I’ve enabled IBus support for rapidly changing the input method. Neither the keyboard shortcut nor the menu selection actually alters the input method. The visual indicator changes but the keyboard doesn’t change.
The only way to change it is to use the Keyboard settings in the Control Panel. In Language Support I’ve enabled IBus as the keyboard input method system - but there is no difference.
It would be great if you’d in short mentioned what was the problem, like, if it wasn’t some global variable set, or something. It would be interesting for peoples, who came here on occasion, like me, and possibly even helpful.
