installed xneur. like successfully.in the system tray does not appear. launched via search applications. highlight the words "xneur started", there was an awful sound when typing, has a brain like a woodpecker. made the icon on the toolbar. by clicking on the icon xneur nothing happens, settings are not open, and by the way when I write in the wrong layout, nothing changes. to remove horrible sound could only stop the program by using pkill xneur . appears that the program is stopped. how can I configure this program and how it should work? ps do not judge strictly, in Ubuntu newbie.
