Sometimes when running IntelliJ it completely blocks all keyboard inputs in the program. E.g. I can click around a document with the mouse, I can even right click + paste. I cannot, however write anything through the keyboard or navigate with the arrows inside a document or between documents for that matter.
The only keyboard related actions that work seem to be system related; alt + tab, ctrl + alt + delete, caps lock etc. also when tabbing to another window the keyboard works fine, so it is not a hardware issue.
This seem to occur when a popup is active and I tab out of IntelliJ and back in, but I am not certain that this is the case.
I would like to stress that it is not merely the currently open document that I cannot modify, since I CAN insert text and remove it using mouse commands only (the file is not write protected or anything like that), it seem to be a complete block of all keyboard inputs in IntelliJ.
The only workaround I have found is to restart IntelliJ.
I am running Ubuntu 13.10. More or less all projects I work with in IntelliJ are maven projects. It happens roughly once a day when using IntelliJ as main IDE.
This seems to be an IBus issue. The bug is not localized yet but it's clear it is not in IDEA - rather in IBus or possibly in Java X events handling code.
Workarounds:
- IBus can be disabled for IDEA by unsetting env. variable XMODIFIERS. So, add the following lines to
$IDEA_HOME/bin/idea.sh at almost the end of the file:
... XMODIFIERS=idea.sh export XMODIFIERS # --------------------------------------------------------------------- # Run the IDE. # --------------------------------------------------------------------- ...
- Have been reported that run
ibus-daemon -rd is not recommended as it may cause JVM crash. However, it also seems to work.

I ran into the same issue with Ubuntu 14.04 LTS and IDEA 14+. I'm currently running IDEA 14.1.3.
The XMODIFIERS fix seemed to work for a while, but then the issue returned.
Changing Setup->Language->Keyboard input method system from iBus to none did not fix it for me.
What finally worked was switching JDKs from
java version "1.7.0_79" OpenJDK Runtime Environment (IcedTea 2.5.5) (7u79-2.5.5-0ubuntu0.14.04.2) OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
to
java version "1.7.0_75" Java(TM) SE Runtime Environment (build 1.7.0_75-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)
using
export IDEA_JDK=/home/don/apps/jdk1.7.0_75/
