If you’re using intellij under Ubuntu you probably noticed the keyboard stops working sometimes just in the IDE.
This is very anoying and there is an open issue: https://youtrack.jetbrains.com/issue/IDEA-78860
If you want to enable again the keyboard execute this command on any terminal:
ibus-daemon -rd
This seems to work in versions 14.04 and 14.10.

I’ve had this issue several times, your solution works on Ubuntu 20.04, thanks a lot.
