You have to create a file .desktop to enable quick start (windows key) for ubuntu.
Two options:
extract and copy intelliJ to /opt/idea-IU/.
Create an <application>.desktop file in /usr/share/applications/.
[Desktop Entry] Name=IntelliJ IDEA Version=16.1 Exec=/opt/idea-IU/bin/idea.sh Icon=/opt/idea-IU/bin/idea.png Terminal=false StartupNotify=true Type=Application Categories=Development;IDE;
sudo chmod 644 /usr/share/applications/intellij.desktop
sudo chown root:root /usr/share/applications/intellij.desktop
create a .desktop file in ~/.local/share/applications
