How to use XCompose on Wayland?

I'm using a popular ~/.XCompose file. For that to work on X11 one had to set environment variables like:


But with Gnome-On-Wayland session this doesn't seem to do anything, perhaps because xim is X11 specific. Alternatively I could probably try IBus, but its Compose table never produces anything defined in the ~/.XCompose, i.e. greek letters, math symbols, nothing. It probably just ignores the file.

I am not sure whether ibus simulates xkb settings, or using the libxkbcommon, but setxkbmap is the way to go.

  1. Remove the *_IM_MODULE and XMODIFIERS variables. It should probably work upon setting to ibus, but I tested with them cleared off.
  2. Make sure if ibus is running (in Fedora it should by default, it's just in case you disabled it previously).
  3. Execute setxkbmap with -option to choose compose key. E.g. to use the right logo key: setxkbmap -option compose:rwin. Here's a full command I execute:

    setxkbmap -layout us,ru -option grp:rctrl_rshift_toggle,grp_led:scroll,lv3:ralt_switch,compose:rwin

    You'd probably want to set a command to be executed for every start up.

Works for both Wayland and X11.
