Obtain the best look ever for Intellj on Linux

(1) install freetype
$ sudo apt-get install libfreetype6

(2) install infinality patch (https://launchpad.net/~no1wantdthisname/+archive/ppa)
$ sudo add-apt-repository ppa:no1wantdthisname/ppa
$ sudo apt-get update
$ sudo apt-get install fontconfig-infinality

I had to do the following afterwards:
$ sudo rm /etc/fonts/conf.avail/52-infinality.conf
$ sudo ln -s /etc/fonts/infinality/infinality.conf /etc/fonts/conf.avail/52-infinality.conf

To use Windows 7 like font rendering do the following:
$ sudo /etc/fonts/infinality/infctl.sh setstyle osx
Set USE_STYLE to "osx" in /etc/profile.d/infinality-settings.sh

(3) install font fixed OpenJDK (https://launchpad.net/~no1wantdthisname/+archive/openjdk-fontfix)
$ sudo add-apt-repository ppa:no1wantdthisname/openjdk-fontfix
$ sudo apt-get update
$ sudo apt-get install openjdk-7-jdk

To use this JDK only for IntelliJ, prepend this line to bin/idea.sh:
IDEA_JDK="/usr/lib/jvm/java-1.7.0-openjdk-amd64"

(4) JVM options
Add the following options to the .vmoptions file of IntelliJ
-Dawt.useSystemAAFontSettings=lcd
-Dswing.aatext=true

(5)
Perform a reboot

(6)
See the result with default Darcula theme in attachment.

Hope this helps someone!
