It is not straightforward to have your favorite programs that are not installed via package manager appear on Ubuntu (14.04) launcher. Couple of ways to do that: Sometimes, when the program is up, you can just right click and say “add to launcher”. It would work for most programs. However, this will fail for editors such as PyCharm that maintain project state and the launcher added this way will point to the specific project. The right way to do is this: Create a .desktop entry For instance, for pycharm, do : $ sudo nano /usr/share/applications/pycharm.desktop [Desktop Entry] Name=PyCharm Type=Application Exec=/home/hvishwanath/Downloads/pycharm-community-4.0.5/bin/pycharm.sh Terminal=false Icon=/home/hvishwanath/Downloads/pycharm-community-4.0.5/bin/pycharm.png Comment=PyCharm community edition 4.0.5 NoDisplay=false Categories=Development;IDE Name[en]=pycharm.desktop * You can then search for the entry in main “Search” in the launcher, and simply drag and drop the pycharm.desktop entry that you would find on to the launcher. That is it.
