Current status

  • Targeted release: Fedora 23
  • Last updated: 2015-06-12
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Plasma 5 (KDE) no longer support GtkStatusIcon and IBus provides the different icons between Plasma and other desktops. The current IBus shows a fixed IBus icon for any XKB layouts in Plasma desktop but IBus shows the XKB language prefix names on the icon in other desktops likes "EN" for "us" layout, "FR" for "fr" layout. IBus 1.6 will show the prefix names on the icon in Plasma 5 too.

The current IBus supports the compose tables of en_US, fi_FI and pt_BR and only and have the hard-coded tables in itself. IBus 1.6 will load /usr/share/X11/locale/$LOCALE/Compose with the current session locale dynamically and also load $HOME/.XCompose file for the customization.

Benefit to Fedora

  4. Enable a XKB engine

  2. Run ibus-dameon with im-chooser
  3. Enable "fi" layout engine and fi_FI compose file is loaded
  4. Customize .XCompose file
  5. Restart ibus-daemon
