template with the following content:

[Desktop Entry]
Name=Configure multiple keyboard layouts
Exec=setxkbmap -layout "us,bg(phonetic)" -option "grp:shifts_toggle"
Terminal=false
Type=Application

If you prefer to have per-VM rather than per-template setxkbmap commands create a /rw/config/setxkbmap.desktop with the same content as above and add the following line to /rw/config/rc.local:

cp /rw/config/setxkbmap.desktop /etc/xdg/autostart

Note: the reason we can't put the setxkbmap command in the rc.local script is because the X server isn't running when rc.local is executed.

Alternatively, you could add the setxkbmap command to your profile's .bashrc file if you use terminals to start applications.

Alternative setups

  • Configuring a keyboard shortcut in dom0 that would issue qvm-run vname 'setxkbmap...' to the VM whose window is under the mouse pointer (using xprop -id $(xdotool getactivewindow) ). This is a bit convoluted and qvm-run is sometimes slow when the system is under heavy I/O usage, so the layout switch doesn't happen immediately which is annoying.
  • Change the layout in dom0 with setxkbmap .... This isn't optimal because:
    • there's no way to know which layout is used when typing the screensaver's password
    • sometimes the keyboard layout would not be propagated to one of the VMs, requiring a reboot of the VM.
  • Once Qubes OS gains support for keyboard layout propagation from dom0 to VMs (see this official issue) one could use the desktop environment's keyboard layout switcher (eg. Xfce Keyboard Layout switcher). It is not clear however if this solution won't exhibit the issues as above when running setxkbmap ... in dom0.
  • Change the layout in dom0 with localectl: it's a no-go as it requires a reboot
