Just on a wild guess, I launched "Add to Panel" and added the "Indicator Applet" — and a US flag (corresponding to my currently active keyboard layout) showed up in the panel along the top of the screen.
Although (re-)adding the indicator applet seems to have fixed the problem, there is still the question of why the indicator applet became broken in the first place. -- New Lucid keyboard layout indicator does not indicate current layout https://bugs.launchpad.net/bugs/531173 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
