Intellij launcher doesn't work on unity?

You can use "tools" > "create desktop entry", in IntelliJ itself.

1. Open a terminal, in /path/idea/bin folder
2. Start IntelliJ with ./idea.sh
3. Tools -> Generate Desktop Entry
4. Close IntelliJ
5. In the terminal, start nautilus as admin (gksudo nautilus)
6. Go to /usr/share/applications
7. Drag the new icon for IntelliJ to your launcher

event with create desktop entry there still an error, because the launcher is not reading JDK_HOME configuration.

so after creating the desktop entry , right click on the launcher and select properties then add bash -i before double quote in command input text exp :command [ bash -i " /home/me/ides/idea/bin/idea.sh" %f ]
