Keyboard locks in IntelliJ IDEA on Ubuntu 14.04

Solution 1:

There is a an open issue in jetbrains youtrack for intellij idea that recommend two solutions:

  1. Keyboard input may be unlocked by restarting IBus daemon from a console:

    ibus-daemon -rd
    
  2. IBus can be disabled for IDEA by unsetting env. variable XMODIFIERS, but ability to input national characters in IDEA will be lost:

    XMODIFIERS="" idea.sh
    

I have used the second one and fixed my problem.

Solution 2:

I was able to solve it with what I found here that is basically adding export XMODIFIERS="" on idea.sh
