How to fix: RubyMine occasionally no longer accepts keyboard input
From time to time, RubyMine suddenly did not accept any keyboard input and felt crashed, while mouse interaction was still possible. This apparently happens to all IntelliJ IDEs, especially on Ubuntu 14.04.
I've managed to fix it by having a shell script that exports
XMODIFIERS="" when launching RubyMine, like this:
#!/bin/sh XMODIFIERS= /home/arne/rubymine/bin/rubymine.sh
It has been working reliably for me ever since, at least until RubyMine 8.
An alternate solution suggested on the Jetbrains issue tracker is setting
#!/bin/sh IBUS_ENABLE_SYNC_MODE=1 /home/arne/rubymine/bin/rubymine.sh
This seems fix issues on RubyMine 8.
The benefit of an extra launcher file is that you can upgrade RubyMine and don't have to touch your launcher.
