ayatana-indicator-keyboard: init at 24.7.0-unstable-2024-11-09

[OPNA2608]

Description of changes

WIP

Greeter:

• Indicator not synced to actual keymap used by Lomiri (presumably, indicator only shows a generic keyboard icon)
• Has all the keymaps configured via services.xserver.xkb.layout, because it parses /etc/X11/xorg.conf.d/00-keyboard.conf
• Attempts to shell out to setxkbmap -layout ... -variant ... to set keymap on switch, not sure if that works for Wayland?

Session:

• Indicator not synced to actual keymap used by Lomiri (stuck at English, even if keybind to change Lomiri keymap is pressed)
• Only has English, presumably because it checks the GSetting org.gnome.desktop.input-sources for the keymaps that are in use
• Haven't tried to add a different keymap via settings app, Lomiri is painful to navigate in our VM setup

This might need some stronger patching to be useful.
