fix(niri): Super+Space switches keyboard layout (us/ar)#13
Merged
Conversation
Niri grabs key events for its own binds before xkbcommon's group-toggle action fires, so the xkb `grp:ctrl_space_toggle` option — which does switch layouts under X11/LeftWM — was a no-op in Niri. Super+Space did nothing. Add Niri's native `switch-layout "next"` action on Mod+Space (= Super+Space) and document the X11-vs-Niri difference at the xkb block. The X11 paths (home.keyboard, services.xserver.xkb) keep grp:ctrl_space_toggle untouched. Verified with `niri validate` (config is valid). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Problem
In Niri, Super+Space did not change the writing language. The Niri config relied solely on the xkb option
grp:ctrl_space_toggle, but:grp:*_toggleoptions are a no-op under Niri (they do work under X11/LeftWM).Fix
Mod+Space { switch-layout "next"; }(Mod = Super) with a hotkey-overlay title.home.keyboard,services.xserver.xkb) keepgrp:ctrl_space_toggle— it genuinely works under LeftWM.Verification
nix evalof the toplevel drvPath — passes.niri validateon the renderedconfig.kdl— config is valid.🤖 Generated with Claude Code
