A small minor issue in Ubuntu. is a random bug which causes the IDEs to loose cursor, therefore it seems like your IDEs is frozen but it's not you still able to perform mouse clicks and select menus but you just can't type. There's a bug open for this issue but because it's difficult to resolve because it occurs randomly. This may seem frustrating but there's a simple work around for this.

	#!/bin/bash

	clear

	echo "webstorm or rubymine keyboard input reset"
