Keyboard layout indicator sometimes disappears Ubuntu 18.04.1 after some update [duplicate]
Solution 1:
It is not linked with Extension. I have same problem and no extensions installed at all.
Also when indicator disappear, clicking "Show Keyboard Layout" is not working at all
Switching with keyboard or mouse will fix problem.
Problem is there only on restore after sleep, never after fresh boot. Also happen after locking/coming from lock screen.
