NixOS: Libreoffice in distrobox does not use Adwaita dark theme

GTK_THEME=Adwaita:dark libreoffic
or set in fish config:
set -x GTK_THEME Adwaita:dark

NixOS: Firefox in distrobox does not use Adwiata theme (no hand mouse cursor)

NixOS injects its Nix store paths into XCURSOR_PATH so the host system finds cursors in /nix/store/..., and distrobox inherits that variable. Inside the Arch container those paths don't exist, so libxcursor found nothing and silently fell back to the default arrow for every cursor change.
vim .config/fish/config.fish
set -e XCURSOR_PATH
set -x XCURSOR_PATH /usr/share/icons ~/.icons


When creating launcher for firefox in xfce4, have to reset `XCURSOR_PATH`:
/run/current-system/sw/bin/distrobox-enter -n abox -- bash -c 'XCURSOR_PATH=/usr/share/icons /usr/lib/firefox/firefox %u '

terminator: change size and location

terminator --geometry=2420x650+80+800

NixOs: Can't start terminator from distrobox on nixos

TypeError: unknown signal name: changed::font-name

The error TypeError: unknown signal name: changed::font-name occurs because Terminator is trying to connect to a GSettings signal for org.gnome.desktop.interface (font settings), but the required GSettings schemas are missing or inaccessible inside the distrobox container.
distrobox-enter -n abox -- bash -c 'unset LD_LIBRARY_PATH GI_TYPELIB_PATH GIO_MODULE_DIR GSETTINGS_SCHEMA_DIR; terminator'
